Abstract
Persistent Müllerian duct syndrome (PMDS) is a rare sexual development disorder. It is even more rarely associated with transverse testicular ectopia (TTE), a rare form of testicular ectopia, in which both testes descend through a single inguinal canal and are present in the same hemiscrotum. PMDS with TTE is associated with 18%-33% malignant transformation. Here we report the case of a 48-year-old man who presented with a large right inguinoscrotal swelling and on evaluation was found to have a large right testicular mass with complete right inguinal hernia, undescended left testis and a central abdominal mass. On evaluation with contrast-enhanced computed tomography abdomen and pelvis and image-guided biopsy he was diagnosed with mixed germ cell tumour of the right testis (predominantly a seminoma) with a retroperitoneal nodal mass and absent left testis, for which he received chemotherapy. Post-chemotherapy he underwent surgery and was diagnosed intraoperatively with PMDS along with TTE and testicular malignancy arising from the ectopic left testis. Postoperative recovery and follow-up were uneventful. Most cases of PMDS are diagnosed early in life. They present clinically with unilateral or bilateral undescended testis with inguinal hernia. In adults, PMDS is usually associated with male infertility. However, TTE is associated with an increased risk of testicular tumours if undiagnosed until adulthood. In adults PMDS with TTE is usually an intraoperative finding and is commonly associated with malignancy in the ectopic/undescended testis.

Comparison of scrotal and inguinal orchiopexy for palpable undescended testis: a meta-analysis of randomized controlled trials. Pediatr Surg Int 2024; 40:74. [PMID: 38451346 DOI: 10.1007/s00383-024-05655-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 02/11/2024] [Indexed: 03/08/2024]
Abstract
INTRODUCTION Scrotal and inguinal orchiopexy are two commonly used surgical approaches for palpable undescended testis (UDT), each with distinct advantages. However, the optimal approach remains a matter of debate, warranting a comprehensive meta-analysis of randomized controlled trials (RCTs) to guide clinical decision-making. MATERIALS AND METHODS A comprehensive literature search was conducted, adhering to PRISMA guidelines, to select RCTs comparing scrotal and inguinal orchiopexy for palpable UDT. Eight RCTs were selected for meta-analysis. Outcome measures included operative time, hospitalization duration, total complications, wound infection or dehiscence, testicular atrophy or hypotrophy, and testicular re-ascent rate. The evaluation of the study's quality was conducted by utilizing the revised Cochrane risk-of-bias tool. RESULTS Scrotal orchiopexy showed significantly shorter operative time compared to the inguinal approach (WMD: - 15.06 min; 95% CI: - 21.04 to - 9.08). However, there was no significant difference in hospitalization duration (WMD: - 0.72 days; 95% CI: - 1.89-0.45), total complications (OR: 1.08; 95% CI: 0.70-1.66), wound infection or dehiscence (OR: 0.73; 95% CI: 0.27-1.99), testicular atrophy or hypotrophy (OR: 1.03; 95% CI: 0.38-2.78), and testicular re-ascent (OR: 1.43; 95% CI: 0.67-3.06) between the two approaches. A small proportion of cases (7.3%) required conversion from scrotal to inguinal orchiopexy due to specific anatomical challenges. CONCLUSION Both scrotal and inguinal orchiopexy are safe and effective for palpable UDT, with comparable outcomes in terms of hospitalization and complications. Scrotal orchiopexy offers the advantage of shorter operative time. Clinicians can use this evidence to make informed decisions on the surgical approach for palpable UDT.

A closer look to the timing of orchidopexy in undescended testes and adherence to the AWMF-guideline. Pediatr Surg Int 2024; 40:60. [PMID: 38421443 PMCID: PMC10904547 DOI: 10.1007/s00383-024-05659-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 02/15/2024] [Indexed: 03/02/2024]
Abstract
BACKGROUND To lower the risk of testicular malignancies and subfertility, international guidelines recommend orchidopexy for undescended testis (UDT) before the age of 12-18 months. Previous studies reported low rates of 5-15% of timely surgery. Most of these studies are based on DRG and OPS code-based data from healthcare system institutions that do not distinguish between congenital and acquired UDT. METHODS In a retrospective study data of all boys who underwent orchidopexy in a university hospital and two outpatient surgical departments from 2009 to 2022 were analyzed. The data differentiates congenital from acquired UDT. RESULTS Out of 2694 patients, 1843 (68.4%) had congenital and 851 (31.6%) had acquired UDT. In 24.9% of congenital cases surgery was performed before the age of 12 months. The median age at surgery for congenital UDT was 16 months (range 7-202). Over the years there was an increased rate of boys operated on before the age of 2 (40% in 2009, 60% in 2022). The median age fluctuated over the years between 21 and 11 months without a trend to younger ages.. The covid pandemic did not lead to an increase of the median age at surgery. The median time between referral and surgery was 46 days (range 1-1836). Reasons for surgery after 12 months of age were a delayed referral to pediatric surgeries (51.2%), followed by relevant comorbidities (28.2%). CONCLUSION Compared to recent literature, out data show that a closer look at details enables a more realistic approach. Still, there is no trend towards the recommended age for surgical treatment observable, but the rate of timely operated boys with congenital UDT is significantly higher than stated in literature.

Abstract
Undescended testis (UDT, cryptorchidism) is the most common congenital anomaly of the genital tract. Despite its high incidence, the management of UDT varies between specialties (urology, pediatric surgery, pediatric urology, pediatric endocrinology). Therefore, as the European Association of Urology - Young Academic Urologists Pediatric Urology Working Group, we requested experts around the world to express their own personal approaches against various case scenarios of UDT in order to explore their individual reasoning. We intended to broaden the perspectives of our colleagues who deal with the treatment of this frequent genital malformation.

Abstract
PURPOSE To evaluate the feasibility of single-site laparoscopic orchiopexy for palpable undescended testes in children. METHODS We prospectively studied patients with undescended testes between July 2021 and June 2022. In total, 223 patients were included in our study: 105 underwent single-site laparoscopic orchiopexy and 118 underwent conventional laparoscopic orchiopexy. During single-site laparoscopic orchiopexy, 3 ports were inserted within the umbilicus. RESULTS No differences were observed between the groups in terms of age and laterality. For unilateral undescended testes, the operating time was longer in the single site group than in the conventional group at the early stages (55.31 ± 12.04 min vs. 48.14 ± 14.39 min, P = 0.007), but it was similar to the conventional group at the later stages (48.82 ± 13.49 min vs. 48.14 ± 14.39 min, P = 0.78). Testicular ascent occurred in one patient from each group. There was no significant difference in the success rate between the single-site group and the conventional group (99.0% vs. 99.2%, P = 0.93). In the single-site group, no visible abdominal scarring was observed, while in the conventional group, there were two noticeable scars on the abdomen. CONCLUSION Single-site laparoscopic orchiopexy offers superior cosmetic results and comparable success rates compared to conventional laparoscopic orchiopexy for palpable undescended testes.

Immediate Versus Delayed Surgical Management of Infant Cryptorchidism With Inguinal Hernia. J Pediatr Surg 2024; 59:134-137. [PMID: 37858390 DOI: 10.1016/j.jpedsurg.2023.09.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Accepted: 09/07/2023] [Indexed: 10/21/2023]
Abstract
INTRODUCTION Cryptorchidism is commonly treated with orchiopexy at 6-12 months of age, often allowing time for undescended testicle(s) (UT) to descend spontaneously. However, when an inguinal hernia (IH) is also present, some surgeons perform orchiopexy and inguinal hernia repair (IHR) immediately rather than delaying surgery. We hypothesize that early surgical intervention provides no benefit for newborns with both IH and UT. METHODS The Nationwide Readmissions Database was used to identify newborns with diagnoses of both IH and UT from 2010 to 2014. Patients were stratified by management: IHR performed on initial admission (Repair) or not (Deferral). Demographics, outcomes, and complications were compared. Results were weighted for national estimates. RESULTS We analyzed 1306 newborns (64% premature) diagnosed with both IH and UT. IHR was performed at index admission in 30%. Repair was more common in premature babies (43% vs. 8% full-term, p < 0.001) and patients with congenital anomalies (33% vs. 27% without congenital anomaly, p = 0.012). There was no difference in readmission rates. Repair patients had higher rates of orchiectomy than did Deferral. No Deferral patients were readmitted for bowel resection, and <1% were readmitted for orchiectomy or hernia incarceration. CONCLUSION In newborns with UT and IH, immediate repair is not associated with improved outcomes. Even with incarceration on initial presentation, rates of readmission with incarceration or bowel compromise for patients who undergo Deferral of surgery are minimal. Moreover, Repair newborns have higher rates of orchiectomy. We found no benefit to early operative intervention; thus, we recommend waiting until 6-12 months of age to reassess for surgery.

Abstract
PURPOSE Children with undescended testes (UDTs) undergoing orchiopexy at a later age reportedly experience more negative effects on post-orchiopexy testicular volume (TV). This study aimed to investigate the effect of orchiopexy according to the age at operation. METHODS We included 93 patients (127 testes) who underwent orchiopexy between 2008 and 2020. According to their age at orchiopexy, they were divided into Group 1 (< 24 months; n = 36, median follow-up: 17 [14-39] months) and Group 2 (≥ 24 months; n = 57, median follow-up: 16 [13-34] months). TV was measured with ultrasonography preoperatively and postoperatively. In unilateral UDTs, the testicular volume rates (TVR) were calculated as diseased-side TV/intact-side TV × 100%. A TVR < 50% indicated preoperative testicular atrophy (pre-op TA), whereas volume loss ≥ 50% from baseline indicated postoperative testicular atrophy (post-op TA). RESULTS Only seven patients experienced pre-op TA. The TV of these 14 atrophic testes improved after orchiopexy (TVR: 100% (7/7) in Group 1 and 85% (6/7) in Group 2). Furthermore, the median TVR significantly improved after orchiectomy, from 27 to 58% (p < 0.01) and from 32 to 61% in Groups 1 and 2 (p < 0.05), respectively. Post-op TA was found in four testes (8%) in Group 1 and three testes (4%) in Group 2. Multivariate analysis showed that only preoperative testicular location predicted post-op TA. CONCLUSION Post-orchiopexy TA may occur regardless of the patient's age at orchiopexy, and orchiopexy is recommended irrespective of age at diagnosis.

Abstract
PURPOSE This study aimed to investigate the incidence and clinical factors associated with undescended testes (UDT) in patients with congenital diaphragmatic hernia (CDH). METHODS We retrospectively reviewed the incidence of UDT in male neonates admitted to our institution and underwent surgery for CDH between January 2006 and December 2022. Patients were divided into two groups based on the presence or absence of UDT, and risk factors for UDT were compared between the two groups. RESULTS Among the 66 male neonates with CDH, 16 (24.2%) developed UDT. Patients with UDT had a significantly smaller gestational age (p = 0.026), lower birth weight (p = 0.042), and lower Apgar score at 1 min (p = 0.016) than those without UDT. They had a significantly higher incidence of large diaphragmatic defects (p = 0.005), received more patch closures (p = 0.020), had a longer mechanical ventilation period (p = 0.034), and longer hospital stay (p = 0.028). Multiple logistic regression analysis revealed that large diaphragmatic defect was an independent risk factor for UDT (adjusted odds ratio of 3.87). CONCLUSION CDH and UDT are strongly correlated. In patients with CDH, the incidence of UDT was related not only to patients' prematurity but also to the large diaphragmatic defect. Large diaphragmatic defect is an independent risk factor for UDT in patients with CDH.

Abstract
Testicular torsion in undescended testicles (UDTs) is a rare clinical combination. Symptoms can be ambiguous and misinterpreted as indications of other common conditions. Moreover, late identification of a UDT may significantly delay the diagnosis and lead to adverse outcomes. Here, we report a case of a 16-year-old boy with progressive pain in the right inguinal region and a history of right UDT. Intraoperatively, he was diagnosed with testicular torsion, and an orchiectomy was performed. This report also underscores the importance of an early UDT torsion diagnosis.

Bibliometric analysis of scientific publications on cryptorchidism: Research hotspots and trends between 2000 and 2022. Heliyon 2023; 9:e19722. [PMID: 37809395 PMCID: PMC10559000 DOI: 10.1016/j.heliyon.2023.e19722] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2022] [Revised: 08/28/2023] [Accepted: 08/31/2023] [Indexed: 10/10/2023] Open
Abstract
Background Cryptorchidism is defined as failure of unilateral or bilateral testicular descent, which increases the risk of infertility and testicular carcinoma. Although there is much research on cryptorchidism, few studies have used the bibliometric analysis method. The purpose of this study was to conduct a comprehensive analysis of cryptorchidism from muti-dimensional perspectives to summarize the research hotspots and trends in cryptorchidism research. Methods Relevant studies on cryptorchidism were retrieved from the Web of Science Core Collection (WoSCC) database from 2000 to 2022. A comprehensive bibliometric analysis of cryptorchidism was performed by using the CiteSpace, Tableau Public, and VOSviewer software, including the annual distributions of publications, countries, authors, institutions, journals, references, and keywords. Results From January 1st, 2000 to May 17th, 2022, a total of 5023 papers concerning cryptorchidism were identified for analysis. The USA contributed the most publications (n = 1193) in this field, and the annual number of publications rose rapidly in China. The University of Melbourne published the largest number of papers (n = 131). "Hutson, John M." was the most core author ranked by publications (n = 51), and "Skakkebaek, Niels E." enjoyed the largest number of citations (4441). The JOURNAL OF UROLOGY published the largest number of papers (n = 225), while the average citations per publication of the 75 papers in HUMAN REPRODUCTION reached 62.38. Additionally, burstness analysis of references and keywords showed that cryptorchidism research was mainly focused on the exploration of the optimal mode of treatment for cryptorchidism, including hypogonadism such as Kallmann syndrome and Klinefelter syndrome. Conclusion Cryptorchidism has attracted continuous attention from the scientific community concerned. International collaboration in the field has witnessed significant growth in recent years and remains essential to further enhance collaborative efforts between scholars from different countries. In addition, the exploration of the optimal treatment modality for cryptorchidism, especially in the prevention of adult infertility, remains a major focus of future research. High-quality follow-up studies are also needed in the future. The pathogenesis (especially at the genetic level) and treatment of hypogonadism such as Kallmann syndrome and Klinefelter syndrome have attracted increasing attention recently, which may usher in some breakthroughs in coming years.

Abstract
BACKGROUND Accurate referral of boys with suspected undescended testes (UDT) is of importance to preserve fertility and reduce risk of future testicular cancer. While late referral is well studied, there is less knowledge about incorrect referrals, hence, referral of boys with normal testes. OBJECTIVE To evaluate the proportion of UDT referrals that did not lead to surgery or follow-up, and to assess risk factors for referral of boys with normal testes. STUDY DESIGN All UDT referrals to a tertiary center of pediatric surgery during 2019-2020 were retrospectively assessed. Only children with suspected UDT in the referral (not suspected retractile testicles) were included. Primary outcome was normal testes at examination by a pediatric urologist. Independent variables were age, season, region of residence, referring care unit, referrer's educational level, referrer's findings, and ultrasound result. Risk factors for not needing surgery/follow-up were assessed with logistic regression and presented as adjusted odds ratios with a 95% confidence interval (aOR, [95% CI]). RESULTS A total of 378 out of 740 included boys (51.1%) had normal testes. Patients >4 years (aOR 0,53, 95% CI [0,30-0,94]), referrals from pediatric clinics (aOR 0.27, 95% CI [0.14-0.51]) or surgery clinics (aOR 0.06, 95% CI [0.01-0.38]) had lower risk of normal testes. Boys referred during spring (aOR 1.80, 95% CI [1.06-3.05]), by a non-specialist physician (aOR 1.58, 95% CI [1.01-2.48]) or referrer's description of bilateral UDT (aOR 2.34, 95% CI [1.58-3.45]), or retractile testes (aOR 6.99, 95% CI [3.61-13.55]) had higher risk of not needing surgery/follow-up. None of the referred boys that had normal testes had been re-admitted at the end of this study (October 2022). DISCUSSION Over 50% of boys referred for UDT had normal testes. This is higher or equal to previous reports. Efforts to reduce this rate should in our setting probably be directed towards well-child centers and training in examination of testicles. The main limitation of this study is the retrospective design and the rather short follow-up time, which however should have very modest effect on the main findings. CONCLUSION Over 50% of boys referred for UDT have normal testes. A national survey regarding the management and examination of boys testicles has been launched and directed at well-child centers to further evaluate the findings of the current study.

Abstract
The descent of the testis and the development of an inguinal hernia were the earliest published scientific work by John Hunter, the Scottish surgeon and anatomist who is acknowledged as the father of scientific surgery. Hunter's anatomic descriptions are the ones we use today to describe the prenatal descent of the testis and to explain the pathogenesis of an undescended testis and inguinal hernia in infancy. His work appeared in print in 1762, not as a formal publication but as an addendum to a screed written by his older brother William publicly accusing Percival Pott of pirating John's observations on the pathogenesis of an inguinal hernia and publishing them as his own, an early example of scientific rivalry.

The optimum cut-off value of contralateral testis size in the prediction of monorchidism in children with nonpalpable testis: A systematic review. J Pediatr Urol 2023:S1477-5131(23)00092-X. [PMID: 36964019 DOI: 10.1016/j.jpurol.2023.03.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/28/2022] [Revised: 11/21/2022] [Accepted: 03/08/2023] [Indexed: 03/26/2023]
Abstract
BACKGROUND Contralateral Testis Hypertrophy (CTH) is a clinical marker that could be used to guide the choice of the main surgical strategy. In patients with a Non-palpable Testis (NPT), the degree of CTH as measured by testicular length or volume has been shown to be able to predict whether the undescended testis will survive. OBJECTIVE The purpose of this study was to establish the proper cut-off for identifying non-viable testes based on the current literature. DESIGN We systematically searched several medical databases as well as Google Scholar search engines for references and citations. All the studies that reported CTH as a result of NPT in prepubertal boys were included. Data from the included articles was gathered by two independent reviewers. The checklist developed by the Joanna Briggs Institute (JBI) was used to evaluate the methodological quality of the studies that were included. Due to the incredibly high degree of heterogeneity among the studies, no meta-analysis was done. RESULTS The current systematic review included 17 studies that assessed the cut-off point to detect non-viable testis. The size and length of the testes were taken into consideration based on our findings. We found that different studies reported various ideal cut-off values for predicting non-viable testes, which can be brought on by various measuring techniques, evaluation ages, and patient groupings. The difference in testis volume was greater than the difference in its length, which can be attributable to the fact that some studies used an orchidometer to measure the testis's length directly or indirectly. CONCLUSION According to the results of our study, it seems that defining a cut point for diagnosis of CTH based on the size of the testis, cannot demonstrate the absence of a non-palpable testis.

Are we still too late? Timing of orchidopexy. Eur J Pediatr 2023; 182:1221-1227.

Abstract
An undescended testis is the most common genitourinary disease in boys. The German guidelines, first published in 2009, proposed the timing of orchidopexy to be before 12 months of age. The aim of the study was to analyze the implementation of these guidelines 10 years after publication. The national cumulative statistics of hospital admissions, provided by the Institute for the Remuneration System in Hospitals (InEK), and the statistics concerning procedures performed in private pediatric surgical practices of the professional association of pediatric surgeons (BNKD) regarding the time of surgeries for the year 2019 were analyzed. Data from InEK included all German hospital admissions. Data from BNKD included data from 48 private pediatric surgical practices. The hospitals treated 6476 inpatients with undescended testis, and 3255 patients were operated in private practices. Regarding the age at treatment, 15% of the hospital patients and 5% of the private practice patients were younger than 1 year and fulfilled the guideline recommendations. Forty percent of the hospital patients and 29% of the private practice patients were 1 or 2 years of age. All other patients were 3 years of age or older at the time of orchidopexy. Conclusions: The rate of orchidopexy within the first 12 months of life is remarkably low even 10 years after the publication of the guidelines. Awareness of the existing guideline must be increased for both referring pediatric and general practitioners. What is Known: • In Germany, orchidopexy is performed by pediatric surgeons and urologists either in hospital settings or in private practices. • Most international guidelines set the age for surgical treatment of undescended testis between 12 and 18 months of age. The German guidelines, published in 2009, sets the time-limit at one year of age. Until five years after publication of the German guidelines, the number of patients treated before the first year of life was low; studies show an orchidopexy ratebetween 8% and 19% during this time. What is New: • This study the first to cover all administered hospital patients in Germany and a large group of patients treated in private practices. It contains the largest group of German patients with undescended testis. • Although almost all children participate in the routine check-up at the age of seven months, which includes investigation for undescended testis, adherence to the orchidopexy guidelines is still low. Only 15% of the hospital patients and 5% of the patients in private practice were treated before their first birthdays.

Unilateral transverse testicular ectopia with recurrence of inguinal hernia: a case report. J Med Case Rep 2023; 17:69. [PMID: 36843109 PMCID: PMC9969688 DOI: 10.1186/s13256-023-03782-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Accepted: 01/18/2023] [Indexed: 02/28/2023] Open
Abstract
BACKGROUND Crossed testicular ectopia or transverse testicular ectopia is an extremely rare urogenital anomaly. In this condition, on average at 4 years of age the testes migrate through the inguinal canal and one or both testes may turn up in the abdomen, inguinal region, or in the hemiscrotum, with an empty contralateral hemiscrotum. Our case report documents transverse testicular ectopia in a 5-year-old boy who presented with right inguinal hernia and nonpalpable left testis. He underwent previous right herniorrhaphy at the age of 1 year. CASE PRESENTATION A 5-year-old Iranian boy was diagnosed with a right inguinal hernia. He underwent right inguinal herniorrhaphy at the age of 1 year. For this case report, the hernia symptoms had returned. Both testicles were palpated in the right scrotum, an ultrasound examination also revealed both testicles to be present in the right scrotum, and a hernia sac located in the right inguinal region with an internal ring. The patient was recommended to undergo a surgical reconstruction. Surgical reconstruction was performed by crossing the left testis in the transseptal orchiopexy technique. CONCLUSION In patients with cryptorchidism on one side and an inguinal hernia on the other side, the surgeon must consider a rare condition known as transverse testicular ectopia. Sonography can be helpful for diagnosing cases where transverse testicular ectopia is suspected, evaluating other anomalies, and selecting the most appropriate treatment.

Low-dose every-second-day LHRH treatment following bilateral orchidopexy in children with bilateral cryptorchidism may improve their fertility outcome. J Pediatr Urol 2023; 19:128.e1-128.e7. [PMID: 36336621 DOI: 10.1016/j.jpurol.2022.10.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/11/2022] [Revised: 09/14/2022] [Accepted: 10/11/2022] [Indexed: 11/05/2022]
Abstract
INTRODUCTION/BACKGROUND Currently the standard treatment for bilateral cryptorchidism is bilateral surgical orchidopexy. Whether a hormonal treatment should be routinely administered postoperatively to increase fertility is debatable. Low-dose postoperative luteinizing hormone releasing hormone (LHRH) can increase spermatogonial numbers, but the effect of native LHRH (Kryptocur®) on adult fertility is unclear. OBJECTIVE To determine if low-dose every-second-day postoperative LHRH administration in children with bilateral cryptorchidism improves fertility in adulthood and if Nistal testicular histological grading could guide the decision to administer LHRH. STUDY DESIGN METHODS All patients, actually at least 16yr of age, that underwent a bilateral orchidolysis and orchidopexy for bilateral cryptorchidism (surgery between 1997 and 2018) were contacted and offered a clinical exam, hormone levels, sperm analysis, and a scrotal ultrasound. At the original surgery, testicular biopsy was performed (if 60% of the tubuli contain >1 spermatogonia, this is normal = Nistal-1, if 30-60% filled = Nistal-2, if <30% = Nistal-3 and if Sertoli only = Nistal-4) and if in at least one testis impaired. A low dose native LHRH treatment was offered to the patients, as this treatment is known to increase the number of spermatogonia in a short term. Kryptocur® (LHRH, Gonadorelin, Hoechst®) was prescribed and dosed at 200 μg (one spray in one nostril) every other day for 6-8 months. RESULTS AND LIMITATIONS Forty-two men were eligible for this study. 20/42 accepted the invitation for a clinical and hormonal evaluation. 16/20 men accepted the invitation for an additional sperm analysis. Fourteen of 20 men received low-dose LHRH postoperatively in a nonrandomized manner. Three men had Nistal grade 1, eight grade 2, seven grade 3, and two had grade 4. Inhibin B levels were higher in men with Nistal 1 and 2 compared with Nistal 3 and 4 P ≤ 0.037). Severe oligospermia/azoospermia (<1 × 106/ejaculate) was observed in 33% of the treated group vs 67% of the untreated group (P ≤ 0.036.) DISCUSSION AND CONCLUSIONS: Low-dose every-second-day postoperative LHRH treatment improves fertility outcome in bilateral cryptorchidism. Histological analysis of prepubertal testes according to Nistal grading cannot be used as a predictive diagnostic test for LHRH treatment.

The role of the resistive index in predicting testicular atrophy after orchiopexy in unilateral undescended testis. Pediatr Surg Int 2022; 39:38. [PMID: 36480074 DOI: 10.1007/s00383-022-05336-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 12/02/2022] [Indexed: 12/13/2022]
Abstract
PURPOSE One of the most important complications of undescended testis (UDT) surgery is testicular atrophy (TA). We aimed to investigate the factors associated with TA in children who underwent orchiopexy for unilateral UDT. METHODS The data of 215 patients aged < 15 years who underwent orchiopexy for unilateral UDT between November 2019 and September 2022 were analyzed retrospectively. Clinical, radiological, surgical, and follow-up findings were recorded. RESULTS TA was observed in 29 (13.5%) patients. Mean resistive index (RI) values were 0.44 ± 0.06, 0.54 ± 0.09 and 0.69 ± 0.1 in low, middle and high testicular locations, respectively, and intratesticular RI increased significantly as the testis location raised (p < 0.001). After orchiopexy, the mean testis volume ratio (TVR) increased significantly (0.63 ± 0.13 vs. 0.77 ± 0.15, p < 0.001). Besides, the mean RI values decreased significantly in the postoperative follow-up (0.53 ± 0.12 vs. 0.47 ± 0.13, p < 0.001). In multivariate regression analysis, testicular high location (OR 4.332, 95% CI 2.244-6.578, p = 0.002), deferens-epididymal anomaly (OR 3.134, 95% CI 1.345-7.146, p = 0.021), TVR ≤ 0.5 (OR 5.679, 95% CI 2.953-12.892, p < 0.001) and RI ≥ 0.6 (OR 7.158, 95% CI 3.936-14.569, p < 0.001) were independent predictive factors for TA after orchiopexy. CONCLUSION Higher testis location, deferens-epididymis anomaly, preoperative TVR and RI were independent predictive factors for TA after orchiopexy in unilateral UDT. The results of the study will help surgeons to predict TA before orchiopexy.

Japan's comprehensive undescended testis screening program: incidence of ascending testis after screening. Pediatr Surg Int 2022; 39:35. [PMID: 36469123 DOI: 10.1007/s00383-022-05331-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 11/30/2022] [Indexed: 12/12/2022]
Abstract
PURPOSE Screening for undescended testis (UDT) in Japan is performed as a neonate, then at 1, 3, 10, and 18 months old, and 3 years old. Incidence of ascending testis (AT) after screening was reviewed. METHODS All orchiopexy/orchiectomy at a single institute between July 2005 and June 2022 were reviewed retrospectively. RESULTS 376 boys had 422 procedures; 54/422 (12.8%) were in 48 boys ≥ 4 years old (mean age: 6.7 years; range: 4-13); testes were normal (n = 22; 40.7%), small (n = 25; 46.2%), or atrophied (n = 7; 1.3%). There were 47 orchiopexies and 7 orchiectomies for atrophy. Incidence of AT in boys ≥ 4 years old was 24/422 (5.7%). Of these, 16/422 (3.8%) developed after normal descent and 8/422 (1.9%) were associated with retractile testis (AT + RET). Other indications included delayed treatment for UDT (n = 13), late referral by pediatricians (n = 10), and iatrogenic UDT (n = 6). Surgical intervention in boys ≥ 4 years old (12.8%) was less than that reported in the West (range: 30-50%) as was AT: (5.7% versus 15.4%) and AT + RET (1.9% versus 13.8%). CONCLUSIONS Comprehensive UDT screening probably contributed to the lower incidence of surgery and AT (especially AT + RET) in boys ≥ 4 years old.

Abstract
Undescended testis (UDT) affects 6% of male births. Despite surgical correction, some men with unilateral UDT may experience infertility with the contralateral descended testis (CDT) showing no A-dark spermatogonia. To improve our understanding of the etiology of infertility in UDT, we generated a novel murine model of left unilateral UDT. Gubernaculum-specific Wnt4 knockout (KO) mice (Wnt4-cKO) were generated using retinoic acid receptor β2-cre mice and were found to have a smaller left-unilateral UDT. Wnt4-cKO mice with abdominal UDT had an increase in serum follicle-stimulating hormone and luteinizing hormone and an absence of germ cells in the undescended testicle. Wnt4-cKO mice with inguinal UDT had normal hormonal profiles, and 50% of these mice had no sperm in the left epididymis. Wnt4-cKO mice had fertility defects and produced 52% fewer litters and 78% fewer pups than control mice. Wnt4-cKO testes demonstrated increased expression of estrogen receptor α and SOX9, upregulation of female gonadal genes, and a decrease in male gonadal genes in both CDT and UDT. Several WNT4 variants were identified in boys with UDT. The presence of UDT and fertility defects in Wnt4-cKO mice highlights the crucial role of WNT4 in testicular development.

Contralateral testicular hypertrophy is associated with a higher incidence of absent testis in children with non-palpable testis. J Pediatr Urol 2022; 19:214.e1-214.e6. [PMID: 36460587 DOI: 10.1016/j.jpurol.2022.11.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Revised: 11/07/2022] [Accepted: 11/08/2022] [Indexed: 11/15/2022]
Abstract
BACKGROUND AND OBJECTIVE The objective of our study is to examine the impact of monorchism on contralateral testicular size in children with non-palpable testis (NPT). Enhanced contralateral testicular volume or longitudinal diameter (length) serves as a predictor of monorchism. In the present study, we assessed the ability of ultrasound measured enlarged contralateral testicular length for predicting monorchism (and hence a testicular nubbin) in children with NPT. Furthermore, we evaluated the general prevalence of viable versus non-viable testes in patients referred to our institution with unilateral undescended testis between 2005 and 2020. STUDY DESIGN We analysed the records of 54 patients who underwent diagnostic laparoscopy for NPT between 2005 and 2020 in a European tertiary care centre. Testicular lengths (longitudinal diameter) and testicular volume of the contralateral testis, as well as surgeon (surgeon 1 vs surgeon 2 vs others) and age at surgery (months) were assessed and stratified according to intraoperative findings (presence or absence of a testicular nubbin). Testicular length and volume were evaluated by ultrasound examination in office prior to surgery. Chi-square and t-test for descriptive analyses as well as uni- and multivariable logistic regression analyses were performed using R Version 3.1.0 (R Project for Statistical Computing, www.R-project.org). RESULTS A total of 15 children presented with viable testes and 39 patients with testicular nubbin. Mean age was 20.5 months in the overall cohort and 22.6 vs 19.7 months in children with viable testis vs testicular nubbin (p = 0.4). In patients with presence of a testicular nubbin, the contralateral testis was larger (median length 17 mm (16-19.2)) as compared to patients with a viable testis (median length 15 mm (14-17), p = 0.001). Similarly, contralateral testicular volume was lower in patients with a present viable testis (0.6 ccm vs 0.8 ccm; p < 0-001). This effect remained statistically significant when logistic regression analyses were adjusted for age and weight at surgery, year of surgery, surgeon, and laterality. OR (odds ratio) for presence of a testicular nubbin was 1.6 (per mm) [95% CI (confidence interval) 1.13-2.17; p = 0.007]. CONCLUSION Patients with preoperative increased length and volume of the contralateral testis in the ultrasound examination are at significantly higher risk of monorchism than their counterparts with lower testicular length. This should be emphasized during counselling of the parents prior to surgery. In our experience parents cope more easily with the diagnosis of monorchism, once this has already been discussed and explained thoroughly prior to surgery.

16 years follow-up evaluation of immediate vs delayed vs. combined hormonal therapy on fertility of patients with cryptorchidism: results of a longitudinal cohort study. Reprod Biol Endocrinol 2022; 20:102.

Abstract
BACKGROUND To investigate in a longitudinal cohort study, the best treatment to preserve fertility in cryptorchid subjects. Patients treated with immediate hormonal vs. delayed vs. combined (hormone plus surgery) therapy consecutively enrolled during the period 1987-1997, were evaluated. METHODS Two hundred fifty-five subjects were enrolled and 192 patients completed the follow-upt. One hundred fifty-six patients and 36 out 192 had monolateral and bilateral cryptorchidism, respectively. Twenty-nine out of 192 were previously treated by surgery alone (Group A), 93/192 by hormone therapy alone (Group B), 51/192 received sequential combined hormone therapy plus surgery (Group C) whilst 19/192 refused any type of treatment (Group D). The other 63 patients were considered lost to follow-up. All the patients underwent medical consultation, scrotal ultrasound scan, sperm analysis and Inhibin B, Follicular Stimulating Hormone (FSH) and Testosterone (T) serum level determination. RESULTS Testicular volume was found decreased in the Group D patients whilst hormone serum levels were comparable in all groups. Statistically significant differences for sperm characteristics were found in patients treated with hormonal therapy alone or combined with surgery (Groups B and C). These two groups reported better semen quality than patients who received surgery alone or no treatment. No differences were observed between monolateral and bilateral cryptorchidism patients. CONCLUSIONS Early prolonged hormonal therapy is advisable in all patients with cryptorchidism independently from the surgical option of promoting testicular descent to the scrotum. Hormonal therapy provides in our study better chance to obtain adequate sperm quality in adult life.

Prevalence, management, and outcome of cryptorchidism associated with gastroschisis: A systematic review and meta-analysis. J Pediatr Surg 2022; 57:1414-1422. [PMID: 34344532 DOI: 10.1016/j.jpedsurg.2021.07.006] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2021] [Revised: 06/06/2021] [Accepted: 07/05/2021] [Indexed: 11/17/2022]
Abstract
PURPOSE Cryptorchidism associated with gastroschisis has been poorly investigated. We aimed to assess the prevalence of this association, and to address the management and outcome of cryptorchidism in this context. MATERIALS AND METHODS In this systematic review, we searched electronic databases (PubMed, Web of Science, and Google Scholar), without language restrictions from inception to March 31, 2021, for studies on cryptorchidism and gastroschisis co-occurrence. Random effects meta-analysis was used to calculate pooled prevalence estimates of cryptorchidism in gastroschisis and spontaneous testicular descent in this population. RESULTS Twenty-five studies were included for the systematic review. All were retrospective case reports or series for a total of 175 patients. Pooled prevalence estimate for cryptorchidism in gastroschisis was 19% (95% CI 13-26). Complete data sets for management and outcome analysis were available in 94 patients, involving 120 undescended testes [63 (52.5%) nonpalpable, 34 (28.3%) prolapsed outside the abdominal wall defect, and 23 (19.2%) palpable]. Fifty-five descended spontaneously, with a pooled prevalence estimate of 50% (95% CI 31-69). Twelve testes/remnants were primarily removed or absent, while 49 testes underwent orchiopexy (success rate, 63%). Excluding 4 testes still awaiting orchiopexy, 30 of the remaining 116 (25.8%) testes had a dismal outcome, including testicular loss (19), hypoplasia (8) or recurrent cryptorchidism (3). CONCLUSION Cryptorchidism in gastroschisis appears to occur more frequently than in the normal population. The overall mediocre testicular outcome seems to reflect the most unfavorable presentation of cryptorchidism in gastroschisis, which is represented by originally intrabdominal or prolapsed testis in the majority of cases.

Abstract
Undescended testis (UDT) is defined as failure of a testis to descend into the scrotum. It is one of the most common reasons for consultation in pediatric surgery and urology with an incidence of 3% in live-born male infants. Decades ago, classical studies established that the failure of a testis to descend alters the development of its germ cells increasing the risk of infertility and testicular cancer in adulthood. More recent publications have rebutted some of the myths and raised controversies regarding the management of these patients, which, far from being limited to surgical treatment, should include pathophysiological and prognostic aspects for a comprehensive approach to the condition. Therefore, here we present an updated review divided into two parts: the first assessing the pathophysiological aspects and risks of these patients focused on fertility and cancer, and the second addressing the different treatment options for UDT.

Abstract
Undescended testis (UDT) is defined as failure of a testis to descend into the scrotum and it is a common reason for consultation in pediatric urology. As extensively discussed in "The undescended testis in children and adolescents: part 1", the failure of a testis to descend alters testicular germ-cells development, increasing the risk of infertility and testicular cancer in adulthood. Here, we present the second part of our review and analysis of this topic with the aim to propose an updated and well-informed approach to UDT together with a treatment flow chart that may be useful to guide pediatric surgeons and urologists in the care of these patients. The main goal of the management of patients with UDT is to diminish the risk of infertility and tumor development and is based on the clinical findings at the time of diagnosis.

Abstract
BACKGROUND/PURPOSE What causes normal descent of the testis in a fetus, and what goes wrong with this complex process to cause undescended testes (UDT), or cryptorchidism? Over the last 2 decades, most authors searching for the cause(s) of UDT have looked at the 2 main hormones involved, insulin-like hormone 3 (Insl3) and testosterone (T)/ dihydrotestosterone (DHT), and their known upstream (hypothalamic-pituitary axis) and intracellular 'downstream' pathways. Despite these detailed searches, the genetic causes of UDT remain elusive, which suggest the aetiology is multifactorial, and/or we are looking in the wrong place. METHODS In this review we highlight the intricate morphological steps involved in testicular descent, which we propose may contain the currently 'idiopathic' causes of UDT. By integrating decades of research, we have underlined many areas that have been overlooked in the search for causes of UDT. RESULTS It is quite likely that the common causes of UDT are still hidden in these areas, and we suggest examining these processes is worthwhile in the hope of finding the common genetic anomalies that lead to cryptorchidism. Given the fact that a fibrous barrier preventing descent is often described at orchidopexy, examination of the extracellular matrix enzymes needed to allow gubernacular migration may be a fruitful place to start. CONCLUSION This review of the complex anatomical steps and hormonal regulation of testicular descent highlights many areas of morphology and signalling pathways that have been overlooked in the search for causes of UDT.

Abstract
OBJECTIVE To determine the impact of orchiopexy on testicular volume. To determine whether age at surgery impacts testicular volume. To determine whether paternity is associated with testicular volume. METHODS Patients born between 1961 and 1985 who had undergone cryptorchidism surgery at the Pediatric Surgery Department of Miguel Servet University Hospital were included. Testis location and macroscopic appearance data were collected. Control testicular ultrasonographies and paternity surveys were carried out. Initially, the study was descriptive, and subsequently, inferential. RESULTS Ultrasonography was performed in 216 testicular units a mean of 14.9 years following surgery, whereas the paternity survey was conducted among 157 respondents a mean of 41.9 years following surgery. There were significant differences (p = 0.0038) in testicular volume distribution according to epididymal dissociation. There was a linear correlation between older age at surgery and lower testicular volume, but without statistical significance. Significant differences (p < 0.0001) in testicular volume according to groups - operated and non-operated -, as well as between unilateral and bilateral cases, were found. No differences in paternity rates according to testicular volume were noted. CONCLUSION Operated testes have lower volumes than normally descended testes. Older age at surgery may contribute to lower final volumes. Testes with full epididymal-testicular dissociation have lower total volumes. No relation between testicular volume and paternity rates was found. Further long-term studies are required.

Abstract
BACKGROUND Little is known about the timeframe in which acquired undescended testes occur. To guide recommendations for screening examinations, we aimed to (1) specify the ratio of acquired undescended testes in orchiopexy cases and to (2) identify a predisposing age for the development of acquired undescended testis. METHODS Three-hundred-forty cases of orchiopexy were retrospectively analyzed and classified as congenital or acquired cases of undescended testis. In acquired cases, the time of the last documented physiological testicular position was obtained. The time of testicular ascent was approximated by calculating the mean between the last physiological finding and orchiopexy. RESULTS In 151 cases (44.4%) prior physiological position of testes was documented and acquired undescended testis was assumed. In 115 of these cases (76.2%) details on the age at last physiological position were available. Ascent occurred between the age of one and fourteen. The 50th, 75th, 85th, 90th and 95th percentile for the estimated age at ascent was 5.8, 7.3, 8.4, 8.7 and 11.1 years, respectively. CONCLUSIONS Acquired undescended testes are a common cause of cryptorchidism. Ascent occurs throughout all prepubertal ages, emphasizing the need to regular follow-up of testicular position until puberty. TYPE OF STUDY Prognosis study. LEVEL OF EVIDENCE Level II.

[PMID: 34631427 PMCID: PMC8488486 DOI: 10.1016/j.eucr.2021.101853] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2021] [Revised: 09/09/2021] [Accepted: 09/11/2021] [Indexed: 11/16/2022] Open
Abstract
Early diagnosis of undescended testis (UDT) in patients under 2 years old plays a vital role in therapy success. However, in developing countries, UDT is often diagnosed in over 2 years. This case report described unilateral UDT in a patient aged 19 years accompanied by testicular torsion, which was found intraoperatively and not vital. Thus, the operator decided to do an orchiectomy. The operation was successful, and the patient was discharged the day after the surgery.

A rare familial rearrangement of chromosomes 9 and 15 associated with intellectual disability: a clinical and molecular study. Mol Cytogenet 2021; 14:47. [PMID: 34607577 PMCID: PMC8489072 DOI: 10.1186/s13039-021-00565-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2021] [Accepted: 03/09/2021] [Indexed: 11/22/2022] Open
Abstract
Background There are many reports on rearrangements occurring separately in the regions of chromosomes 9p and 15q affected in the case under study. 15q duplication syndrome is caused by the presence of at least one extra maternally derived copy of the Prader–Willi/Angelman critical region. Trisomy 9p is the fourth most frequent chromosome anomaly with a clinically recognizable syndrome often accompanied by intellectual disability. Here we report a new case of a patient with maternally derived unique complex sSMC resulting in partial trisomy of both chromosomes 9 and 15 associated with intellectual disability. Case presentation We characterise a supernumerary derivative chromosome 15: 47,XY,+der(15)t(9;15)(p21.2;q13.2), likely resulting from 3:1 malsegregation during maternal gametogenesis. Chromosomal analysis showed that a phenotypically normal mother is a carrier of balanced translocation t(9;15)(p21.1;q13.2). Her 7-year-old son showed signs of intellectual disability and a number of physical abnormalities including bilateral cryptorchidism and congenital megaureter. The child’s magnetic resonance imaging showed changes in brain volume and in structural and functional connectivity revealing phenotypic changes caused by the presence of the extra chromosome material, whereas the mother’s brain MRI was normal. Sequence analyses of the microdissected der(15) chromosome detected two breakpoint regions: HSA9:25,928,021-26,157,441 (9p21.2 band) and HSA15:30,552,104-30,765,905 (15q13.2 band). The breakpoint region on chromosome HSA9 is poor in genetic features with several areas of high homology with the breakpoint region on chromosome 15. The breakpoint region on HSA15 is located in the area of a large segmental duplication. Conclusions We discuss the case of these phenotypic and brain MRI features in light of reported signatures for 9p partial trisomy and 15 duplication syndromes and analyze how the genomic characteristics of the found breakpoint regions have contributed to the origin of the derivative chromosome. We recommend MRI for all patients with a developmental delay, especially in cases with identified rearrangements, to accumulate more information on brain phenotypes related to chromosomal syndromes.

Abstract
INTRODUCTION Splenogonadal fusion is a rare congenital anomaly of unknown etiology caused by an abnormal fusion of the splenic tissue and the gonadal tissue. CASE REPORT 2-year-old patient with paralysis of the 6th, 7th, and 9th cranial nerves, tent-shaped mouth, cleft palate, right pectoralis major hypoplasia, disruptive defect of the right upper limb, and a mass located at the left inguinal region. At inguinal hernia repair surgery, a processus vaginalis with non-reducible content was observed. When opening the hernia sac, a descending segment of splenic tissue merging with the upper pole of the left testis was found. The patient was diagnosed with splenogonadal fusion. The splenic tissue merging with the testis upper pole was resected, and the remaining splenic tissue was reduced towards the abdominal cavity. DISCUSSION Splenogonadal fusion is difficult to diagnose. Being familiar with it allows unnecessary orchiectomies to be prevented.

Ascending testis: A congenital predetermined condition. J Pediatr Urol 2021; 17:192.e1-192.e3. [PMID: 33483293 DOI: 10.1016/j.jpurol.2020.12.016] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2020] [Revised: 12/11/2020] [Accepted: 12/16/2020] [Indexed: 11/21/2022]
Abstract
INTRODUCTION About 0.8% of boys have undescended testes at 1 year of age. However, the overall rate of orchidopexy is 2.5 times that expected. While studies have shown ascending testes accounting for a proportion of such discrepancy, the aetiology of this ascent remains controversial. In this study, intra-operative findings of patients underwent orchidopexy for ascending testes are evaluated to infer aetiology. METHODS Patients with confirmed ascending testes from a single paediatric surgery unit over a four-year period from June 2015 till June 2019 were included in this observational study. During orchidopexy procedure, intra-operative findings in terms of gubernacular attachment, and the degree of epididymal attachment to the upper pole of the testicle were primarily evaluated. Secondary findings including the presence and length of patent processus vaginalis (PPV), and the presence of any long looping vas or hydatid of morgangi were also noted. RESULTS Eighty-three children (median age = 79 months [range 38-149]) were included in this study. Two boys had bilateral ascending testes leading to a total of 85 orchidopexy cases performed. All patients were found to have a gubernacular attachment proximal to the junction between the upper lateral wall of scrotum and the medial part of the thigh. PPV was present in all cases, with its length measured from the deep inguinal ring after retracting the conjoint tendon ranging from 4 to 15 mm 84 cases (98.8%) demonstrated complete or partial separation between the head of epididymis and the upper pole of the testicle. Hydatid of morgagni was present in 82 cases (96.4%), and none of the operated testicles demonstrated looping vas. DISCUSSION The varying degrees of PPV length demonstrated during orchiodpexy for ascending testes in this study casts a doubt on the role of processus vaginalis in such ascent. Also, there is considerably a wide-range of reported incidence (13-78%) in literature for PPV in ascending testes. In this study, intra-operative findings demonstrated an abnormal gubernaculum attachment in all ascending testes in keeping with previous reports, and support the hypothesis that ascending testis has always been undescended, yet acquired more apparent undescended position with child age and growth. CONCLUSION Patients with ascending testes seem to share similar intra-operative findings with patients who have true undescended testes. The universal abnormal attachment of the gubernaculum and the omnipresent testicular-epididymal fusion anomalies may indicate that ascending testis is a congenital predetermined condition, and that these testes have always been congenitally undescended, yet obtained a more noticeable position with the child growth.

A narrative review of the history and evidence-base for the timing of orchidopexy for cryptorchidism. J Pediatr Urol 2021; 17:239-245. [PMID: 33551366 DOI: 10.1016/j.jpurol.2021.01.013] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/06/2020] [Revised: 01/12/2021] [Accepted: 01/14/2021] [Indexed: 11/26/2022]
Abstract
INTRODUCTION Consensus recommendations for surgical management of cryptorchidism recommend orchidopexy between 6 and 18 months of age. The COVID-19 pandemic has impacted elective surgical scheduling. OBJECTIVE In response to the COVID-19 pandemic, we sought to review the available data regarding the natural history, surgical management, and infertility- and cancer-related risks associated with cryptorchid testes. The purpose of this review is to provide parents, referring providers, and surgeons with information to inform their decisions to proceed with or delay orchidopexy. METHODS A retrospective review and analysis of all available articles relevant to the natural history, surgical management, and infertility- and cancer-related risks of cryptorchidism present on PubMed, SCOPUS, and Cochrane Library was conducted. RESULTS The quality of historic literature pertaining to the effect of cryptorchidism on fertility and malignancy differ, with poorer data available on fertility. Cryptorchid testes may show histologic differences as early as birth, and some of these changes may have prognostic value in future fertility. Formerly unilateral cryptorchid men have slightly but not significantly reduced paternity rates compared to the general population. Cryptorchid testes have an increased risk of germ cell carcinogenesis, and robust data suggest the risk for malignancy in cryptorchid testes increases substantially after puberty. CONCLUSION The current body of evidence regarding the risks for future infertility and testicular cancer support the consensus recommendations for surgical correction of cryptorchidism between 6 and 18 months of age. During the uncertain time of the COVID-19 pandemic, decision for orchidopexy is a shared-decision between physician and parent. For an infant or young boy with a unilateral undescended testes, delaying orchidopexy several months until a time of decreased exposure risk is unlikely to result in substantial or sustained fertility or malignant risks.

Ruptured intra-abdominal testicular seminoma with hemorrhage shock, after inadequate surgical exploration for undescended testis: a case report. Surg Case Rep 2021; 7:65. [PMID: 33683491 PMCID: PMC7940457 DOI: 10.1186/s40792-021-01143-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Accepted: 02/22/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Undescended testes are associated with an increased risk of malignancy and infertility, and surgical treatment in childhood is recommended. CASE PRESENTATION A 35-year-old man presented to the emergency department with abdominal pain and vomiting. Despite a history of surgery for a left undescended testis in infancy, his left-sided scrotum appeared underdeveloped. Contrast-enhanced computed tomography showed a pelvic mass, involving a major axis of approximately 15 cm, with high-density ascites suggestive of hemorrhage. A ruptured gastrointestinal stromal tumor was suspected. As he was in hemorrhagic shock, an emergency laparotomy was indicated. The active bleeding mass was controlled through complete resection. A pathological evaluation of the mass revealed a seminoma arising from an undescended testis. His post-operative course was uneventful, and he was discharged on post-operative day 6. Recurrence on the retroperitoneal lymph nodes was detected 1 year postoperatively, and a retroperitoneal lymph node dissection was performed after chemotherapy. He remains well without any apparent signs of recurrence. CONCLUSIONS Paying close attention to an empty scrotum is advisable, even postoperatively, for undescended testis because of possible subsequent potential malignancy presenting with hemorrhage, as our patient demonstrated.

Abstract
INTRODUCTION Undescended testes present in 3-5% of male infants at birth. Orchidopexy is indicated to improve fertility and reduce the risk of testicular tumors. Guidelines recommend orchidopexy as early as six months of age, treatment should be finished within the age of 18 months. So far, no unequivocal proof demonstrated the superiority of one of the different surgical techniques. OBJECTIVE To evaluate the value of an additional scrotal suture between the tunica albuginea and the dartos fascia during orchidopexy in an outpatient setting. It is yet unclear, whether the suture influences the incidence of secondary cryptorchidism or recurrence. STUDY DESIGN This is a retrospective cohort study. Between 2010 and 2018 two experienced surgeons performed 561 inguinal orchidopexy-procedures in an open technique (375 boys). In group 1 (2010-2014) they managed 234 IOP (156 boys) without an additional scrotal suture. Since 2014, in group 2 an additional suture has been performed in 327 IOP (219 boys). Statistically, we compared both groups over a period of consecutive 4 years after the model of a life table analysis (Logrank). RESULTS The numbers of boys with complete follow-up were 118 of 156 in group 1 and 154 of 219 in group 2, demonstrating 7 (5.9%) and 7 (4.5%) recurrences, respectively. There was no statistically significant difference in recurrences between group 1 and group 2 (Logrank-Test, p = 0.97). Orchidopexie failure was detected between 0.9 and 23.1 months after the IOP in group 1 and between 3.2 and 17.7 months in group 2. Mean age in months at the operation in both groups was significantly higher than the recommended 6-18 months in the EAU/AUA-guidelines. Both groups showed similar rates of postoperative complications. DISCUSSION Orchidopexy is a safe procedure in an outpatient setting. So far there is no evidence that performing an additional scrotal suture decreases the operative failure rate in inguinal standard orchidopexy procedures.

Abstract
Cryptorchidism is one of the most common congenital anomalies of the genitourinary tract, encountered in 1% of men. The cancer risk in an ectopic testis is 40 times higher than a scrotal testis. However, not much literature is available on the management of this rare presentation of testicular cancer. A retrospective analysis was conducted at our institute of patients who were diagnosed with carcinoma in an undescended intra-abdominal testis between 2014 and 2019. Patients with an intra-abdominal mass with an empty hemiscrotum/scrotum were included in the study. In all 10 patients were identified with a mean age of 32 years. Four patients were non-seminomatous germ cell tumors, and other 6 were seminomatous tumors. Five were in stage I, two in stage II, and three in stage III. Six patients received induction chemotherapy with bleomycin, etoposide, and cisplatin, and four had complete response. Five patients underwent laparoscopic excision, and five underwent open surgery. Two patients with bilateral (B/L) cryptorchidism underwent contralateral orchidopexy. Two patients with B/L intra-abdominal gonads and uterus underwent excision of the malignant testicular mass with removal of atrophic uterus and contralateral dysgenetic gonad. One patient developed peritoneal recurrence within 3 months of completion of surgery. Both recurrence-free and overall survival were 90% after a median follow-up of 35 months. Malignancy in an undescended intra-abdominal testis is a rare presentation of testicular cancer, diagnosis of which requires a sharp correlation between clinical and radiological findings. There management and prognosis remains similar to classical testicular cancer.

Abstract
INTRODUCTION Polyorchidism is a rare congenital malformation with about 200 cases reported in literatures. Triorchidism and left side occurrence are the most common presentation. This case report was aimed to report the rare presentation of polyorchidism which was on the right side and along with incarcerated inguinal that make it by far the least encountered presentation. The intraoperative management for the polyorchidism was an issue of dilemma but adult type can be excised safely. PRESENTATION OF THE CASE A 43 year old farmer presented with right side inguino-scrotal mass and recent failure to reduce to abdomen. He used to have pain lower abdominal pain with slight pressure since childhood but didn't get any medical evaluation. He has completed his family number and didn't complain any sexual problem. Physical examination showed that there was non-tender irreducible soft right side inguino-scrotal mass. The right side testis was not appreciated. DISCUSSION Triorchidism is one of the commonly occurring variant of supernumerary testes that diagnosed incidentally during investigations or interventions for other pathologies. Incarcerated inguinal hernia masks its detection on physical examinations, so its diagnosis is more of intraoperative making a one time management for both pathologies at single operation especially if the operation undertake with general anesthesia. This patient was operated for incarcerated inguinal hernia with incidental finding of right side type B1 polyorchidism. Both of the right side testes were atrophic and excision was done. CONCLUSION Patients who present at a late adulthood age with polyorchidism and undescended testis can be successfully treated with surgical removal of the atrophic supernumerary testes.

Abstract
Cryptorchidism (CO) is a genital disorder of multifactorial etiology, with serious remote complications. Mutations in insulin-like 3 hormones (INSL3) G/A variant remain a matter of inquiry. We aimed to investigate the association between G178A-INSL3 polymorphism and undescended testis in a cohort of Egyptian children. In this study, a total of 160 children, including 80 cases with primary non-syndromic undescended testes and 80 healthy children with normal external genitalia as controls, both, were analyzed after detailed history, physical examination and imaging for mutations of G178A polymorphism of INSL3 gene by restriction fragment length polymorphism (RFLP) technique. We found most of the undescended testes were inside the inguinal canal mainly on the left side. Genetic analysis revealed that the mutant A allele of G178A INSL3 variant was significantly detected in the patient group with a frequency of 26.2% against 12.5% for control subjects, especially among cases with an evident family history of similar cases as shown by p value = 0.001 and odd's ratio (CI95%) of 0.13 (0.04-0.723). In conclusion, G178A-INSL3 gene polymorphism could be a susceptibility factor for testicular maldescent in Egyptian children. Also, family history of similar cases was considered as significant predictive risk for cryptorchidism, added to the shared genetic links to consanguinity in our locality.

Testicular hypertrophy as predictor of contralateral nonpalpable testis among Chinese boys: An 18-year retrospective study. Arch Pediatr 2020; 27:456-463. [PMID: 33011030 DOI: 10.1016/j.arcped.2020.08.006] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2019] [Revised: 06/28/2020] [Accepted: 08/24/2020] [Indexed: 11/24/2022]
Abstract
OBJECTIVE To assess the accuracy of contralateral testis hypertrophy for predicting the fate of nonpalpable testis in Chinese boys at different ages. METHODS The data of patients who presented with unilateral impalpable testis and who underwent laparoscopy at the Children's Hospital of Chongqing Medical University between January 1, 2000 and January 1, 2018 were reviewed. The boys were divided into four groups: age-matched volunteers with no testicular abnormalities represented the control group (group I), boys with palpable undescended testis (group II), boys with nonpalpable testis (NPT)/viable testis (VT) (group III), and boys with NPT/non-viable testis (NVT) group (group IV). Scrotal testes were prospectively measured by ultrasonography for volume and size, and diagnostic laparoscopy was performed to determine the state of the cryptorchid testis. RESULTS The mean contralateral testicular volume and length in the boys with an absent testis was 0.78mL and 17mm compared with 0.67mL and 15mm in the boys with a testis present and 0.63mL and 15mm in the controls, respectively (P<0.05). The predictive accuracy, sensitivity, and specificity for an absent testis were 64.9%, 75%, and 49%, respectively, for volume and 64.2%, 56.3%, and 76.4%, respectively for length at the optimal cutoff value of 0.65mL volume and 16.55mm length. Contralateral testis volume was the most accurate in predicting monorchism in 0-2-year-olds (sensitivity: 75%, specificity: 70%, accuracy: 73.1%) and the contralateral testicular length was most accurate for 4-6-years-old (sensitivity: 68.6%; specificity: 77.8%; accuracy: 72.2%). We also included 29 patients with bilateral undescended testis (UDT) and with unilateral nonpalpable. Cutoff values for testicular volume and length were 0.6mL (sensitivity: 81.8%, specificity: 88.9%, accuracy: 86.2%) and 13.5mm (sensitivity: 63.6%, specificity: 77.8%, accuracy: 77.8%). CONCLUSION The present results exclusively obtained from laparoscopic exploration suggest that a testis volume of>0.65mL or a testis length of>16.55mm could predict monarchism with an accuracy of about 65%. In younger patients aged 0-2 years and 4-6 years, the overall predictive accuracy increases to about 73% but laparoscopic exploration is still required.

Cryptorchidism, gonocyte development, and the risks of germ cell malignancy and infertility: A systematic review. J Pediatr Surg 2020; 55:1201-1210.

Abstract
BACKGROUND/AIM Cryptorchidism, or undescended testis (UDT) occurs in 1%-4% of newborn males and leads to a risk of infertility and testicular malignancy. Recent research suggests that infertility and malignancy in UDT may be caused by abnormal development of the neonatal germ cells, or gonocytes, which normally transform into spermatogonial stem cells (SSC) or undergo apoptosis during minipuberty at 2-6 months in humans (2-6 days in mice). We aimed to identify the current knowledge on how UDT is linked to infertility and malignancy. METHODS Here we review the literature from 1995 to the present to assess the possible causes of infertility and malignancy in UDT, from both human studies and animal models. RESULTS Both the morphological steps and many of the genes involved in germ cell development are now characterized, but the factors involved in gonocyte transformation and apoptosis in both normal and cryptorchid testes are not fully identified. During minipuberty there is evidence for the hypothalamic-pituitary axis stimulating gonocyte transformation, but without known direct control by LH and androgen, although FSH may have a role. An arrested gonocyte maybe the origin of later malignancy at least in syndromic cryptorchid testes in humans, which is consistent with the recent finding that gonocytes are normally absent in a rodent model of congenital cryptorchidism, where malignancy has not been reported. CONCLUSION The results of this review strengthen the view that malignancy and infertility in men with previous UDT may be caused by abnormalities in germ cell development during minipuberty.

Torsion of an undescended testis - A surgical pediatric emergency. J Pediatr Surg 2020; 55:660-664.

Abstract
BACKGROUND/PURPOSE Torsion of an undescended testis is a surgical emergency whose frequency may be underestimated in the pediatric population. We describe this entity and focus on diagnostic challenges and optimal treatment of torsion of an undescended testis. METHODS We present a two-center retrospective chart review of patients with torsion of an undescended testis treated between 2013 and 2018. Two instructive cases are used to depict characteristics of this rare entity. RESULTS We identified 11 patients with previously diagnosed cryptorchidism undergoing surgery for torsion of an undescended testis, accounting for 9.7% (11/107) of all testicular torsions in the period. Mean age at diagnosis was 9.4 months (1-22 months). Mean duration from onset of symptoms to presentation was 19.3 h (8-48 h). At admission to hospital 10 patients presented with groin lump (10/11, 90.9%) with or without pain leading to a suspected diagnosis of inguinal testicular torsion (5/11, 45.5%), incarcerated inguinal hernia (4/11, 36.4%) and epididymitis (1/11, 9.1%). Ten patients had an ultrasound examination before surgery leading to the correct diagnosis in six patients. Ultrasound findings were misinterpreted as incarcerated inguinal hernia in three patients. In eight patients the testis had to be removed at time of surgery; one of the three salvaged testes atrophied, resulting in a salvage rate of 18%. CONCLUSION Torsion of an inguinal testis is not as rare as it might be presumed. Presentation of these patients is often deferred owing to equivocal signs and symptoms. In addition age at presentation differs from typical testicular torsion. As this might negatively influence testicular salvage rate, we advocate for special attention to this differential diagnosis in children with groin pathologies. Even if the child is not in pain, a tender groin in boys with undescended testes must prompt a quick and thorough examination to rule out torsion of an undescended testis. Ultrasound examination is of limited value and must not delay acute surgical treatment. LEVEL OF EVIDENCE IV.

Abstract
INTRODUCTION Cryptorchidism is defined as the absence of one or both testicles from the scrotum, which is considered one of the most common birth defects of male genitalia. Mostly the undescended testes are in the inguinal region, while the intra-abdominal location accounts for only 10 % of the cases. The potential risk of malignant transformation in an undescended testis is approximately 2.5-8 times higher than in scrotal position. Torsion of the cryptorchid testis is a very rare cause of acute abdominal pain with few cases published in literature. CASE PRESENTATION A 44-year-old male patient presented to the emergency room with acute abdominal pain. General examination revealed relevant tachycardia. Upon abdominal examination there was tenderness and rebound tenderness all over the abdomen, more evident in the lower abdomen. Interestingly, routine examination of the inguino-scrotal region revealed empty right hemi-scrotum despite the patient not being aware. Routine blood tests showed marked anemia Hb: 7.4 g/dl. Urgent pelvi-abdominal U/S showed moderate free intra-abdominal collection in addition to a pelvic mass. CT of the abdomen showed a well-defined heterogenous hypodense mass measuring about 8.5 × 5.5 cm in the pelvis. Urgent exploratory laparotomy was done, and a mass was found to be torted and ruptured. Excision was done and histo-pathological examination revealed testicular mixed germ cell tumor. CONCLUSION Undescended testis is associated with an increased risk of infertility, testicular cancer and torsion. In any male with undescended testis and intra-abdominal mass; the risk of intra-abdominal testicular tumor should be considered.

Abstract
It has been known for more than 20 years that early treatment of maldescended testicles can have a positive effect on fertility and a negative effect on the development of tumors. In certain circumstances, hormone therapy is still recommended in German-speaking countries. However, its benefit is still controversially discussed. Therapy is usually initiated by the pediatrician, who is usually the first to detect undescended testicles. Since therapy may involve early hormone therapy as well as surgery, acceptance among pediatricians and also the parents may be reduced. The question also arises as to how far the implementation is practicable. In patients with nonpalpable testis, there are many controversies concerning the value of ultrasound investigations. In the following two case studies, the treatment decisions for undescended testes in infancy are exemplified. Furthermore, the available evidence from the literature and guidelines is presented to provide assistance for daily routine care and to critically discuss potential fields of application and limitations of existing guidelines.

The occurrence of an additional (accessory) lobe of liver and undescended testis in a single cadaver: a case report. J Med Case Rep 2019; 13:357. [PMID: 31806047 PMCID: PMC6896681 DOI: 10.1186/s13256-019-2294-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2019] [Accepted: 10/15/2019] [Indexed: 02/08/2023] Open
Abstract
Background Anatomical variations are common, some of these variations are clinically important and some are not. These variations may require treatment or they may be a variant of a normal presentation. In clinical practices, anatomical variations should not be overlooked. Anatomical variations may cause a tendency to some diseases, and may affect the symptoms, diagnosis and the course of disease. The main objective of this case report is to present the occurrence of two variations observed in a single cadaver. Even though there are reports of individual cases, these combined variations have not been reported before. There is also no evidence of developmental (embryological) circumstances for the liver anomaly to be associated with an undescended testis (cryptorchidism) and vice versa; therefore, this case is, by far, a coincidence. Case presentation The two anatomical variations were noticed in an unclaimed male cadaver used for routine teaching and learning purposes. The Amhara male cadaver was approximate 41-year-old and his clinical history, family history, and other details were unknown. In the first incident, unusually the cadaver’s liver consisted of one additional (accessory) lobe situated on the visceral surface of the liver. In the second incident, an undescended testis was observed on the right side near to the superficial inguinal ring. Conclusions Overall, knowledge of the above-mentioned anatomical variations has clinical significance to students, researchers, clinicians, surgeons, and radiologists who interpret plain and computed imaging.

Abstract
TTE associated with PMDS is a rare case which is incidentally discovered during surgery of undescended testis. Early diagnosis and treatment is necessary to prevent malignancy. Follow-up for fertility assessment in the latter years should be counselled.
İntroduction Transverse testicular ectopia (TTE) is a rare anomaly characterized by the presence of both testicles in the same hemiscrotum or inguinal region. The most common clinical findings of TTE are unilateral nonpalpable testis in the scrotum and inguinal hernia on the side of palpable testis in the scrotum. It should be kept in mind that TTE may coexist with Persistent Mullerian Duct Syndrome (PMDS). Therefore, appropriate treatment should be performed considering PMDS. Presentation of case Type 2 transverse testicular ectopia was diagnosed in one patient who was operated with bilateral undescended testis. He was treated with transseptal orchiopexy and excision of mullerian structures. Discussion In case of TTE with PMDS, optimal surgical approach with orchiopexy and excision of Müllerian duct is necessary. Intraoperative aggressive dissection of vas deferens and testicular vessels should be avoided in TTE patients. They should be closely followed because of the increased risk of malignant transformation in the postoperative period. Conclusion An investigation of transvers testicular ectopia should be performed in all nonpalpable undescended testis anomalies.

Human chorionic gonadotrophin hormone for treatment of congenital undescended testis: Anatomical barriers to its success. J Pediatr Surg 2019; 54:2413-2415. [PMID: 30867099 DOI: 10.1016/j.jpedsurg.2019.01.067] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2018] [Revised: 12/19/2018] [Accepted: 01/27/2019] [Indexed: 01/06/2023]
Abstract
BACKGROUND/PURPOSE Although the surgical treatment was proved to be the recommended line of management for congenital undescended testis, hormonal therapy with human chorionic gonadotrophin hormone has been started long years ago and is still used in some areas with variable degrees of success. The factors responsible for treatment failure are not well explored. In this study, we aimed to highlight the anatomical abnormalities in the congenital undescended testis that might contribute to treatment failure. METHODS During the period from January 2014 to December 2015, 75 boys with congenital undescended testes received treatment with human chorionic gonadotrophin, in pediatric surgery department, Faculty of medicine, Ain Shams University. Their age ranged between 6 months and 4 years (mean 1.6 years, median 2 years). In 70 boys, the testes were palpable and in the remaining 5 boys, the testes were impalpable. Fifty boys had unilateral and 25 had bilateral undescended testes. Seven of the palpable testes were high scrotal in position and the remaining 83 were palpated in the inguinal canal. The patients were followed up for 6 months to determine the position of the testis after the treatment and surgical intervention was done for those who did not respond to the hormonal treatment either partially or completely. RESULTS Only 7 testes showed complete descent (7%) (2 bilateral and 3 unilateral) and they were initially high scrotal in position, 8 testes showed partial descent (8%) (2 bilateral and 4 unilateral) and they were inguinal in 6 which became high scrotal and impalpable in 2 which became peeping. The remaining 85 (85%) did not respond to the hormonal treatment. Upon surgical exploration, abnormal attachment of the gubernaculum was found in 83 testes (83%), 2 testes were peeping (2%), short testicular vessels were found in 4 testes (4%), 3 testes were vanishing (3%) and a closed internal ring was found in one testis (1%). CONCLUSIONS Treatment of congenital undescended testis with human chorionic gonadotrophin hormone had low success rates. Anatomical abnormalities in the congenital undescended testis might contribute to this treatment failure. TYPE OF THE STUDY Clinical research paper. LEVEL OF EVIDENCE level III.

Factors associated with delay in undescended testis referral. J Pediatr Urol 2019; 15:380.e1-380.e6.

Abstract
INTRODUCTION Undescended testis (UDT) is one of the most common congenital disorders and is associated with infertility and testicular cancer. Multiple guidelines internationally have recommended orchiopexy by 18 months. Multiple large retrospective studies published in the last decade have found persistent delay in timing of orchiopexy. OBJECTIVE The aim of the study was to determine timing at which UDTs are referred at the tertiary pediatric hospital and assess factors that are associated with delay in UDT referral. STUDY DESIGN Based on clinical observations and previous data, a series of clinical and socio-economic variables were constructed to design a prospective database. All patients who underwent orchiopexy for UDT from March 1, 2017, to August 31, 2018, were reviewed for demographic and clinical data. Referral appointments after 18 months were considered delayed. Factors associated with delay in UDT referral were analyzed using univariate and multivariate analysis with logistic regression. RESULTS One hundred seventy-eight patients underwent orchiopexy for UDT. The median age was 44 months, and 64% of them had delay in referral. On univariate analysis, normal birth testicular examination, diagnosis of 'retractile testicle,' long gap without seeing pediatrician, diagnosis by a new physician, and primary language non-English were associated with delayed UDT referral. On multivariate analysis, delayed referral was associated with normal testicular examination at birth, history of 'retractile testis,' diagnosis not by the regular primary care provider, and other health or social issues that may have led to delay. DISCUSSION This is the first prospective study analyzing timing of referral for boys with cryptorchidism. It was found that timing of treatment of UDT with orchiopexy has not improved over the last decade. Major causes in delay in referral may be due to poor of education of families and lack of routine testicular examinations by referring providers. Secondary ascent may account a significant number of delayed orchiopexy cases. CONCLUSION Most patients at Doernbecher had delayed referral of cryptorchidism. Factors associated with delay were determined. To improve treatment of cryptorchidism, quality-based interventions and the importance of education and routine testicular examinations need to be focused on.

Postnatal germ cell development during first 18 months of life in testes from boys with non-syndromic cryptorchidism and complete or partial androgen insensitivity syndrome. J Pediatr Surg 2019; 54:1654-1659. [PMID: 30739749 DOI: 10.1016/j.jpedsurg.2018.12.011] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/18/2018] [Revised: 11/28/2018] [Accepted: 12/18/2018] [Indexed: 11/15/2022]
Abstract
INTRODUCTION Neonatal testicular germ cells/gonocytes, transform into stem cells for spermatogenesis during 'minipuberty', driving change in timing of surgery. This study examined gonocyte transformation in cryptorchid testes in children ≤18 months of age with unilateral, bilateral undescended testes (UDT), complete or partial androgen insensitivity syndrome (CAIS, PAIS) [3,4]. MATERIAL AND METHODS Testicular biopsies were taken from patients with unilateral or bilateral UDT, PAIS or CAIS, aged 10 days-18 months. These testicular sections underwent immunohistochemistry with antibodies (Oct4, Ki67, C-Kit, Sox9) followed by confocal imaging, cell counting and statistical analysis. RESULTS Both Sertoli cells/tubule and germ cells (GC)/tubule decreased with age, and % empty tubules (no GC) increased with age but with no significant differences between patient groups. Oct4+ germ cells/tubule decreased with age. There are some GCs and Sertoli cells proliferating during the first year and most proliferating Oct4+ germ cells (Oct4+/Ki67+) were located off tubular basement membrane. CONCLUSION Our study showed that Oct4 expression gradually decreased after minipuberty and transformation into spermatogonia. Germ cells and Sertoli cells undergo mitosis during the first 12 months although not abundantly. We propose that Oct4+ gonocyte transformation into spermatogonia via proliferation and migration to the basement membrane may be delayed in UDT.

Abstract
Purpose The factors affecting spermatogenesis in adulthood in patients with hypospadias (HS) are not clearly understood. In the present study, risk factors affecting post-pubertal high serum follicle-stimulating hormone (FSH) were evaluated in patients with HS. Materials and methods Among those with a history of HS surgery, patients in whom endocrinological evaluation regarding pituitary–gonadal axis was performed at 15 years of age or older between March 2004 and April 2018 were enrolled in the present study. High serum FSH was defined as greater than 10 mIU/ml. The severity of HS was divided into mild and severe. Factors affecting the post-pubertal high serum FSH were estimated. Results Seventy-nine patients were included in the present study. The severity of HS was mild in 35 and severe in 44. History of undescended testis (UDT) was confirmed in 12. High serum FSH was detected in nine. On logistic regression model analysis, a history of UDT was the only significant factor for high serum FSH. The incidence of high serum FSH in patients with UDT was significantly higher than that in those without UDT (58.3% vs 7.5%, p < 0.01). When stratified by severity of HS and the presence of UDT, high serum FSH was detected in 70% in patients with severe HS and UDT, whereas less than 10% in other groups. Conclusions A history of UDT was a significant factor for post-pubertal high serum FSH in patients with HS. Accordingly, the presence of UDT may be a marker for impaired spermatogenesis in patients with HS, especially in severe cases.
