[PMID: 38686073 PMCID: PMC11056246 DOI: 10.1002/iju5.12720] [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: 12/27/2023] [Accepted: 02/27/2024] [Indexed: 05/02/2024] Open
Abstract
Introduction The development of malignant tumors in patients with hydranencephaly is extremely rare. We describe the first case of testicular cancer that developed in the undescended testes of a long-term survivor of hydranencephaly. Case presentation A 32-year-old man with severe cerebral palsy due to hydranencephaly was referred to our department for the evaluation of a subcutaneous lump in the lower right abdomen. He was a long-term survivor of hydranencephaly. After confirming the diagnosis of right testicular cancer originating in his undescended testes, surgical resection was performed. Pathological examination revealed a mixed-type germ cell tumor. Conclusion The decision-making process for treating malignant tumors, like testicular cancer, in adults with severe cerebral palsy can be challenging. Clinical ethics consultation could be helpful in avoiding treatment delays.

Diagnostic role of gray-scale and shear-wave elastography in pediatric patients with undescended testes: a prospective controlled study. J Ultrason 2024; 24:1-7. [PMID: 38343787 PMCID: PMC10850941 DOI: 10.15557/jou.2024.0004] [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: 06/25/2023] [Accepted: 09/11/2023] [Indexed: 04/26/2024] Open
Abstract
Aim Ultrasound elastography is a simple non-invasive method for measuring tissue elasticity in relation to tissue fibrosis. The aim of this study was to compare echogenicity, volume and shear wave velocities of undescended vs normally descended testes. Material and methods Sixty-six boys with undescended testes were included in this study. The median age range was 35.5 (10-118) months old. The cases included in this prospective study consisted of 66 patients with non-operated undescended testes, with 51 of them being affected unilaterally and 15 affected bilaterally, as diagnosed by physical examination. The control group consisted of 31 healthy boys without any particular health problems. This prospective study was performed by gray-scale ultrasonography and shear wave elastography in boys with undescended testes and healthy testes. The testicular volumes were established by ultrasound measurement, the echogenicity and shear wave elastography values were measured in boys with unilateral and bilateral undescended testes, and the results were compared with healthy boys' testes and their contralateral testes. The stiffness values were recorded for speed (m/s) and elasticity (kPa), and the stiffness values of undescended testes were compared with the healthy control group. Results Echogenicity values were lower in the bilateral undescended testes group than in the healthy group, and the healthy group's echogenicity was normal (p <0.001). The ROC curve was used to identify a cut-off shear wave elastography value for predicting decreased testicular echogenicity by using average shear wave elastography values. The area under the curve for the undescended testes was 0.78 (95% CI: 0.70-0.85, sensitivity 83.7%, specificity 68.7%, p <0.001), with an average shear wave elastography value of 2.32 (m/s) for above the cut-off point indicates. This was found to be significantly associated with reduced echogenicity on gray-scale ultrasonography, suggesting that it may be correlated with fibrosis developing in patients with undescended testes. Conclusion The study provides interesting findings in that it proposes an alternative non-invasive method for the assessment of testicular tissue in undescended testes. We used shear wave elastography to compare the stiffness of normal testes in both heathy patients and in the contralateral healthy testes of boys with undescended testes, with the values obtained for the undescended testes reflecting the level of fibrosis of the parenchyma. Another outcome of this study was observed in patients with unilateral undescended testes, where the normally descended testes showed increased shear wave elastography values, which could be an early indication of parenchymal change.

Techniques of staged laparoscopic orchidopexy for high intra-abdominal testes in children: A systematic review and meta-analysis. Urol Ann 2024; 16:64-70. [PMID: 38415237 PMCID: PMC10896330 DOI: 10.4103/ua.ua_11_23] [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: 01/17/2023] [Accepted: 08/21/2023] [Indexed: 02/29/2024] Open
Abstract
Background Laparoscopic exploration is currently considered the gold standard for managing nonpalpable intraabdominal testes. The problem of short vascular pedicle is addressed in Fowler-Stephen (FS) technique by the division of testicular vessels and in Shehata technique (ST) by traction on testicular vessels. There is a lack of the consensus among pediatric surgeons on the choice of one technique over other. This analysis compares the reported outcomes of staged laparoscopic orchidopexy by ST with the time tested FS technique in managing high intraabdominal undescended testis. Materials and Methods The present systematic review and meta-analysis was conducted as per the preferred reporting items for the systematic review and meta-analyses guidelines. Only randomized controlled trials and comparative studies were included. The primary outcomes compared were the incidence of testicular atrophy, testicular retraction/ascent rate, and operative time of Stage I and Stage II orchidopexy. Results The present analysis was based on three randomized studies with a total of 119 undescended testes in 117 patients satisfying the inclusion criteria. The operative time was less in Stage I FS technique; however, there was no statistically significant difference in operative time of both procedures during the Stage II laparoscopic orchidopexy. Pooled analysis of postintervention testicular atrophy, testicular retraction rate, and duration of postoperative hospitalization showed no difference between both procedures. Conclusion Both FS and STs are comparable in terms of postintervention testicular atrophy, testicular retraction/ascent; however, the mean operative time is significantly less with FS technique in Stage I laparoscopic orchidopexy.

Environmental oestrogens disrupt testicular descent and damage male reproductive health: Mechanistic insight. J Cell Mol Med 2023. [PMID: 37409668 PMCID: PMC10399541 DOI: 10.1111/jcmm.17837] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2023] [Revised: 06/18/2023] [Accepted: 06/27/2023] [Indexed: 07/07/2023] Open
Abstract
Environmental oestrogens (EEs) as environmental pollutants have been paid much attention due to their impact on congenital malformation of male genitourinary system. Exposure to EEs for prolonged time could hinder testicular descent and cause testicular dysgenesis syndrome. Therefore, it is urgent to understand the mechanisms by which EEs exposure disrupt testicular descent. In this review, we summarize recent advances in our understanding of the process of testicular descent, which is regulated by intricate cellular and molecular networks. Increasing numbers of the components of these networks such as CSL and INSL3 are being identified, highlighting that testicular descent is a highly orchestrated process that is essential to human reproduction and survival. The exposure to EEs would lead to the imbalanced regulation of the networks and cause testicular dysgenesis syndrome such as cryptorchidism, hypospadias, hypogonadism, poor semen quality and testicular cancer. Fortunately, the identification of the components of these networks provides us the opportunity to prevent and treat EEs induced male reproductive dysfunction. The pathways that play an important role in the regulation of testicular descent are promising targets for the treatment of testicular dysgenesis syndrome.

Elevated plasma miR-210 expression is associated with atypical genitalia in patients with 46,XY differences in sex development. Mol Genet Genomic Med 2022; 10:e2084. [PMID: 36369742 PMCID: PMC9747552 DOI: 10.1002/mgg3.2084] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2022] [Revised: 09/09/2022] [Accepted: 10/21/2022] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Differences of sex development (DSD) is a term used for conditions in which the chromosomal, gonadal or phenotypical sex is atypical. 46,XY DSD patients frequently present undervirilized external genitalia. The expression of different miRNAs in many organs of the male genital system has been reported, and these miRNAs have been associated with testicular function and its disorders, but no description has been related to DSD conditions. This study aimed to evaluate the plasma expression of miR-210 in 46,XY DSD patients who presented atypical genitalia at birth. METHODS Eighteen 46,XY DSD patients who presented atypical genitalia (undescended testis and/or hypospadias, bifid scrotum or micropenis) at birth and 36 male control individuals were selected. Plasma levels of miR-210 and reference miR-23a were measured using RT-qPCR and the data were analysed by the 2-ΔCt method. RESULTS MiR-210 plasma levels were significantly higher in 46,XY DSD patients with atypical genitalia than in male control subjects (p = 0.0024). A positive association between miR-210 levels and the presence of cryptorchidism and hypospadias (p = 0.0146 and p = 0.0223) was found in these patients. Significantly higher levels of miR-210 were observed in patients with 46,XY DSD and cryptorchidism than in control subjects (p = 0.0118). These results are in agreement with previous literature reports, in which increased levels of miR-210 expression were observed in human testicular tissue from adult males with undescended testes in comparison with samples of descended testes. CONCLUSION Our study showed a positive association between the presence of atypical genitalia and plasma levels of miR-210 expression in the group of patients with 46,XY DSD of unknown aetiology studied. These findings contribute to reveal a new perspective on the role of miRNAs in the development of male external genitalia and the broad spectrum of phenotypes presented by patients with 46,XY DSD.

A prospective observational study to evaluate the change in inhibin-B as a marker of sertoli cell function in children subjected to surgical correction for undescended testes. Afr J Paediatr Surg 2022; 19:233-237. [PMID: 36018204 PMCID: PMC9615955 DOI: 10.4103/ajps.ajps_96_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/06/2022] Open
Abstract
BACKGROUND AND OBJECTIVES Undescended testes (UDT) or cryptorchidism is a common congenital disability characterised by the absence of at least one testicle from the scrotum. The primary aim of surgical correction is to preserve fertility potential and prevent complications including trauma, malignancy, hernia and torsion. Often, children, especially in developing countries, present late with UDT. The effect of surgical correction in the recovery of Sertoli cell function in children aged more than 2 years is not apparent. The present study was conducted to study the change in inhibin-B level as a marker of Sertoli cell function in surgically corrected UDT in a heterogeneous population. MATERIALS AND METHODS A prospective observational study conducted over a 3-year period at a tertiary care paediatric surgery centre recruited 76 children with UDT undergoing surgical correction. Inhibin-B as a marker for Sertoli cell function was studied preoperatively and postoperatively. Continuous variables were summarised by calculating mean, standard deviation, median and interquartile range (IQR). Quantile versus quantile plotting was done to assess the distribution of the data. Data were analysed in two groups, with participants aged <2 years (Group A) and more than 2 years (Group B). Wilcoxon signed-rank test was used to compare the pre-operative and post-operative value. RESULTS In Group A (n = 39), the median (IQR) of pre-operative inhibin-B was 181 pg/ml (148-254) and post-operative inhibin-B was 230 pg/ml (176-296). In Group B, the median (IQR) of pre-operative inhibin was 70 pg/ml (44-104) and post-operative inhibin was 102 pg/ml (46-176). There was a significant increase in post-operative inhibin when compared to the pre-operative inhibin (P = 0.015 and 0.012, respectively, in Group A and B). Luteinizing hormone (LH) showed a significant decrease (P = 0.002) in Group A following surgery but bordering on significance in Group B (P = 0.43). On the other hand, follicle-stimulating hormone showed a significant decrease (P < 0.01) in Group B following surgery but not in Group A (P = 0.87). CONCLUSION The mean post-operative inhibin-B levels were increased significantly as compared to the pre-operative levels indicating either a successful orchiopexy/adequate germ cell number or both. The benefit of orchiopexy may extend even to children presenting late for evaluation.

Continued use of scrotal ultrasounds for the workup of undescended testes: Confirmation bias and inaccuracies. J Paediatr Child Health 2022; 58:1384-1389. [PMID: 35478367 DOI: 10.1111/jpc.15998] [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: 03/01/2022] [Revised: 03/22/2022] [Accepted: 04/11/2022] [Indexed: 11/27/2022]
Abstract
AIM Scrotal ultrasounds are utilised in some primary care settings for suspected cryptorchidism, despite inaccuracies. We aim to identify the correlation between ultrasound and primary care provider (PCP) findings of undescended testicles (UDTs) as a potential source of confirmation bias. METHODS Males referred for suspected UDT by PCPs who underwent scrotal ultrasound and paediatric urologist examination from 2014 to 2019 were included. Correlation between PCP and ultrasound findings and diagnostic accuracy were evaluated. Logistic regression was utilised to determine associations between patient factors and UDT misdiagnosis. RESULTS Out of 145 testes, ultrasound corroborated PCPs' UDT diagnoses 87.6% of the time, 49.6% of which were confirmed as UDT by paediatric urologists. Ultrasound had a false positivity rate of 81.0% and specificity of 19.0%. Ultrasound versus paediatric urologist findings regarding testicle location were significantly different (P < 0.0001). Patients aged ≥8 years old had 5.2 times greater odds of being misdiagnosed with UDT than patients <8 years old (95% confidence interval: 1.6-16.7; P < 0.002) by PCP and ultrasound. CONCLUSION Scrotal ultrasound highly corroborated PCPs' UDT diagnoses. Older patients were more likely to be misdiagnosed with UDT by PCP and ultrasound. As ultrasounds rarely refute PCP examinations for suspected UDTs and are highly inaccurate, confirmation bias may explain the use of ultrasound in the workup of UDT.

Comparison of Single-Incision Scrotal Orchiopexy and Traditional Two-Incision Inguinal Orchiopexy for Primary Palpable Undescended Testis in Children: A Systematic Review and Meta-Analysis. Front Pediatr 2022; 10:805579. [PMID: 35372152 PMCID: PMC8964791 DOI: 10.3389/fped.2022.805579] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2021] [Accepted: 01/19/2022] [Indexed: 02/01/2023] Open
Abstract
PURPOSE To compare the safety, efficacy, and cosmetic results of single-incision scrotal orchiopexy (SISO) and traditional two-incision inguinal orchiopexy (TTIO) for primary palpable undescended testes (PUDTs) in children. MATERIALS AND METHODS A systematic literature search of all relevant studies published on PubMed, Embase, Medline, Cochrane Library, Web of Science database, and Wanfang data until July 2021 was conducted. The operative time, hospitalization duration, conversion rate, wound infection or dehiscence, scrotal hematoma or swelling, testicular atrophy, reascent, hernia or hydrocele, analgesics needs, and cosmetic results were compared between SISO and TTIO using the Mantel-Haenszel or inverse-variance method. RESULTS A total of 17 studies involving 2,627 children (1,362 SISOs and 1,265 TTIOs) were included in the final analysis. The conversion rate of SISO was 3.6%. The SISO approach had a statistically significant shorter operative time than the TTIO approach for PUDT (weighted mean difference-11.96, 95% confidence interval -14.33 to -9.59, I2 = 79%, P < 0.00001) and a shorter hospital stay (weighted mean difference-1.05, 95% confidence interval -2.07 to -0.03, P = 0.04). SISO needed fewer analgesics and had better cosmetic results than TTIO. SISO had a similar total, short-term, or long-term complication rate with TTIO. CONCLUSION Compared with TTIO, SISO has the advantages of shorter operative time, shorter hospitalization duration, less postoperative pain, and better cosmetic appealing results. SISO is a safe, effective, promising, and potential minimal invasive surgical approach for PUDT. SISO is an alternative to TTIO in selected cryptorchid patients, especially for lower positioned ones.

Association of antimullerian hormone with the size of the appendix testis, the androgen and estrogen receptors and their expression in the appendix testis, in congenital cryptorchidism. J Pediatr Endocrinol Metab 2021; 34:1247-1255. [PMID: 34265880 DOI: 10.1515/jpem-2021-0240] [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: 04/03/2021] [Accepted: 06/20/2021] [Indexed: 11/15/2022]
Abstract
OBJECTIVES Antimullerian hormone (AMH) causes regression of the mullerian ducts in the male fetus. The appendix testis (AT) is a vestigial remnant of mullerian duct origin, containing both androgen (AR) and estrogen (ER) receptors. The role of both AMH and AT in testicular descent is yet to be studied. We investigated the possible association of AMH with AT size, the AR and ER, and their expression in the AT, in congenital cryptorchidism. METHODS A total of 26 patients with congenital unilateral cryptorchidism and 26 controls with orthotopic testes were investigated, and 21 ATs were identified in each group. AMH and insulin-like three hormone (INSL3) concentrations were measured with spectrophotometry. AR and ER receptor expression was assessed with immunohistochemistry using monoclonal antibodies R441 for AR and MAB463 for ER. For the estimation of receptor expression, the Allred Score method was used. RESULTS AMH concentrations did not present significant differences between patients with congenital cryptorchidism and the controls. Also, no correlation was found between AMH, INSL3, and AT length. Allred scores did not present significant differences. However, expression percentiles and intensity for both receptors presented significant differences. Three children with cryptorchidism and the highest AMH levels also had the highest estrogen receptor scores in the AT. CONCLUSIONS No association was found between AMH and the studied major parameters. However, higher AMH concentrations, in combination with higher estrogen receptor scores in the AT, may play a role in cryptorchidism in some children. Larger population samples are needed to verify this observation.

Utility of Laparoscopic Approach of Orchiopexy for Palpable Cryptorchidism: A Systematic Review and Meta-Analysis. CHILDREN-BASEL 2021; 8:children8080677. [PMID: 34438568 PMCID: PMC8392196 DOI: 10.3390/children8080677] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/11/2021] [Revised: 08/01/2021] [Accepted: 08/02/2021] [Indexed: 11/26/2022]
Abstract
Background: Traditional open orchiopexy is still a standard of treatment for palpable undescended testicles. Recently several authors reported successful results using a laparoscopic approach in the treatment of palpable cryptorchidism. The present systematic review and meta-analysis investigated the utility of laparoscopic orchiopexy for palpable cryptorchidism. Methods: Scientific databases (PubMed, Scopus, Web of Science, and EMBASE) were systematically searched for relevant articles using the following terms: (palpable cryptorchidism or palpable undescended testes) AND (laparoscopic orchiopexy or laparoscopic orchiopexy). The inclusion criteria were all children with unilateral or bilateral palpable undescended testes who underwent laparoscopic orchiopexy (LO) compared to children who underwent conventional open orchiopexy (CO). The main outcomes were the proportion of children requiring redo-orchiopexy and the incidence of postoperative complications. Secondary outcomes were duration and the cost of surgery. Results: The final meta-analysis included five studies involving 705 children; LO, n = 369 (52.3%) and CO, n = 336 (47.7%). The majority of the included patients had unilateral palpable cryptorchidism. No significant differences were found in regard to average age at the time of surgery and follow-up periods between the investigated groups. No statistically significant differences were found in regard to redo-orchiopexy rates (RR = 0.22, 95% CI 0.03–1.88, p = 0.17), early complications (RR = 0.66, 95% CI 0.21–2.08, p = 0.48) and incidence of testicular atrophy (RR = 0.36, 95% CI 0.03–3.88, p = 0.40). No significant differences in the operative duration were observed among the groups. Laparoscopy was associated with higher costs in most of the studies. Conclusion: LO is safe and effective in children with palpable cryptorchidism. The rates of redo-orchiopexy as well as an incidence of early complications and testicular atrophy rates are comparable to CO.

Abstract
Background: Laparoscopic orchiopexy (LO) has become a standard procedure for the treatment of nonpalpable undescended testes (UDT). LO for palpable UDT is still controversial. The aim of this study is to explore the method and effect of LO procedure for palpable UDT in children suffering from cryptorchidism. Methods: A retrospective study was performed for LO and traditional inguinal incision orchiopexy (TIO) for palpable UDT. A total of 291 children were enrolled, and they were aged 9-96 months with either left- or right-side palpable inguinal canalicular testes. Patients with testes that were nonpalpable, ectopic, and retractable were excluded. One hundred seventy patients received LO and 121 patients received TIO. Patient age, operative time, and clinical outcomes were reviewed. Independent t-test and Fisher's exact test were performed by SPSS 25.0 software. Results: The mean operative time (30.77 ± 6.02 minutes versus 44.76 ± 6.70 minutes) and postoperative normal activity time (1.25 ± 0.43 days versus 2.48 ± 0.68 days) of LO were significantly shorter than those of TIO group (P < .05). Forty-seven of 49 cases (95.9%) aged <1 year successfully achieved LO. Conclusion: LO is an appropriate choice for palpable UDT, especially in younger children aged <2 years. The success rate of LO decreased with age.

Abstract
Pubic bone aplasia is a rare finding that is either diagnosed as incidental finding or associated with various clinical syndromes. It is usually discovered in early childhood, however, there are few reported cases of late discovery during adulthood. We present a case of a 64-year-old male with unilateral superior pubic rami aplasia, discovered incidentally during workup for sustained trauma. Our patient reported treatment for unilateral hip dislocation in his early childhood and had a history of operated undescended testes ipsilaterally. This exact constellation of pubic rami aplasia, undescended testes and hip dysplasia is unique in the available literature. Even though our patient had a normal life and the pubic aplasia was discovered incidentally, it is important to always assess these patients for systemic involvement, either from the musculoskeletal system or other organs, in order to provide better treatment for them.

Abstract
Transverse testicular ectopia (TTE) is an uncommon anatomical abnormality where both the gonads migrate toward the same hemiscrotum. Embryologically, several theories regarding the origin of TTE have been suggested including adhesion and fusion of developing Wolffian canals, aberrant gubernaculum, testicular adhesions, defective formation of the internal inguinal ring, and traction on the testis by persistent Mullerian structures. To date, about 100 cases of TTE have been reported in the literature. Herein, we report five cases of TTE operated in the Department of Paediatric Surgery, Sardar Patel Medical College, Bikaner, over a period of 5 years. All cases were in the age group of 3 months to 4 years, out of which four were diagnosed preoperatively by clinical examination and ultrasonography (USG). Two of these four cases presented with inguinoscrotal swellings and contralateral undescended testes and other two presented with absence of testes in the scrotum. One case presented with a scrotal abscess which revealed both the testes in the abscess cavity. All five cases were operated upon with herniotomy and transseptal orchidopexy and discharged successfully. TTE, although rare, has a spectrum of presentations and should be kept in mind as a possibility in cases of inguinoscrotal disorders in young age group. A preoperative USG may be helpful in conformation of diagnosis.

Abstract
Background The appendix testis (AT) is the most common vestigial remnant of the human testis. Variations in the presence and expression of AT androgen receptor (AR) and estrogen receptor (ER) have been reported in cryptorchidism. We studied the possible association of AR and ER expression of the AT with cryptorchidism. Methods ATs were resected from 40 boys who underwent inguinoscrotal surgery, (20 patients with congenital unilateral cryptorchidism [UC] and 20 controls with orthotopic testes and hydrocele). AR and ER expression was evaluated with immunohistochemistry, and the percentage and intensity of AR and ER expression were evaluated by the Allred scoring method. AT length was compared between the two groups. Correlation of AR and ER expression was evaluated independently in patients and controls. Results The Allred score for AR trended toward lower values in UC compared to controls (p = 0.193), while ER scores presented statistically significant lower values in UC compared to controls (p = 0.017). No significant difference or trend was found in the expression of both receptors between high and low cryptorchidism (p = 0.981 for AR, p = 0.824 for ER) and for the appendiceal length between UC and controls (p = 0.369). Conclusions The findings of a trend for lower AR expression and a statistically significant lower expression of ER in UC may suggest an association of AR and ER with cryptorchidism and may provide an insight into the process of testicular descent.

Congenital lipoid adrenal hyperplasia: Immunohistochemical study of testosterone synthesis in Leydig cells. IJU Case Rep 2020; 3:53-56. [PMID: 32743469 PMCID: PMC7292164 DOI: 10.1002/iju5.12142] [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: 10/30/2019] [Accepted: 12/16/2019] [Indexed: 11/30/2022] Open
Abstract
INTRODUCTION Congenital lipoid adrenal hyperplasia is a rare disease that causes disorders of sex development. The 46,XY patient presents with female external genitalia and inguinal testes. We describe the case of a patient with congenital lipoid adrenal hyperplasia and investigated the testes of this patient in detail. CASE PRESENTATION A 15-day-old 46,XY neonate presented with severe adrenal insufficiency. Congenital lipoid adrenal hyperplasia was diagnosed after detection of steroidogenic acute regulatory gene mutations. At 2 years and 5 months, she underwent bilateral gonadectomy. Leydig cells were observed both with and without lipid droplets in the testes of this patient. We also demonstrated immunohistochemically that some testosterone-synthesizing enzymes were maintained in this patient. CONCLUSION The results indicated transcription of testosterone-synthesizing enzymes remained despite lipid accumulation in this patient. The pattern of expression of testosterone-synthesizing enzymes suggested fetal Leydig cells may have remained after birth in the testes of this patient.

Scrotal Ultrasound Is Not Routinely Indicated in the Management of Cryptorchidism, Retractile Testes, and Hydrocele in Children. Glob Pediatr Health 2019; 6:2333794X19890772. [PMID: 31803796 PMCID: PMC6876163 DOI: 10.1177/2333794x19890772] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2019] [Revised: 10/22/2019] [Accepted: 10/24/2019] [Indexed: 11/29/2022] Open
Abstract
Cryptorchidism, or undescended testes, is the most common congenital genitourinary anomaly. A failure or delay of treatment may result in reduced fertility or an increased risk of testicular cancer. The American Urological Association (AUA) recommends that a scrotal ultrasound (SUS) not be performed in the preoperative management of cryptorchidism. This study investigated how likely pediatricians were to perform SUS despite the AUA guidelines. We retrospectively studied 243 patients referred to a single pediatric urology practice for clinically diagnosed testis pathology including undescended testis, hydrocele, and retractile testis over a 4-year period (January 1, 2015, to December 30, 2018). A total of 72 patients (29.6%) underwent a SUS ordered by their pediatrician prior to the pediatric urology visit. Pediatricians should be aware that SUS performed prior to pediatric urological evaluation does not alter management and is associated with a significant financial cost in patients with cryptorchidism or hydrocele.

Novel combined insulin-like 3 variations of a single nucleotide in cryptorchidism. J Pediatr Endocrinol Metab 2019; 32:987-994. [PMID: 31444964 DOI: 10.1515/jpem-2018-0547] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/11/2018] [Accepted: 06/17/2019] [Indexed: 11/15/2022]
Abstract
Background Insulin-like 3 hormone (INSL3) is involved in the process of testicular descent, and has been thoroughly studied in cryptorchidism. However, INSL3 allelic variations found in the human genome were heterozygous and only a few of them were found exclusively in patients with cryptorchidism. Under this perspective, we aimed to study the presence of INSL3 allelic variations in a cohort of patients with cryptorchidism and to estimate their potential consequences. Methods Blood samples were collected from 46 male patients with non-syndromic cryptorchidism and from 43 age-matched controls. DNA extraction and polymerase chain reaction (PCR) were performed for exons 1 and 2 of the INSL3 gene in all subjects. Sequencing analysis was carried out on the PCR products. All data were grouped according to testicular location. Results Seven variations of a single nucleotide (SNVs) were identified both in patients with cryptorchidism and in controls: rs2286663 (c.27G > A), rs1047233 (c.126A > G) and rs6523 (c.178A > G) at exon 1, rs74531687 (c.191-30C > T) at the intron, rs121912556 (c.305G > A) at exon 2 and rs17750642 (c.*101C > A) and rs1003887 (c.*263G > A) at the untranslated region (UTR). The allelic variants rs74531687 and rs121912556 were found for the first time in the Greek population. The novel homozygotic combination of the three allelic variants rs1047233-rs6523-rs1003887 seemed to present a stronger correlation with more severe forms of cryptorchidism. Conclusions The combination of specific INSL3 SNVs rather than the existence of each one of them alone may offer a new insight into the involvement of allelic variants in phenotypic variability and severity.

Abstract
Background: Cryptorchidism is one of the most frequent congenital birth defects in male children and is present in 2-4% of full-term male births. It has several possible health effects including reduced fertility, increased risk for testicular neoplasia, testicular torsion, and psychological consequences. Cryptorchidism is often diagnosed as comorbid; copresent with other diseases. It is also present in clinical picture of several syndromes. However, this field has not been systematically studied. The aim of the present study was to catalog published cases of syndromes which include cryptorchidism in the clinical picture and associated genomic information. Methods: The literature was extracted from Public/Publisher MEDLINE and Web of Science databases, using the keywords including: syndrome, cryptorchidism, undescended testes, loci, and gene. The obtained data was organized in a table according to the previously proposed standardized data format. The results of the study were visually represented using Gephi and karyotype view. Results: Fifty publications had sufficient data for analysis. Literature analysis resulted in 60 genomic loci, associated with 44 syndromes that have cryptorchidism in clinical picture. Genomic loci included 38 protein-coding genes and 22 structural variations containing microdeletions and microduplications. Loci, associated with syndromic cryptorchidism are located on 16 chromosomes. Visualization of retrieved data is presented in a gene-disease network. Conclusions: The study is ongoing and further studies will be needed to develop a complete catalog with the data from upcoming publications. Additional studies will also be needed for revealing of molecular mechanisms associated with syndromic cryptorchidism and revealing complete diseasome network.

Anti-Müllerian Hormone and Testicular Function in Prepubertal Boys With Cryptorchidism. Front Endocrinol (Lausanne) 2018; 9:182. [PMID: 29922225 PMCID: PMC5996917 DOI: 10.3389/fendo.2018.00182] [Citation(s) in RCA: 36] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2018] [Accepted: 04/04/2018] [Indexed: 12/14/2022] Open
Abstract
INTRODUCTION The functional capacity of the testes in prepubertal boys with cryptorchidism before treatment has received very little attention. The assessment of testicular function at diagnosis could be helpful in the understanding of the pathophysiology of cryptorchidism and in the evaluation of the effect of treatment. Anti-Müllerian hormone is a well-accepted Sertoli cell biomarker to evaluate testicular function during childhood without the need for stimulation tests. OBJECTIVE The aim of the study was to assess testicular function in prepubertal children with cryptorchidism before orchiopexy, by determining serum anti-Müllerian hormone (AMH). We also evaluated serum gonadotropins and testosterone and looked for associations between testicular function and the clinical characteristics of cryptorchidism. MATERIALS AND METHODS We performed a retrospective, cross-sectional, analytical study at a tertiary pediatric public hospital. All clinical charts of patients admitted at the outpatient clinic, and recorded in our database with the diagnosis of cryptorchidism, were eligible. The main outcome measure of the study was the serum concentration of AMH. Secondary outcome measures were serum LH, FSH, and testosterone. For comparison, serum hormone levels from a normal population of 179 apparently normal prepubertal boys were used. RESULTS Out of 1,557 patients eligible in our database, 186 with bilateral and 124 with unilateral cryptorchidism were selected using a randomization software. Median AMH standard deviation score was below 0 in both the bilaterally and the unilaterally cryptorchid groups, indicating that testicular function was overall decreased in patients with cryptorchidism. Serum AMH was significantly lower in boys with bilateral cryptorchidism as compared with controls and unilaterally cryptorchid patients between 6 months and 1.9 years and between 2 and 8.9 years of age. Serum AMH below the normal range reflected testicular dysfunction in 9.5-36.5% of patients according to the age group in bilaterally cryptorchid boys and 6.3-16.7% in unilaterally cryptorchid boys. FSH was elevated in 8.1% and LH in 9.1% of boys with bilateral cryptorchidism, most of whom were anorchid. In patients with present testes, gonadotropins were only mildly elevated in less than 5% of the cases. Basal testosterone was mildly decreased in patients younger than 6 months old, and uninformative during childhood. CONCLUSION Prepubertal boys with cryptorchidism, especially those with bilaterally undescended gonads, have decreased AMH production. Although serum AMH may fall within the normal range, there is a considerable prevalence of testicular dysfunction during childhood in this frequent condition.

Abstract
Introduction Undescended testes are recognised in 1% to 2% of boys during the first year of life, and about 20% of them are impalpable. Ultrasonography (US) may establish the localisation of the testis but the final diagnosis is usually determined laparoscopically. Aim To evaluate long-term results of laparoscopic treatment of boys with impalpable testes and sensitivity of preoperative ultrasound. Material and methods Between 2011 and 2015, we operated on 545 boys with undescended testes. Sixty-two of them with 65 impalpable testes were treated laparoscopically – the study group. Mean age was 3.5 years. The study group was divided into 5 groups according to type of treatment. The volume and position of the operated gonad were assessed manually and by ultrasound. Results In group 1 testicular agenesis was observed in 19 patients. In group 2 revision of the inguinal canal revealed testicular agenesis in 7 and atrophy in 4 patients. In group 3 conversion to classic orchiopexy was performed in 10 patients. In group 4 one-stage orchiopexy was performed in 9 patients on 12 testes. In group 5 a two-stage F-S procedure was performed in 13 patients. Ten testes in group 4 had a volume in the normal range (84%) and also 10 testes in group 5 (77%). Conclusions Laparoscopy in impalpable testes is the procedure of choice and allows definitive management, even when conversion to open procedure is necessary. Sensitivity of preoperative ultrasound is generally about 60% for true intra-abdominal testes, so diagnostic laparoscopy is necessary.

Abstract
The aim of this study was to evaluate the testicular volume and structure using ultrasound (US) before and up to 3 years after orchidopexy in children with different age.A total of 128 patients underwent orchidopexy for undescended testes. Afterwards, patients were invited for annual follow-up and control scrotal US. The total number of analyzed testes after orchidopexy was 184. Patients were divided according to age at the time of surgery: group I (2-4 years old), group II (5-7), and group III (8-10). In all patients, the testicular volume ratio was calculated as the operated testes volume versus the control testes mean volume.There was an increase in the median ratio in all age groups, from 0.86 to 0.95 in group I, 0.82 to 0.92 in group II and 0.78 to 0.90 in group III. In group of the patients 2 to 4 years old the growth of the ratio 3 years after surgery was statistically significant.Abnormalities in the structure of the testes, which may indicate severe damage to the testis, were seen in approximately 20% of patients on initial exams. On follow-up exams, this type of structure remained in 7% of patients. Testes with an initial ratio <0.25 and inhomogeneous structure did not show any significant growth.Scrotal US can be used for an accurate comparative assessment of the structure and growth of the testes before and after orchidopexy.Abnormalities in the structure of the testes may identify testes requiring more advanced methods of evaluation.

Abstract
Polyorchidism is defined as the presence of more than two testes. This rare congenital anomaly has been reported with only 140 pathologically proven cases in the published literature to date. While triorchidism is the most common variation and generally affects the left side, bilateral polyorchidism is even rare and only seven cases of patients with four testes have been reported in the literature. There is no consensus in the literature regarding the management of supernumerary testis due to its rareness. We report such a rare case of a 20-year-old male patient, who was presented with left-sided scrotal mass and right inguinal swelling and, diagnosed as polyorchidism including four distinct testes, with two of them in left hemiscrotum and the other two testes in the right inguinal canal. The patient underwent orchiopexy for the normal looking right-sided testis, and orchiectomy for the right-sided supernumerary testis being dysmorphic and potential malignancy risk. Histopathological examination confirmed the excised tissue to be severely atrophic testicle. The patient is still following with regular self-examination and scrotal ultrasonography. Polyorchidism should be keep in mind especially for the differential diagnosis of extratesticular and paratesticular masses. Physical examination may not be sufficient, and radiologic examination can provide accurate diagnosis. Conservative, extirpative or reconstructive approaches could be performed based on individual basis by reproductive potential and location of supernumerary testis, coexistence of other disorders and suspicion of malignancy.

Abstract
The best mode of undescended testis (UDT) treatment remains controversial. However, knowledge gained from randomized controlled studies and meta-analyses allowed different groups of researchers to set out guidelines on management of patients with UDT. The authors reviewed recent literature and came to the following conclusions: (1) Hormonal treatment is not recommended, considering both the immediate results (only 15-20% of retained testes descend) and the possible long-term adverse effects on spermatogenesis. (2) Surgery is the treatment of choice; orchiopexy is successful in about 95% of UDT, with a low rate of complications (about 1%). (3) Orchiopexy should be performed between 12 and 18 months of age, or at first contact if diagnosed later.

Abstract
Background: Ambiguous genitalia is a hereditary disorder that usually requires early attention and detection. The discovery of ambiguous genitalia in a neonate is situation that could be difficult to manage, not only because of complications such as salt-losing, but also due to the importance of sex determination before psychological gender could be established. Awareness of the prevalence of ambiguous genitalia can affect the attitude and consideration of physicians and related medical personnel about disease in different communities. So in this study, the prevalence of ambiguous genitalia and undescended testes (UDT) in Iran was reported. Materials and Methods: This national study was conducted in 2009-2010 as part of the routine screening examinations at school entry in Iran. The physical examinations were performed for students at entry to three school levels by physicians and medical personnel. Execution and conduction of this program was the duty of the University of Medical Sciences in each province. Results: On average, the prevalence of ambiguous genitalia was 0.04% at national level (0.03%, 0.05%, and 0.03% at 6, 12, and 15 year olds, respectively). The prevalence of ambiguous genitalia was not significantly different according to age group and living area. The average of UDT) prevalence in the whole country was 0.13%. The prevalence of UDT was higher at elementary school level than in the other two levels. Conclusion: Although the prevalence of genitalia abnormalities was not high in the school students in Iran, given the importance of the issue and in order to find the ambiguous genitalia or UDT, medical examinations and parental notification should be taken seriously at an earlier age.

Abstract
Cryptorchidism represents the most common endocrine disease in boys, with infertility more frequently observed in bilateral forms. It is also known that undescended testes, if untreated, lead to an increased risk of testicular tumors, usually seminomas, arising from mutant germ cells. In normal testes, germ cell development is an active process starting in the first months of life when the neonatal gonocytes transform into adult dark (AD) spermatogonia. These cells are now thought to be the stem cells useful to support spermatogenesis. Several researches suggest that AD spermatogonia form between 3 and 9 months of age. Not all the neonatal gonocytes transform into AD spermatogonia; indeed, the residual gonocytes undergo involution by apoptosis. In the undescended testes, these transformations are inhibited leading to a deficient pool of stem cells for post pubertal spermatogenesis. Early surgical intervention in infancy may allow the normal development of stem cells for spermatogenesis. Moreover, it is very interesting to note that intra-tubular carcinoma in situ in the second and third decades have enzymatic markers similar to neonatal gonocytes suggesting that these cells fail transformation into AD spermatogonia and likely generate testicular cancer (TC) in cryptorchid men. Orchidopexy between 6 and 12 months of age is recommended to maximize the future fertility potential and decrease the TC risk in adulthood.

Abstract
Due to its noninvasiveness and high resolving power, ultrasound examination is the examination of choice for the imaging of the structures of the pediatric scrotum. It allows to reveal changes impossible to find in the course of a clinical examination. Its significance has increased over the past few years due to the technological developments. The introduction of transducers with frequency of 10–17 MHz has improved the resolution of pediatric testes images as well as the resolution of the inguinal canals images, which has been of particular importance for the evaluation of undescended, retractile and abdominal testes. New diagnostic tools have also been introduced, such as 3D imaging or elastography, whose application has helped provide valuable additional information for the evaluation of pediatric testes, for treatment monitoring, and for post-surgical follow-up examinations. 3D imaging facilitates a more accurate evaluation of the location of an undescended testicle, testicular volume, and vascularization. Elastography may be used for the evaluation of focal lesions, post-ischemic lesions, unclear fluid spaces, undescended testes, and following orchiopexy.

Abstract
OBJECTIVE To review the primary orchidopexy failure rate and outcome of repeat orchidopexy in a tertiary paediatric surgical centre and identify risk factors. METHODS A prospectively collected and validated audits system was used to identify all boys having a repeat orchidopexy from August 1990 to December 2008 (18 years). RESULTS In total, 1538 boys underwent orchidopexy with 1886 testicles operated on. Of these 348 (22.6%) patients had bilateral cryptorchidism. A need for repeat orchidopexy was identified in 31 boys resulting in a primary failure rate of 1.6% over the 18 years. Unilateral orchidopexy as the primary operation had a 1.5% failure rate. The failure rate for bilateral cryptorchidism was 1.87% per testicle rising to 1.93% per testicle when the primary operation was synchronous bilateral orchidopexy. Orchidopexy failure occurred in 9 patients (1.97%) who were under 24 months, 15 (2.67%) who were between 24 and 72 months and 7 (0.8%) over 72 months at time of first operation. CONCLUSION Possible risk factors for primary orchidopexy failure are bilateral operation and older age at time of operation. Failure in achieving a satisfactory scrotal position (and testicular loss) following orchidopexy has been postulated as a potential surgical standard for revalidation of paediatric surgeons. This study adds important contemporary data to inform that process.

Abstract
Genetic, hormonal, and anatomical factors are believed to be involved in the etiology of undescended testes. Due to increased risk of infertility, testicular cancer, torsion and/or accompanying inguinal hernia (>90%) as well as cosmetic concerns, all these patients require treatment. In this review paper, we aimed to evaluate the success rates of treatment modalities used in undescended testes, beginning from 1930 to the present, and to draw attention to the possible risks and benefits and also the efficacy of hormonal therapy in the management of the disorder, which is still a controversial issue. Hormonal therapy may lead to penile growth, painful erection, and behavioral changes while on treatment. In recent years, it has been reported that human chorionic gonadotropin (hCG) treatment was associated with interstitial edema due to increased vascular permeability, inflammation-like changes, and several adverse effects on germ cells by increasing pressure and apoptotic process. It has also been reported that LHRH analogues have positive effects on germ cells by increasing fertility in patients undergoing unilateral or bilateral orchiopexy. In some studies, the success rate of hCG treatment was reported to be higher following buserelin. In some other studies, hCG treatment was recommended before orchiopexy to reduce the risk for surgical ischemia. There are a limited number of randomized controlled studies, so evidence showing the efficacy of hormonal therapy is insufficient. According to the 2007 Consensus Report of Nordic countries, it is recommended that surgery is the first-line treatment modality in undescended testes and that it should be performed by pediatric surgeons and urologists at the age of 6-12 months.

Abstract
Aims: Scrotal fixation (SF) is a known technique for the management of low undescended testes (UDT). SF assumes that most low UDT have no patent processus vaginalis (PPV) and can be managed via scrotal mobilization alone. We report our experience of the role of SF in the management of low UDT. Materials and Methods: A retrospective review of all palpable UDT operated on by the senior author between 1998 and 2008 was undertaken. Children diagnosed with palpable UDT were examined under general anesthesia; if the whole testis could be manipulated into the upper part of the scrotum, low UDT was assumed and SF was performed. Attempts to identify a PPV intraoperatively were made in all and, if found, the procedure was converted to standard inguinal incision orchidopexy. Results: One hundred and thirteen children with 134 UDT were identified. SF was performed in 55 testes; inguinal orchidopexy (IO) in 75 and four testes were excised. The median (IQR) age at SF was 5.5 [4.7–6.3] years. Three SF were converted to an IO when a PPV was discovered. The complications in SF were scrotal hematoma (n = 1) and superficial wound infection (n = 1). No post-operative herniae or atrophied testis were seen and none required a redo operation. The mean (SD) operative times for SF and IO were 29.5 (18.1) and 42.7 (16.6) min, respectively (P = 0.04). Conclusion: In our study, 52 of 55 (94.5%) patients with low UDT lacked a hernial sac and were successfully fixed by SF. SF is a viable, simple, quick and safe alternative to IO in the management of low UDT.

Abstract
CONTEXT Ultrasound is frequently obtained during the presurgical evaluation of boys with nonpalpable undescended testes, but its clinical utility is uncertain. OBJECTIVE To determine the diagnostic performance of ultrasound in localizing nonpalpable testes in pediatric patients. METHODS English-language articles were identified by searching Medline, Embase, and the Cochrane Library. We included studies of subjects younger than 18 years who had preoperative ultrasound evaluation for nonpalpable testes and whose testis position was determined by surgery. Data on testis location determined by ultrasound and surgery were extracted by 2 independent reviewers, from which ultrasound performance characteristics (true-positives, false-positives, false-negatives, and true-negatives) were derived. Meta-analysis of 12 studies (591 testes) was performed by using a random-effects regression model; composite estimates of sensitivity, specificity, and likelihood ratios were calculated. RESULTS Ultrasound has a sensitivity of 45% (95% confidence interval [CI]: 29-61) and a specificity of 78% (95% CI: 43-94). The positive and negative likelihood ratios are 1.48 (95% CI: 0.54-4.03) and 0.79 (95% CI: 0.46-1.35), respectively. A positive ultrasound result increases and negative ultrasound result decreases the probability that a nonpalpable testis is located within the abdomen from 55% to 64% and 49%, respectively. Significant heterogeneity limited the precision of these estimates, which was attributable to variability in the reporting of selection criteria, ultrasound methodology, and differences in the proportion of intraabdominal testes. CONCLUSIONS Ultrasound does not reliably localize nonpalpable testes and does not rule out an intraabdominal testis. Eliminating the use of ultrasound will not change management of nonpalpable cryptorchidism but will decrease health care expenditures.
