Scrotal incision orchiopexy for undescended testes with or without a patent processus vaginalis

Orchidopexy for undescended testis-rate and predictors of re-ascent

PURPOSE

This study aimed to investigate the rate of re-ascent requiring re-operation after primary orchidopexy and to investigate eventual differences between the inguinal and scrotal approach as well as other potential predictors for re-ascent.

METHODS

A retrospective cohort study of children treated for undescended testis (UDT) with orchidopexy between 2018 and 2022 was conducted. The primary outcome was re-ascent requiring re-operation, and the secondary outcome was atrophy rate. Independent variables were age, underlying conditions, side, surgical approach, operation time, bilaterality, congenital/ascended UDT, presence of scrotal hypoplasia, presence of a patent processus vaginalis, division of external oblique, and suture of the testis. Univariate and logistic regression were used to evaluate differences between groups and risk for re-ascent.

RESULTS

A total of 662 testes in 554 patients were included. Re-operation occurred in 6% (7% with inguinal approach, 3% with scrotal approach, p = 0.04). Re-operation was associated with younger age, congenital UDT, and inguinal approach, but neither of these variables remained significant in multivariate analyses. Atrophy occurred in one testis.

CONCLUSION

The rate of re-ascent was 6% and the atrophy rate was 0.15%. A larger study may find predictors for re-ascent but with very low absolute risk. The lower rate of re-ascent with the scrotal approach is probably due to selection bias.

Comparison of scrotal and inguinal orchiopexy for palpable undescended testis: a meta-analysis of randomized controlled trials

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.

Management of the undescended testis in children: An American Pediatric Surgical Association Outcomes and Evidence Based Practice Committee Systematic Review

PURPOSE

Management of undescended testes (UDT) has evolved over the last decade. While urologic societies in the United States and Europe have established some guidelines for care, management by North American pediatric surgeons remains variable. The aim of this systematic review is to evaluate the published evidence regarding the treatment of (UDT) in children.

METHODS

A comprehensive search strategy and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were utilized to identify, review, and report salient articles. Five principal questions were asked regarding imaging standards, medical treatment, surgical technique, timing of operation, and outcomes. A literature search was performed from 2005 to 2020.

RESULTS

A total of 825 articles were identified in the initial search, and 260 were included in the final review.

CONCLUSIONS

Pre-operative imaging and hormonal therapy are generally not recommended except in specific circumstances. Testicular growth and potential for fertility improves when orchiopexy is performed before one year of age. For a palpable testis, a single incision approach is preferred over a two-incision orchiopexy. Laparoscopic orchiopexy is associated with a slightly lower testicular atrophy rate but a higher rate of long-term testicular retraction. One and two-stage Fowler-Stephens orchiopexy have similar rates of testicular atrophy and retraction. There is a higher relative risk of testicular cancer in UDT which may be lessened by pre-pubertal orchiopexy.

Comparison of the Detection and Ligation of Patent Processus Vaginalis Between Laparoscopy-Assisted Transscrotal Orchiopexy and Single Scrotal Incision Orchiopexy

This study aimed to compare the detection and ligation of patent processus vaginalis (PPV) between laparoscopy-assisted transscrotal orchidopexy (LATO) and single scrotal incision orchiopexy (SSIO) for low palpable undescended testis (UDT). We performed a retrospective medical record review of transscrotal orchidopexies performed for low palpable UDT at our institution from 2017 to 2019; 33 and 39 boys underwent LATO and SSIO, respectively. Data collection included patient demographics, incidence of PPV, operative time, and clinical outcomes. All 95 testes were delivered into the scrotum. There was no significant difference between the two groups with respect to patients' age, side, and mean operative time. The incidence of PPV in the LATO group was significantly higher than that in the SSIO group (56.52 vs. 34.69%, P = 0.04). The incidence of contralateral PPV in the LATO group was 45%. One patient in the SSIO group underwent unilateral PV ligation and laparoscopic exploration revealed bilateral PPV owing to metachronous contralateral hydrocele. One patient in the LATO group demonstrated obliterated PV in the initial transscrotal procedure, but an ipsilateral PPV was found in the latter laparoscopic procedure. In conclusion, LATO has a higher detection rate and higher ligation of the PPV than SSIO, suggesting that, LATO may help reduce recurrent PPV-related issues. However, long-term follow-up results are needed to evaluate the advantages and disadvantages in a larger case series.

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

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.

Single Median Raphe Scrotal incision Orchiopexy: A safe & feasible approach for fixation of Palpable Undescended testes

Background:

We wish to share our outcome of single median raphe scrotal incision orchiopexy (SMRSO) regarding safety & feasibility of technique by evaluating ease of access, conversion rate, duration of surgery, success rate, complications, and the need for redo-surgery.

Methods:

We retrospectively analyzed data of 277 orchiopexies performed in our department on 224 patients operated on between June 2016 to June 2019. SMRSO was considered for palpable testes that can be brought to the upper limit of the scrotum under anesthesia. The conventional inguinoscrotal approach was used for high lying testes. A median raphe incision was made to access & mobilize the testis on either side, ligation of processus vaginalis performed, and the testes secured in the scrotal pouch. The approach was utilized for both unilateral and bilateral orchiopexies. Follow-up done at one week, one month & six months to evaluate the outcome.

Results:

A total of 277 orchiopexies were performed in 224 patients. 237 (86%) orchiopexies were via the median raphe scrotal approach in 184 patients. Out of these, 53 cases had bilateral orchiopexies. 30 (11%) performed via a conventional inguinoscrotal approach and 10 (4%) by laparoscopic approach. The mean duration of surgery for SMRSO was 24 minutes for unilateral and 42 minutes for bilateral cases. Immediate postoperative complications included scrotal hematoma in three (1.6%) cases, Hematoma of the abdominal wall in one case, and scrotal edema in 4 (2 %) patients. All complications were treated conservatively & resolved. No wound infection or testicular atrophy was reported. Long-term complications included testicular ascend in three cases [1.6%].

Conclusion:

Single-incision Median Raphe Scrotal orchiopexy is an attractive alternative to the standard inguinoscrotal orchiopexy for palpable low lying undescended testes with a better cosmetic outcome.

Staged Fowler Stephens, Who Requires a Third Procedure?

PURPOSE OF REVIEW

The two-stage Fowler-Stephens orchiopexy is a well-described surgical approach for most pediatric urologists tackling the high intra-abdominal testis. Testicular ascent is a well-reported outcome of the surgery and a problem that could be fixed with a repeat procedure. The purpose of this review is to determine the rate of subsequent testicular ascent and repeat surgery after a two-stage Fowler-Stephens using best available evidence.

RECENT FINDINGS/RESULT

We selected 16 studies that pertained to our topic. 0-13% of testicles were deemed to be in an inappropriate position on follow-up (6-37 months). The definition of appropriate postoperative position varied between studies and rates of repeat procedures were sparsely available. Available data reports a repeat orchiopexy rate of 2.6-7.5% after two-stage Fowler-Stephens. Two-stage Fowler-Stephens orchiopexy is a highly successful surgical technique to manage high intra-abdominal testes. Rates of testicular ascent are difficult to ascertain due to varying definitions and small sample sizes. While repeat procedures are typically indicated, the actual rate of repeat orchiopexy is rarely reported and long-term outcomes following a third procedure is sparse.

Ambulatory Orchidopexy Is a Potential Solution to Improve the Rate of Timely Repair in Cryptorchid Boys: An 8 Year Retrospective Study of 4,972 Cases

Background: Cryptorchidism is the most common congenital anomaly in pediatric urology. Although early surgery on cryptorchid boys is recommended by pediatric urologists worldwide, the actual age at orchidopexy is often older than the recommended age. Our medical center has started performing ambulatory orchidopexy since March 2016 at the ambulatory surgery center. We aimed to investigate whether ambulatory orchidopexy can improve the timely repair rate. Methods: A retrospective analysis was conducted from 2012 to 2019 at our medical center. Ambulatory orchidopexy was started at our medical center on March 24, 2016. Boys born on or after September 24, 2015 were classified into the "with ambulatory medical resource" group, and boys born before September 24, 2014, were classified into the "without ambulatory medical resource" group. The timely repair rates were calculated and compared. Results: A total of 4,972 cryptorchidism cases were included in the final study. Approximately 33.0% of cryptorchid boys received timely surgery (orchidopexy by the age of 18 months), and only 6.8% of all cryptorchid boys underwent surgery before the age of 1 year. After the performance of ambulatory orchidopexy, the timely repair rate increased from 25.7 to 37.0% (P < 0.001), and the percentage of patients receiving surgery before the age of 1 year increased significantly from 3.5 to 8.6% (P < 0.001). The proportion of timely repair in patients with ambulatory medical resources was significantly higher than that in patients without ambulatory medical resources (15.6% vs. 58.2%, P < 0.001). Significant changes in the rate of surgery before 12 months of age were also found between the two groups (2.4% vs. 14.8%, P < 0.001). Conclusions: After the performance of ambulatory orchidopexy in our medical center, the rates of both timely repair and receiving surgery before the age of 1 year increased significantly. Ambulatory orchidopexy is a potential solution to improve the rate of timely repair in cryptorchid boys, and it is worthy of promotion in developing countries and regions.

Clinical and socioeconomic factors associated with delayed orchidopexy in cryptorchid boys in China: a retrospective study of 2423 cases

We investigated the associations of clinical and socioeconomic factors with delayed orchidopexy for cryptorchidism in China. A retrospective study was conducted on cryptorchid boys who underwent orchidopexy at Children's Hospital at Chongqing Medical University in China from January 2012 to December 2017. Of 2423 patients, 410 (16.9%) received timely repair by 18 months of age, beyond which surgery was considered delayed. Univariate analysis suggested that the laterality of cryptorchidism (P = 0.001), comorbidities including inguinal hernia/scrotal hydrocele (P < 0.001) or urinary tract disease (P = 0.016), and whether patients lived in a poverty county (P < 0.001) could influence whether orchidopexy was timely or delayed. Logistic regression analysis suggested that the following factors were associated with delayed repair: unilateral rather than bilateral cryptorchidism (odds ratio [OR] = 1.752, P < 0.001), absence of inguinal hernia or hydrocele (OR = 2.027, P = 0.019), absence of urinary tract disease (OR = 3.712, P < 0.001), and living in a poverty county (OR = 2.005, P < 0.001). The duration of postoperative hospital stay and hospital costs increased with the patient's age at the time of surgery.

A tailored surgical approach to the palpable undescended testis

INTRODUCTION

Orchiopexy for a palpable undescended testis can be approached through a traditional inguinal incision or trans-scrotally. Despite the possible advantages of the scrotal approach, including reduced postoperative pain and shorter recovery, it is not consistently advocated.

OBJECTIVE

The objective of this study was to present the experience with a tailored approach to orchiopexy based on physical findings.

STUDY DESIGN

This is an extended case series.

MATERIALS AND METHODS

The mobility of the testis as described at examination under anesthesia informs the choice of surgical approach. If a 'low' palpable testis (defined as testis that can be manipulated to the scrotum) was found, a scrotal approach was used. In cases of 'high' palpable testis (testis that cannot be manipulated to scrotum), the inguinal approach was used. Success was defined by location and size of the testis 3 months after surgery.

RESULTS

A total of 259 orchiopexies were performed in 181 boys (78 bilateral). Scrotal approach was used in 125 (48%) and inguinal in 134 (52%) orchiopexies. Operative time was significantly shorter for the scrotal approach, 25 min vs. 40 min for inguinal orchiopexy (P < 0.05). The overall success rate was 98% with no statistical difference between the groups. Three children from the inguinal group and two from the scrotal group required an additional procedure for persistent undescended testis. The rates of testicular atrophy and hypotrophic testis were higher in the inguinal group than the scrotal group (5/134 vs. 0/125; P < 0.05 and 17/134 vs. 6/126; P < 0.05, respectively).

DISCUSSION

The substantial cohort of patients selected for trans-scrotal orchiopexy experienced success rates and rates of atrophic and hypotrophic testis comparable with those found in the published literature. Furthermore, trans-scrotal operative times were significantly lower than those of inguinal procedures, and less patients required re-operation in the trans-scrotal group. Limitations of this study include significantly higher age at operation in trans-scrotal patients and a difficulty accurately classifying hypotrophic testes. Furthermore, the higher atrophic rate in the inguinal group vs. the scrotal group likely reflects the vulnerability of a testis that is located higher and not the superiority of the scrotal approach.

CONCLUSION

This tailored approach to a palpable undescended testis appears simple, safe, and effective, providing high success rate with marginal complications. It is considered a preference in cases of low undescended testis, whereas the standard two-incision inguinal orchiopexy may better serve those with high undescended testis.

Hydrocelectomy via scrotal incision is a valuable alternative to the traditional inguinal approach for hydrocele treatment in boys

Purpose

Few studies have explored the treatment of isolated communicating hydroceles via scrotal incision. We prospectively evaluated the surgical outcomes of such treatment in boys with hydroceles compared with that using traditional, inguinal incision hydrocelectomy.

Materials and Methods

Of 347 boys aged 0–12 years who were diagnosed as hydrocele on ultrasonography, 173 boys were assigned to the scrotal incision hydrocelectomy group (group I, n=173) and 172 boys were assigned to the traditional inguinal incision hydrocelectomy group (group II, n=172), and finally 156 boys in group I and 156 boys in group II were included in this study. Surgical outcomes, including postoperative complications and hydrocele relapse rates, were compared between groups.

Results

The overall success rates were similar in both groups (group I, 96.8%; group II, 89.1%; p=0.740). The operation time and hospital stay were significantly shorter in group I (30.94±3.95 minutes and 3.94±0.30 days) than in group II (38.02±7.12 minutes and 4.24±0.99 days; p<0.001 and p=0.009, respectively). The postoperative complication rate was lower in group I than in group II (3.2% vs. 10.9%, p=0.740).

Conclusions

Scrotal incision hydrocelectomy in boys was associated with shorter operative time and hospital stay, and a lower postoperative complication rate, than was the inguinal incision approach. The scrotal incision technique might be an easy and effective alternative treatment when used to treat hydroceles in boys as well as inguinal incision approach.

Canadian Urological Association-Pediatric Urologists of Canada (CUA-PUC) guideline for the diagnosis, management, and followup of cryptorchidism

Cryptorchidism is one of the most common congenital anomalies in males, characterized by inability to palpate the testicle in the expected normal anatomical position (i.e., within its respective hemi-scrotum). It represents an abnormality of testicular descent and development associated with long-term concerns, including infertility, hypogonadism, and development of neoplasms.

Health Disparities in the Appropriate Management of Cryptorchidism

OBJECTIVE

To assess regional practices in management of cryptorchidism with regard to timely fixation by the current recommended age of 18 months.

STUDY DESIGN

A retrospective study was performed. Charts of all patients who underwent surgical correction for cryptorchidism by a pediatric general surgeon or urologist within a tertiary pediatric hospital in an urban setting were systematically reviewed.

RESULTS

We identified 1209 patients with cryptorchidism. The median age of surgical correction was 3.7 years (IQR: 1.4, 7.7); only 27% of patients had surgical correction before 18 months of age. Forty-six percent of our patients were white, 40% were African American, and 8% were Hispanic. African American and Hispanic patients were less likely to undergo timely repair (P?=?.01), as were those with public or no insurance (P?<?.0001). A majority (72%) of patients had no diagnostic imaging prior to surgery. A majority of patients had palpable testes at operation (85%) and underwent inguinal orchiopexy (76%); 82% were operated on by a pediatric urologist. Only 35 patients (3%) experienced a complication; those repaired late were significantly less likely to develop a complication (P?=?.03). There were no differences in age at time of surgery by surgeon type.

CONCLUSIONS

A majority of our patients were not referred for surgical intervention in a timely manner, which may reflect poor access to care in our region. Public and self-pay insurance status was associated with delayed repair. Education of community physicians and families could be potentially beneficial.

Is inguinal orchidopexy still a current procedure in the treatment of intraabdominal testis in the era of laparoscopic surgery?

PURPOSE

To report our experience in surgical management of nonpalpable intraabdominal testis (NPIT) by inguinal orchidopexy without division of the spermatic vessels.

METHODS

We reviewed the records of NPIT patients who underwent orchidopexy between 2012 and 2015. All patients were evaluated ultrasonographically. When the testis was not detected ultrasonographically, a laparoscopic exploration was performed. If the testis was found on laparoscopy, surgery was resumed through an inguinal incision. A follow-up was performed at 1week, 1, 3 and 6months.

RESULTS

Twenty-one NPIT patients were treated, mean age 21.0±11.7months. Ultrasound identified 15 cases of NPIT (71%); diagnostic laparoscopy was performed in 6 (29%). All patients underwent an inguinal orchidopexy. At 1week, four testes were in a high scrotal position. At 6months follow-up, one testis was in a high scrotal position and one retracted up to the external inguinal ring. No atrophy was recorded.

CONCLUSIONS

Despite several attempts to find a surgical technique without any significant complications, all described procedures failed to meet the target. In our experience, inguinal orchidopexy is a safe, reliable and successful surgical procedure for the management of NPIT. It should be preferred to a technique requiring vascular division, burdened with a higher incidence of atrophy.

Cryptorchidism: A practical review for all community healthcare providers

Cryptorchidism is one of the most common congenital anomalies of the male genitalia, occurring in 1% of boys by the age of one year. Even though the etiology of cryptorchidism is multifactorial, management has evolved with the clear recognition that hormonal treatment is not effective and surgery between 6-18 months of age leads to better testicular outcomes. Diagnostic laparoscopy is considered the standard approach for management of non-palpable testes, and can be combined with one or two-stage orchidopexy, with up to 80-90% success rates. This review discusses the natural history of retractile testicles, indications for hormonal treatment and orchidectomy, ultrasound's role as a diagnostic tool, risks of infertility and testicular cancer, and surgical techniques for inguinal and intra-abdominal testes.

[Congenital undescended testis: Should open processus vaginalis have any impact on the elected surgical approach?]

PURPOSE

Compare the position of the undescended testis at clinical examination and under general anesthesia with the patency of an open processus vaginalis.

PATIENTS AND METHODS

We included children from 2 to 18 years of age operated for a unilateral or bilateral undescended testis between January 2006 and April 2014 at the Annecy Genevois hospital, France. The analysis was conducted considering that the individual was the testis. Testicular position before surgery, under general anesthesia and patency of open processus vaginalis as a surgical finding were prospectively recorded.

RESULTS

Three hundred and six children were included. The analysis was conducted over 401 testes. The position at clinical examination was significantly linked to a persistent open processus vaginalis (P=0.0045). Over the 282 testes considered as candidate for Bianchi's procedure, as to say intra- or supra-scrotal under general anesthesia, 154 had a persistent processus vaginalis (55%).

CONCLUSION

There is a link between a persistent processus vaginalis and the location of the undescended testis which should encourage us not to neglect the inguinal approach, and eventually to question the relevance of Bianchi's procedure.

Single scrotal incision orchiopexy versus the inguinal approach in children with palpable undescended testis: a systematic review and meta-analysis

PURPOSE

We performed a systematic review and meta-analysis to compare the efficacy and safety between single-incision, transscrotal orchidopexy, and the traditional inguinal orchidopexy in children.

METHODS

A systematic search of the electronic databases was conducted to identify studies compared the transscrotal orchidopexy (SO) and inguinal orchidopexy (IO) for children. Parameters, such as operative time, the incidence of patent processus vaginalis, and postoperative complications, including wound infection, testicular atrophy, testicular reascent, hernia, or hydrocele, were pooled and compared by meta-analysis.

RESULTS

Among the 1376 children with palpable undescended testes (UDTs) included in the eight studies, 697 had received SO and 679 IO. There were shorter operative times with the SO approach compared with IO. However, no significant difference was found between SO and IO in the incidence of patent processus vaginalis and postoperative complications, including wound infection, testicular atrophy, testicular reascent, and hernia.

CONCLUSION

SO is a safe and effective surgical approach alternative to IO for pediatric UDTs. Compared with IO, SO has the advantage of shorter operative times. Besides, the incidence of postoperative wound infection may be slightly lower in SO. We suggest that SO should be considered as an acceptable option for children with UDTs.

Outcome Analysis of Redo Orchiopexy: Scrotal vs Inguinal

PURPOSE

Redo orchiopexy after previous surgery is technically challenging and requires skills and care to ensure preservation of cord structures. We report our experience with redo orchiopexy in children.

MATERIALS AND METHODS

We retrospectively reviewed patients who had undergone redo orchiopexy between January 2004 and May 2015. Variables evaluated included primary procedure, type of redo procedure, operative time, shift of surgical route, operative and postoperative complications, and testicular location at last followup.

RESULTS

A total of 3,384 orchiopexies were performed during the study period, with 61 children (1.8%) requiring redo orchiopexy. Mean ± SD patient age at redo orchiopexy was 6.4 ± 3.6 years (range 1.5 to 17.1) and average followup was 24.9 months (2.1 to 99.6). The primary surgical procedure preceding redo surgery was inguinal orchiopexy in 45.9% of the patients, scrotal orchiopexy in 13.1% and laparoscopy in 13.1%, and 27.9% of patients were status post inguinal surgery (hernia/hydrocele repair). Redo surgery was performed by inguinal approach in 33 patients, while 28 children underwent a scrotal approach. There was no statistical difference in intraoperative and postoperative complication rates for the 2 approaches (p = 0.52 and p = 0.26, respectively). However, there was a statistically significant difference in overall operative time between approaches (p = 0.003) with scrotal orchiopexy being significantly shorter (53.1 minutes) compared to inguinal orchiopexy (84.6).

CONCLUSIONS

Scrotal and inguinal orchiopexy appear to be viable in managing secondarily ascending testes, with the scrotal approach offering some advantage in terms of length of procedure.

Long-Term Outcome of Low Scrotal Approach Orchiopexy without Ligation of the Processus Vaginalis

PURPOSE

We performed low scrotal approach orchiopexy in patients with prescrotal cryptorchidism. The processus vaginalis was not ligated if it was not widely patent. We retrospectively evaluated the long-term outcomes of low scrotal approach orchiopexy without processus vaginalis ligation.

MATERIALS AND METHODS

A total of 137 patients (227 testes) were diagnosed with prescrotal cryptorchidism between October 2009 and April 2014. All patients underwent low scrotal approach orchiopexy. Mean age at surgery was 34.9 months. The processus vaginalis was deemed to be not widely patent when a sound could not be passed into the abdominal cavity through the internal inguinal ring, and the processus vaginalis was not ligated in such cases.

RESULTS

Intraoperative findings revealed that the processus vaginalis was widely patent in 10 testes and was not widely patent in 217. A widely patent processus vaginalis was closed via scrotal approach in 5 testes, while an inguinal approach was necessary in 5. Median followup was 44 months (range 20 to 73). Postoperative complications included reascending testis in 1 case where an inguinal approach was necessary. No patient manifested testicular atrophy or inguinal hernia.

CONCLUSIONS

Low scrotal approach orchiopexy is a useful and safe procedure for treating patients with prescrotal cryptorchidism. Ligation is unnecessary when the processus vaginalis is not widely patent.

The interscrotal approach to inguinoscrotal pathologies

Objective

To determine the efficiency of the interscrotal approach to inguinoscrotal pathologies.

Patients and methods

We report the use of the interscrotal approach in 21 boys, from September 2012 to November 2013, operated using an interscrotal access through a vertical incision on the median raphe.

Results

The approach was used for bilateral inguinal hernia (48%), bilateral ectopic testis (19%), torsion of the spermatic cord (19%), testicular biopsy (10%) and webbing of the penis (5%).

Conclusion

Inter-scrotal access is an option for inguinoscrotal pathologies, with the advantages of a single incision, much less dissection and disruption of tissue, and greater comfort for the ‘day-case’ child.

[Comparison of the inguinal and scrotal approaches for the treatment of cryptorchidism in children]

INTRODUCTION

The single scrotal incision orchidopexy was described by Bianchi in 1989. Despite its popularity, the place of this technique in the treatment of cryptorchidism in children is still unclear.

AIM OF THE STUDY

To evaluate and compare the outcomes of the conventional inguinal approach and the scrotal approach for the treatment of palpable undescended testis in children.

METHODS

A prospective study for all patients with palpable undescended testis undergoing orchidopexy between January 2011 and December 2013 was conducted. Totally 200 patients were randomly divided into two groups: group 1: two incisions inguinal approach (80 patients, 100 testis); group 2: single scrotal incision approach (89 patients, 100 testis).

MAIN RESULTS

The patients' mean age was 53.9±13 months in group 1 and 45.8±9 months in group 2. There was no statistical difference between the two groups in terms of patient age (P=0.8) and location of the undescended testis (P=0.359). Operative time was statistically significantly lower in the scrotal group (P<0.05). There was a significant difference in the complications rates between the two groups.

CONCLUSION

The single scrotal incision orchidopexy is safe and effective for undescended testicles palpable in the inguinal canal or in high scrotal position.

Herniotomy in resource-scarce environment: Comparison of incisions and techniques

BACKGROUND

There are various methods for surgical treatment of hernia and hydrocele in children with variable cost-effectiveness, recovery and cosmetic outcomes. This study analyses our experience with mini-incision/invasive herniotomy in children in resource-limited centre.

MATERIALS AND METHODS

Seven hundred and eighty-four n = 784 patients underwent herniotomy via conventional and mini-invasive methods were assigned into Group A and Group B. Three hundred and seventy-six n = 376 (47.95%) in Group A while four hundred and eight n = 408 (52.04%) in Group B. Eight hundred and seventeen (817) herniotomy was performed. Demographic data, hernia/hydrocele sides, volume of surgical suture used, surgery duration, and complications analysed.

RESULTS

Right side hernia and/or hydrocele were 464 (59.18%). 287 (36.60%) had left sided while 33 (4.21%) had bilateral hernia and/or hydrocele. There were 14 bilateral hernia repair in Group A and 19 in Group B. The lengths of operation time for unilateral repair ranged from 14 to 54 min in Group A (median, 23 min) and 7-44 min in Group B (median, 15 min) with a mean surgical duration of 15.48 ± 4.16 min in Group B versus 23.41 ± 5.94 min in Group A (P < 0.001) while the range of the lengths of operation time for bilateral repair in Group A was 20-54 min (median, 36) and 12-30 min (median, 21) in Group B with a mean duration of 36.35 ± 9.89 min in Group A versus 20.42 ± 4.83 min in Group B P = 0.00563. 376 sachets of 45 cm suture material were used in Group A versus 137 in Group B. There were total of 87 (23.13%) complications in Group A versus 3 (1.47%) in Group B P = 0.000513. Superficial wound infection and abscess were 9 (2.36%) and 16 (4.25%) in Group A versus none (0) in Group B.

CONCLUSION

Mini-incision/invasive herniotomy in children and adolescents is fast, cost-effective with satisfactory cosmetic outcome and limited complications.

Orchiopexy through a single high transverse scrotal incision

BACKGROUND

Palpable Undescended Testis (PUT) represents a common paediatric problem in many premature and some mature infants. There are several surgical techniques to correct PUT either through combined inguinal and scrotal incision or single transverse scrotal incision. This study assessed single high transverse scrotal incision for the management of PUT as regards to feasibility, postoperative success and final cosmetic results.

MATERIALS AND METHODS

One hundred twenty patients were managed at the Paediatric Surgery Department of Tanta University Hospital with PUT during the period from March 2010 to March 2014. They were all operated at the age of 6-12 months. We excluded recurrent cases, and cases older than 12 months. Through high transverse scrotal incision, the layers were divided, and the canal entered through the external ring, dissecting the PUT and bringing it through the incision. Hernia sac, if present, was ligated at the neck. Creation of the dartos pouch was then made through the same incision. All infants were followed-up at 1 month, 2 months and 6 months to detect any re-ascended cases, testicular atrophy and the final cosmetic appearance.

RESULTS

A total of 140 PUTs were operated upon in 120 patients. PUT was bilateral in 20 patients, right-sided in 65 cases and left-sided in 35 cases. Thirty testes were located at the external ring; the others were located within the inguinal canal. No cases needed a redo operation, and there was no case of postoperative testicular atrophy.

CONCLUSION

Single high transverse incision was sufficient to deal with PUT especially, in young infants (age 6 months) with no need for conversion in most cases to the traditional two incisions technique, and good long term follow-up and a better cosmetic results.

Single scrotal-incision orchidopexy for palpable undescended testis in children

OBJECTIVE

To evaluate the single scrotal-incision orchidopexy (SSIO) technique in patients with an undescended testis palpable in the inguinal canal or below the external inguinal ring.

PATIENTS AND METHODS

Between January 2011 and December 2013 we performed 100 SSIOs in 89 patients. The mean (range) follow-up was 9 (3-36) months.

RESULTS

In 88 testes the SSIO was performed with no difficulties. In four patients an additional dissection by opening the external ring and canal was necessary; none of these patients developed an inguinal hernia after surgery. In eight patients conversion to an inguinal approach was necessary because of difficulty in controlling the hernial sacs and inadequate mobilisation. At the follow-up assessment, of the 89 patients, none developed testicular atrophy, one (1%) had wound dehiscence and four (5%) had a scrotal haematoma. There was no statistically significant difference between the testicular size at baseline and that during the follow-up. At 3 months after surgery the overall cosmetic result was excellent.

CONCLUSION

The SSIO is minimal-access surgery allowing less dissection, less discomfort for the patient, rapid healing, excellent cosmetic results and a good success rate. This technique is safe and effective for undescended testes palpable in the inguinal canal or below the external inguinal ring.

Primary new-onset hydroceles presenting in late childhood and pre-adolescent patients resemble the adult type hydrocele pathology

AIM

The aim of this study was to investigate the presence of a patent processus vaginalis (PPV) in children of late childhood and pre-adolescence presenting with new onset hydrocele.

MATERIAL AND METHODS

All males with hydrocele presenting at our department from January 2011 to January 2013 were followed. Patients with secondary hydroceles were excluded. Demographic data, medical history, clinical symptoms and signs relative to their pathology and U/S findings were recorded. According to their indications, patients were either operated or followed up. Patients surgically treated, consisted our study group.

RESULTS

Sixty patients were identified. Thirteen were followed until resolution of their hydrocele. Forty-seven patients were surgically treated. Twenty-seven had right sided hydrocele (57.44%), 13 had left sided hydrocele (27.66%) whereas in 7 patients the hydroceles were bilateral (14.9%). All patients were operated by an inguinal approach. In all 9 patients (19.14%) presenting with new-onset hydrocele at the age >10 years (range: 10-15 years), intraoperative exploration did not reveal a PPV. All patients were followed at least for 6 months post-operatively.

CONCLUSION

Early evidence shows that primary new onset hydroceles presenting in late childhood and pre-adolescence seem to be non-communicating and resemble the adult type hydrocele pathology.

Laparoscopy in the surgical management of the non-palpable testis

INTRODUCTION

To demonstrate that laparoscopic intervention should be considered as the initial surgical approach in the management of the non-palpable testis (NPT).

METHODS

From 2007 to 2011, 100 testicular units underwent same surgeon laparoscopic management for NPT. Diagnostic laparoscopy was performed in all NPT and intra-abdominal testes (IAT) were managed by laparoscopic orchiopexy if low, laparoscopic Fowler-Stephens technique if high, and laparoscopic orchiectomy if atrophic. Percutaneous access to the abdomen was performed in most cases and laparoscopic management was performed with three 5 mm ports. We compared patient's age, race, pre/post-operative exam, pre-operative work up, and IAT location upon laparoscopic intervention with surgical outcome. Fisher's exact test for two independent proportions was used for statistical analysis and reported our results.

RESULTS

One hundred testicular units underwent diagnostic laparoscopy for NPT. All patients were from Puerto Rican descent. 55.0% were found to be intra-abdominal and were subdivided into groups according to surgical intervention. Mean post-operative follow-up was 24 months. Patients 24 months of age or younger undergoing diagnostic laparoscopy for NPT had a statistically significant probability of resulting in successful laparoscopic orchiopexy as opposed to laparoscopic orchiectomy due to an atrophied IAT (n = 55 testicular units, p < 0.05). No laparoscopic related complications were reported.

CONCLUSION

Our findings support the use of an initial laparoscopic approach in the NPT as the majority of these patients will have IAT, avoiding unnecessary inguinal and scrotal explorations. We also recommend that patients with IAT should undergo laparoscopic orchiopexy prior to 2 years of age to increase probability of successful management. Further studies focusing in patients with NPT are needed in the future to confirm our findings.

Comparison of the inguinal and scrotal approaches for the treatment of communicating hydrocele in children

The inguinal approach is used for the treatment of hydrocele in the pediatric population. Although studies on scrotal orchiopexy have mentioned hernia or hydrocele repair through the same scrotal incision as a part of an orchiopexy procedure, there are a few studies reporting the treatment of isolated communicating hydrocele through a scrotal incision. We retrospectively evaluated and compared the outcomes of inguinal and scrotal approaches for the treatment of communicating hydrocele in boys. The classical inguinal and scrotal approaches to the treatment of communicating hydrocele were performed on 46 and 30 testicular units (in 43 boys and 27 boys, respectively). The patients' charts were reviewed to assess the operative times as well as the immediate and long-term complications during follow-up periods. The patients' ages ranged from 1 year to 8 years (3.6 ± 2.0 years) in the inguinal group and from 1 year to 10 years (mean 4.6 ± 2.8 years) in the scrotal group. Operative time was significantly lower in the scrotal group (p < 0.0001). The early minor complication rate did not differ between the two groups. Furthermore, there were no major complications noted. None of the patients had hydrocele recurrence after a mean follow-up of 6 months. The advantages of the scrotal approach for the treatment of communicating hydrocele are as follows: it is well tolerated, simple, and cosmetically appealing, and it has a short operative time in comparison with the standard inguinal approach. The scrotal incision technique is an effective alternative in communicating hydrocele treatment.

One third of patients with a unilateral palpable undescended testis have a contralateral patent processus

PURPOSE

The purpose of this study was to determine the incidence and predictive factors associated with a contralateral patent processus vaginalis in boys with a unilateral palpable undescended testis.

METHODS

We retrospectively reviewed the records of 77 consecutive boys (median age, 15 months; range, 5 months to 17.7 years) who had undergone orchiopexy for a unilateral palpable testis. At inguinal orchiopexy, an 8F feeding tube and a 70° adult cystoscope lens were placed into the peritoneum through the hernia sac, and the contralateral internal ring was inspected. The clinical factors that might predict the presence of a contralateral patent processus vaginalis were determined.

RESULTS

The overall rate of a contralateral patent processus vaginalis was 34% in those with a significant ipsilateral hernia sac. After considering age, side, prematurity, location, and volume of the undescended testis, only the boys with a testis distal to the external ring compared with those with testes lying within the inguinal canal had statistically increased odds of a patent contralateral processus vaginalis (odds ratio, 3.1; 95% confidence interval, 1.08-9.08).

CONCLUSION

Approximately one third of boys with a unilateral palpable undescended testis will have a contralateral patent processus vaginalis as determined by transinguinal laparoscopy. The rate is higher (52%) if the undescended testis was distal to the external ring. Both the etiology and significance of this contralateral finding are unknown.

Single scrotal incision for repair of bilateral inguinal hernias in boys

PURPOSE

Single scrotal incision for repair of bilateral inguinal hernias in boys is a new and attractive approach. However, the advantages and drawbacks of this approach have not been fully discussed in the literature and it has not been widely accepted as a standard procedure for repair of bilateral inguinal hernias. We develop the median raphe approach and this study is aimed to clarify the outcomes of this new technique.

METHODS

From January 2006 to December 2010, we studied 114 boys with bilateral inguinal hernias who underwent trans-scrotal repairs using median raphe incisions. The follow-up durations ranged from 12 to 36 months. The operation time and morbidity of this approach were compared to those of 91 boys who underwent conventional bilateral inguinal incision herniorrhaphy from January 2001 to December 2005.

RESULTS

The operation times were equal in both approaches. The incidence of stitch abscesses was a little higher in scrotal incision group. All the boys with the scrotal approach had excellent cosmetic results.

CONCLUSION

The median raphe approach for bilateral inguinal hernia repair is a good alternative to the conventional method for boys.

Scrotal fixation in the management of low undescended testes

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.

Single scrotal incision orchiopexy for children with palpable low-lying undescended testis: early outcome of a prospective randomized controlled study

Purpose

We prospectively evaluated the surgical outcomes of single scrotal incision orchiopexy in children with a palpable undescended testis compared with the traditional two incision orchiopexy.

Materials and Methods

A total of 398 orchiopexies (292 children) were included and randomly assigned to the single scrotal incision orchiopexy group (Group I, 147 children, 201 testes) or the traditional inguinal incision orchiopexy group (Group II, 145 children, 197 testes). The final number of patients enrolled (excluding those lost to follow-up) was 107 children (146 testes) in group I and 105 children (141 testes) in group II. Success was defined as no complications, postoperative intrascrotal location of the testis, and no conversion to the traditional inguinal approach. Surgical outcomes and complications were compared between the two groups. Testicular location, complications, and subjective satisfaction rate were assessed at the follow-up evaluation at least 12 months postoperatively.

Results

The overall success rate in group I was 92.5% in 135 of 146 testes; the remaining 9 testes required conversion to traditional two incision orchiopexy. In group II, orchiopexy was successful in 136 of 141 testes (96.5%). The operation time and hospital stay were significantly shorter in group I (40.5±25.9 minutes, 2.1±0.8 days) than in group II (62.3±35.6 minutes, 2.5±0.7 days), respectively (p<0.001, p=0.03). Postoperative complications were found in two cases (hematoma, wound dehiscence) in group I and in one case (wound dehiscence) in group II; all cases with complications recovered with conservative care. The subjective rate of satisfaction with the cosmetic result was 96.6% in group I and 96.5% in group II (p=0.97).

Conclusions

We conclude that single scrotal incision orchiopexy is a simple technique that is associated with a shorter operation time and hospital stay than the traditional method and that is more feasible cosmetically.

20 years of transcrotal orchidopexy for undescended testis: results and outcomes

BACKGROUND

The role of the transcrotal approach to the undescended testis remains controversial despite its increasing popularity. The authors update their previous published series and review the literature on this subject, aiming to delineate the value of this technique.

METHODS

The authors performed a retrospective review of the transcrotal primary orchidopexy carried out to treat palpable undescended testis at Royal Manchester Children's Hospital between 1993 and 2005. A structured review of literature published since the proposal of this technique was also performed.

RESULTS

122 procedures were included. The transcrotal approach was successfully completed in 119 (97.5%). Additional groin incision was needed in three (2.5%) to further mobilize the spermatic cord. No immediate complications were recorded and 8.4% required a reoperative procedure. On review of the literature, a total of 16 articles were discovered spanning 1695 transcrotal procedures, including the previously published authors' experience. On combining the data, the transcrotal approach required an additional groin incision in 4.4% of cases, 1.6% experienced immediate and/or early complications, and the overall recurrence rate was 2.0%.

CONCLUSIONS

Transcrotal orchidopexy for the treatment of palpable undescended testes is a safe procedure with a long-term success rate comparable to the two-incision approach.

Cryptorchidism: pathogenesis, diagnosis, treatment and prognosis

Cryptorchidism is a common genital anomaly diagnosed at birth or during childhood. Genetic and/or environmental factors that alter expression or function of hormones crucial for testicular descent, insulin-like 3, and testosterone, may contribute to cryptorchidism. When identified at birth, surgical treatment is indicated by 6 months of age if testes fail to descend, or at the time of diagnosis in older children. A laparoscopic approach is preferred for abdominal testes. Early surgical therapy may reduce the risk of subfertility and/or malignancy.

Management of hydrocele in adolescent patients

Hydrocele is defined as an abnormal collection of serous fluid in the potential space between the parietal and visceral layers of the tunica vaginalis. In the majority of affected adolescents, hydrocele is acquired and is idiopathic in origin. The pathogenesis of idiopathic hydrocele is thought to be an imbalance in the normal process of fluid production and reabsorption. The diagnosis is usually clinical. Taking a thorough history is essential to rule out any fluctuation in size, which is an indication of a patent processus vaginalis. Scrotal ultrasonography is mandatory in nonpalpable testicles to rule out a subtending testicular solid mass requiring inguinal exploration. Otherwise, open hydrocelectomy via a scrotal incision is the standard treatment of idiopathic hydroceles. The second most common cause of hydrocele in adolescents is varicocelectomy. The risk of hydrocele formation is higher with non-artery-sparing procedures or those performed without microsurgical aid, and in surgery requiring cord dissection. If hydrocele occurs after varicocelectomy, initial management should include observation with or without hydrocele aspiration. Large persistent hydroceles are best served by open hydrocelectomy.

"Open" minimally invasive surgery in pediatric urology

Minimally invasive surgery (MIS) offers alternative operative approaches to standard open surgical techniques. However, MIS has been defined primarily as substituting laparoendoscopic alternatives for the traditional open surgical approach. The concept of MIS methodology may also be applied to open surgery in an effort to decrease incision size, potentially reduce morbidity and enhance convalescence, without compromising 'gold standard' outcomes. Pediatric urological applications of open MIS include pediatric renal surgery, ureteral reimplantation, ureteral surgery, inguinal-scrotal and genital surgery. A thorough review of the pediatric urology literature was performed and studies were identified describing open MIS, including outcomes and complications.

The prevalence, postnatal descent, and complications of undescended testes among children who underwent neonatal circumcision in Benin City, Nigeria

BACKGROUND/PURPOSE

The prevalence, age at postnatal descent, and age at which complications set in and, therefore, prevented by orchidopexy in undescended testes are controversial. This study sought to determine the prevalence, age at postnatal descent, and age at which complications occurred in undescended testes.

METHODS

A prospective study was done on children who underwent neonatal circumcision at the University of Benin Teaching Hospital, Benin City, and Leadeks Medical Centre, both in Edo state, Nigeria, between January 2002 and December 2007. Those diagnosed with undescended testes were recruited for the study and followed up at the surgical outpatient clinic for 2 years; findings were documented on a structured proforma.

RESULTS

A total of 178 neonates aged between 5 and 28 days (mean, 7.6 +/- 4.2 days) and mean weight 3.9 +/- 1.8 kg among 6180 children circumcised had 186 undescended testes. On follow-up, 65 (34.9%) testes mainly among preterm neonates (P = .2450) fully descended within 7 months with no testicular descent recorded thereafter. Prevalence rates of 2.9% in neonates and 1.8% at 2 years old were recorded. Reduction in testicular volume, epididymoorchitis, and testicular torsion were recorded in 52 (28%) undescended testes between 12 and 24 months on follow-up.

CONCLUSION

Neonates with undescended testis should be observed for postnatal descent at least 7 months but may be offered orchidopexy before 1 year.

Hydrocele in the pediatric patient: inguinal or scrotal approach?

PURPOSE

The recommended approach for repairing hydrocele in children is inguinal to address a patent processus vaginalis. Hydrocele repair in adults is performed with a scrotal incision. We identified an age above which a significant percent of children had noncommunicating hydroceles, justifying a scrotal approach.

MATERIALS AND METHODS

A retrospective chart review was performed of children undergoing hydrocele repair at our institution between 1998 and 2006. Operative reports were reviewed by 2 investigators and intraoperative findings were recorded for statistical analysis relating age and findings at the time of the procedure using logistic regression and ROC analysis. Laterality and recurrence rates were also noted.

RESULTS

In this retrospective chart review 82.1% of hydroceles in children older than 10 years had intraoperative findings consistent with noncommunicating hydrocele and 86.4% in children older than 12 years were noncommunicating. One hydrocele in the age group older than 12 years was communicating and the history was suggestive of communication. Age was significantly associated with a patent processus vaginalis (OR 0.783, p <0.0001).

CONCLUSIONS

It is possible in children older than 12 years to repair hydroceles through a scrotal incision unless the clinical history is suggestive of a communication. Children younger than 12 years should undergo inguinal exploration for hydrocele repair.
