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.

Laparoscopic-Assisted Scrotal Approach for the Treatment of Inguinal Cryptorchidism with Patent Processus Vaginalis: Clinical Efficacy Analysis

Objective: This study aimed to compare the clinical outcomes of two surgical approaches, laparoscopic-assisted scrotal incision and conventional inguinal-scrotal incision, for treating cryptorchidism with unobliterated processus vaginalis. Methods: Clinical data from 60 pediatric patients with inguinal cryptorchidism who were admitted to our institution between January 2018 and January 2022 were retrospectively analyzed. Depending on the surgical technique used, the patients were split into two groups: the laparoscopic group (n = 30) underwent a laparoscopic-assisted scrotal incision, whereas the conventional group (n = 30) underwent a conventional inguinal-scrotal incision for testicular descent and fixation. The length of the procedure, intraoperative blood loss, and the typical hospital stay following the procedure were compared between the two groups. Also assessed was the frequency of postoperative complications including wound infection and hematoma development. Results: The laparoscopic group demonstrated a notably shortened average surgical duration compared with the traditional group, and this discrepancy held statistical significance (P = .017). Moreover, the laparoscopic approach resulted in a reduced volume of intraoperative blood loss, with a statistically significant distinction (P = .002), along with a decreased average length of hospital stay after surgery, also statistically significant (P = .009). Testicular retraction, atrophy, inguinal hernias, or hydrocele were not present in any group. Although the difference between the laparoscopic and open groups was not statistically significant (P > .05), the laparoscopic group saw a reduced frequency of scrotal hematoma. The frequency of wound infection was also decreased in the laparoscopic group compared with the open group, although there was no statistically significant difference (P > .05). Conclusion: The laparoscopic-assisted scrotal incision approach for testicular descent and fixation offers precise localization of cryptorchidism, reduced surgical trauma, shorter postoperative recovery time, and results in smaller scars with minimal tissue damage. The procedure showcases enhanced overall clinical effectiveness, fewer postoperative complications, heightened safety, and superior cosmetic outcomes.

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.

Epidemiology, Diagnosis and Therapeutic Approaches of Cryptorchidism at the Panzi General Hospital, DR Congo: A 5-year Retrospective Study

Background

Cryptorchidism is a common congenital malformation characterized by unilateral or bilateral undescended testis in the scrotum. It is a common disease in pediatric urology although the prevalence is yet to be determined in the East DR Congo. The aim of this study was to describe the prevalence, clinical and therapeutic features of cryptorchidism at the Panzi General Hospital.

Methods

Medical records of patients who underwent pediatric surgery between January 2011 and December 2016 were reviewed. The prevalence of cryptorchidism, associated malformations, sociodemographic features of patients and therapeutic protocols were examined. Collected data were analyzed using SPSS software.

Results

A total of 5066 children were received during the study period in the service, of which 76 suffered from cryptorchidism giving a prevalence of 1.50% and an annual incidence of 12.70. Unilateral cases were found in 53(69.74%) patients among which 66.04% and 33.96% had unilateral right and left cryptorchidism respectively. Cryptorchidism was associated with other malformations in 71.1% of patients. The age of patients ranged from 0 to 15 years and 78.9% were older than two years. Surgery was the only therapeutic approach and fixation of cryptorchid testis in dartos through inguinal incision was the preferred therapeutic used method.

Conclusion

This study indicates that cryptorchidism is a relatively common and neglected disease in the Est-DR Congo, due to late consultation. Therefore, the local population and pediatricians should be sensitized on scrotal palpation techniques in order to shorten the consultation delay and prevent testis damages.

Trans-scrotal Incision Approach versus Traditional Trans-scrotal Incision Orchiopexy in Children with Cryptorchidism: A Randomized Trial Study

Background:

Although undescended testis (UDT) is the most prevalent malformation in male neonates, the best mode of UDT treatment remains controversial. This study aimed to compare trans-scrotal incision approach with traditional trans-scrotal incision orchiopexy in children suffering from cryptorchidism.

Materials and Methods:

This single-blind randomized clinical trial was done on 100 children with UDT who needed surgery. The participants were alternately undergoing trans-scrotal incision orchiopexy (Group I) and traditional inguinal incision orchiopexy (Group II). The success rate and incidence of postoperative complications were evaluated 1 week and 1 month and 6 months after the operation in the two groups.

Results:

Both the groups were similar in baseline characteristics including age and laterality (P > 0.05). There was no significant difference between the two groups in terms of the incidence of wound infection, testicular atrophy, testicular hypotrophy, and relapse (P > 0.05). In addition, the success rates were 98% in Group I and 94% in Group II (P > 0.05).

Conclusion:

Both surgical methods have a high success rate, and there is no significant difference in the incidence of complications; however, in terms of beauty, satisfaction, and shortening the duration of surgery and the duration of hospitalization, trans-scrotal approach was more successful than the traditional method.

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.
