Comparison of Scrotal Orchiopexy Versus Traditional Inguinal Orchiopexy for Palpable Undescended and Retractile Testis in Children: Insights from a Greek Surgical Center

TL;DR

This study compares two surgical techniques for treating undescended or retractile testes in children and finds that the single-scrotal approach has fewer complications.

Contribution

The study provides new insights into the safety and effectiveness of scrotal orchiopexy compared to traditional inguinal orchiopexy in a single pediatric center.

Findings

Scrotal orchiopexy had fewer postoperative complications compared to the two-incision inguinal approach.

Congenital cryptorchidism was identified as a risk factor for surgical complications.

Single-scrotal orchiopexy is suggested as a safer option for palpable undescended testes.

Abstract

Introduction/Purpose: Congenital cryptorchidism and retractile testis represent the most commonly presented abnormalities of the male genitourinary system. Orchiopexy is the surgical treatment for both conditions and can be performed either via the conventional two-incision surgical approach or via a singular scrotal incision. The present study firstly investigated the complications associated with each orchiopexy approach in a single-center pediatric surgical department and secondly compared the surgical outcomes in children with congenital cryptorchidism or retractile testes. Methodology: A retrospective analysis was conducted in pediatric patients with either congenital cryptorchidism or retractile testes who underwent orchiopexy from 2015 to 2019. Data collected during the study included diagnosis, surgical technique and both short- and long-term complications. Patient stratification was performed in accordance with the type of orchiopexy and the diagnosis UDT vs. RT and inguinal orchidopexy vs. scrotal orchidopexy. Results: A total of 362 children underwent 443 orchiopexies of which 227 were inguinal and 216 were scrotal. Complications were reported in 16 (3.6%) surgeries and from which 14 (3.16%) were presented in for postoperative complications. Short-term complications were presented in four (0.9%) cases and consisted of wound dehiscence. Long-term complications were recorded in 12 (2.7%) cases, including recurrence in six (1.3%) testes, testicular atrophy in three (0.6%) cases and presentation of hydrocele or inguinal hernia in two (0.4%) and one (0.2%) patient, respectively. Notably, 13 orchidopexies with preoperative diagnosis of congenital cryptorchidism, were linked with complications (p = 0.01), 12 of which underwent with two-incision technique (p = 0.07). Conclusions: The findings of the study suggest that a preoperative diagnosis of congenital cryptorchidism is a possible risk factor for postoperative complications. With regard to the surgical technique performed, the single-incision scrotal orchiopexy appears to be a much safer and more effective approach palpable undescended testes, compared to the two-incision approach. For the high-lying testes, although the single-scrotal technique provides good results, more prospective studies with selected impalpable undescended testes are needed to strengthen the existing literature.
