The laparoscope and the undescended testis.

Area of Science:

• Urology
• Pediatric Surgery
• Diagnostic Imaging

Background:

• Undescended testes (cryptorchidism) present diagnostic and therapeutic challenges.
• Previous methods for locating impalpable testes include venography, ultrasonography, hormone manipulation, and surgical exploration.
• Laparoscopy has emerged as a valuable diagnostic aid.

Purpose of the Study:

• To review the utility of laparoscopy in the diagnosis and management of impalpable testes.
• To evaluate the impact of laparoscopy on surgical planning for orchidopexy.
• To assess the role of laparoscopy in managing specific surgical techniques like the Fowler-Stephens procedure.

Main Methods:

• A retrospective review of 7 years of patient data was conducted.
• Laparoscopic procedures were analyzed for diagnostic accuracy and therapeutic guidance.
• Surgical approaches, including orchidopexy and Fowler-Stephens procedures, were assessed based on laparoscopic findings.

Main Results:

• Laparoscopy effectively guided the planning of orchidopexy by determining the entry point of spermatic vessels into the deep inguinal ring.
• In cases where vessels entered the deep inguinal ring, 48% of testes were found to be atrophic.
• Laparoscopy facilitated the first stage of the Fowler-Stephens long loop vas orchidopexy in three patients, with successful long-term testicular viability in two.

Conclusions:

• Laparoscopy is a valuable tool for diagnosing and managing impalpable testes.
• It aids in surgical planning for orchidopexy and identifies testicular atrophy.
• Laparoscopy is beneficial in performing staged procedures like the Fowler-Stephens orchidopexy, contributing to testicular viability.
