Transinguinal laparoscopy is an effective method for evaluating nonpalpable testes. This approach, performed after inguinal exploration, can avoid unnecessary procedures and offers comparable visualization to conventional laparoscopy.

Area of Science:

  • Pediatric Surgery
  • Urology

Background:

  • Approximately 20% of undescended testes are nonpalpable.
  • Conventional laparoscopy via the umbilicus is standard for nonpalpable testes.
  • Subumbilical laparoscopy may be unnecessary if the testis is below the internal inguinal ring.

Purpose of the Study:

  • To evaluate the efficacy of transinguinal laparoscopy after inguinal exploration for nonpalpable testes.

Main Methods:

  • Twelve children with 14 nonpalpable testes underwent transinguinal laparoscopy after inguinal canal exploration.
  • Laparoscopy was performed through the internal inguinal ring.

Main Results:

  • Inguinal exploration identified the testis or remnant in 5 patients, avoiding further laparoscopy.

  • Transinguinal laparoscopy visualized anatomy in 7 patients.
  • Findings included blind-ending vas deferens/spermatic vessels (4 patients) and intra-peritoneal testes (3 patients).

    • Conclusions:

    • Transinguinal laparoscopy is a viable option for managing nonpalpable testes.
    • Preceding inguinal exploration can prevent unnecessary laparoscopy.
    • Visualization with transinguinal laparoscopy is comparable to conventional methods.
