Early Experience with Laparoscopic Management of Nonpalpable Undescended Testes.

Background: Nonpalpable undescended testes (NPT) constitute 20%-30% of undescended testes, and its management has been a challenge both in diagnosis and treatment. Worldwide, laparoscopy is the current gold standard of management. In Nigeria, the management of NPT has largely been by open surgery with consequent high morbidity. In Nigeria, the trend is changing from a largely open management with its attendant high morbidity, to laparoscopic management which is the current worldwide gold standard of care.

Aim: This study aims to classify the laparoscopic features of NPT and determine the outcome of managed cases in our center.

Methodology: Prospective data were collected from consecutive patients who had laparoscopy for NPT at the Paediatric Surgical Unit of Nnamdi Azikiwe University Teaching Hospital, Nnewi, Nigeria from June 2014 to July 2016.

Results: A total of 15 patients with 23 testes were treated. There were eight patients with bilateral NPT; four had left and the remaining three right NPT. The age ranged from 1.2 to 29 years with a median of 5 years. Eleven out of the 22 internal inguinal rings were open. The position of the testes was canalicular (2), peeping (2), low abdominal (6), high abdominal (6), blind-ended vas (1), absent vas and vessels (5). No further intervention was needed for the six agenetic/atrophic testes. Standard open orchiopexy was done for the two canalicular testes. Eight testes were brought down by one stage laparoscopic orchiopexy while four were brought down by staged laparoscopic Fowler-Stephens procedure. Laparoscopic orchiectomy was done in two patients (a grossly dysmorphic testes [nubbin] and a high abdominal testis in a 29-year-old). Orchiopexy was successful in 11 out of 15 fixed testes. Of the unsuccessful ones, three testes were atrophic (volume less than what it was initially) while two were high scrotal (one testes has both complications). There was no conversion to open abdominal surgery. All patients were discharged within 24 h of surgery.

Conclusion: Laparoscopy provides for a better management of NPT by combining diagnosis and intervention in the same sitting with a good success rate and minimal postoperative morbidity.
