Orchidopexy: a 10-year Clinical Experience

Yoon, Jae Sik; Kim, Kwang Sae

Abstract

We analyzed our experience of orchidopexies performed during last 10 years to evaluate results and to determine the possible approach to the treatment of undescended testes. Between 1988 and 1997, we had treated 420 undescended testes (314 palpable and 106 nonpalpable) in 356 boys. Average patient age at presentation was 4.1 years with 40.2% presenting before the age of 2 years. Of 106 nonpalpable testes, 23 testes were intraabdominal, 32 were preperitoneal and 51 were absent at the surgery. During the period of first 5 years, we had performed the surgery through 31 inguinal and 13 midline transabdominal incisions for 44 patients nonpalpable testes, while during the later 5 years, all 47 patients nonpalpable were treated through inguinal incisions. For the nonpalpable testes, the inguinal approach with or without intraperitoneal extension was successful in defining the location of testes and blind-ending vessels in all patients. Laparoscopy was not helpful in avoiding surgical exploration in all our patients with nonpalpable testes. Of 339 inguinal and midline transabdominal orchidopexies without spermatic vessels ligations, 324 testes were placed in the scrotum, 4 in the upper scrotum and 3 in the inguinal area. Eight were resulted in atrophy. Of 13 Fowler-Stephens orchidopexies, 7 were placed in the scrotum and 6 were resulted in atrophy. Testicular growths were noticed in most patients who underwent orchidopexies and the volume of fixed testes became as large as the contralateral normal testes by the mean duration of 43.3 months postoperatively. In conclusion, orchidopexies were successful in most cases of cryptorchidism in terms of testicular position and growth. However, there were more testicular atrophies in patient in whom spermatic vessels were ligated. In cases of nonpalpable undescended testis, the inguinal approach with or without intraperitoneal extension would be recommended.
