Long-Term Outcome of Scrotal Incision Orchiopexy for Undescended Testis

Abstract

To perform a prospective study to evaluate the success of scrotal incision orchiopexy in children with a palpable undescended testis within the inguinal canal or beyond the external inguinal ring with or without inguinal hernia. A total 204 scrotal orchiopexies were performed in 166 patients with a primary undescended testis. These children were followed up for an average of 29.4 months to document the testicular position and size. The scrotal orchiopexy technique was successful in 192 testes; the remaining 12 testes required conversion to traditional inguinal orchiopexy because of inadequate mobilization. Of 108 children (128 testes) in whom the testis was distal to the external inguinal ring, this technique was successful in 104 (124 testes). The success rate was 96.9% (124 testes of 128), and only 4 patients (four testes) required conversion to a traditional inguinal incision. The average operative time was 15 minutes in this group. In the other group with 58 children (76 testes) with a testicular location within the inguinal canal, conversion to the traditional inguinal orchiopexy was performed in 8 patients (eight testes). The success rate in this group was 89.5% (68 of 76 testes). The average operative time was 21 minutes in these patients, and follow-up ranged from 16 to 68 months (average 29.4). All testes were satisfactorily positioned in the scrotum, and no testicular atrophy developed. The results of our study have shown that scrotal orchiopexy is simple, safe, and effective in selected cases compared with the standard two-incision approach in the treatment of the palpable undescended testis.
