NON-PALPABLE TESTES - ORCHIOPEXY IN SINGLE-STAGE

From 1986 to 1990, 53 non-palpable testes were treated in the department of Pediatric Surgery and Endocrinology at the Regina Marghertia Hospital, Turin, Italy. The reported patients were 45, 8 of them were bilateral with both testes non-palpable, 13 of the remaining patients were right cryptorchid and 24 were left. All patients received medical treatment, by LH-RH nasal spray and HCG, before surgery. None of the non-palpable testes descended by hormone therapy only, so that surgical exploration was always required. In the 53 reported cases, 10 gonads were not found, 13 were atrophic and 30 were abdominal. All abdominal gonads were positioned into the scrotum by orchiopexy in a single stage. Half of the patients underwent operation before the age of 2. Therefore, it is to be pointed out that the younger a patient the shorter his inguinal canal, this facilitates orchiopexy for high, undescended testes. In 10 patients a testicular biopsy was made during surgical procedure. Normal morphology and normal spermatogonia content were observed in the abdominal testes of the patients who had reached the age of 1 year. During the follow-up of the reported patients no upward displacement was observed. Eleven patients underwent postoperative testicular ultrasonography which showed that parenchymal structure of the operated testis was normal and the volume of the testis was slightly smaller than normal. Based on their experience, the authors suggest to correct cryptorchidism before the age of one year, surgical procedure follows immediatly after ineffective hormone therapy.
