Germ cell tumors of the testis following orchiopexy

Out of 335 patients with testicular neoplasms, cryptorchidism was concomitant in 84 cases (25%). 28 patients underwent orchiopexy at the age of 5-52 years. Tumor was detected, on the average, 14,4 years after the operation. Orchiopexy contributes to carcinogenesis in the undescended testicle. The rate of incidence of non-seminomatous tumor is relatively higher in patients after orchiopexy than in untreated cases of cryptorchidism. Patients with undescended testicle should be referred to a group at high risk and be followed up.
