title: Malformation of the epididymis in undescended testis.
abstract: During a 6-year period, 312 boys (mean age 4.7 years) underwent orchidopexy for cryptorchidism. A total of 388 epididymides were examined and the configurations were recorded as a prospective trial. This study consists of 166 ectopic testes and 222 undescended testes. The observed configurations of epididymides in the ectopic testes were: type 1a in 99 cases (59.6%), type 1b in 35 (21.1%), type 2 in 24 (14.5%), type 3 in 7 (4.2%), and type 4 in 1 (0.6%). There were no patients in the study with type 5 and 6 anomalies. The configurations of epididymides in the undescended testes were: type 1a in 105 (47.3%), type 1b in 63 (28.4%), type 2 in 26 (11.7%), type 3 in 13 (5.9%), type 4 in 5 (2.3%), type 5 in 7 (3.2%), and type 6 in 3 (1.4%). The data revealed that the incidence of epididymal abnormalities in undescended testes (41%) was higher than that in the ectopic testes (25.9%) (P < 0.05).
