title: Epididymal abnormalities associated with undescended testis.
abstract: In a prospective study of 42 patients with undescended testes 15 (36 per cent) had epididymal abnormalities. These anomalies were divided into 3 groups, including agenesis of the epididymis, atresia of the epididymis and loop or elongated epididymis. In the second group atresia could occur at the head, body or tail of the epididymis.
