[A case of ectopic vas deferens with a chief complaint of male sterility]

Abstract

A case of ectopic vas deferens in a 40-year-old male was reported. He visited our clinic with a complaint of male sterility for the past 10 years. Urological examinations revealed azoospermia, right renal aplasia and the ectopic insertion of right vas deferens into the right lower ureter with a blind-ending ureterocele. Bilateral testicular histological studies showed normal spermatogenesis in right testis and no spermatogenesis in left one. A vasovasostomy was performed. Sperm were seen in the semen 3 weeks after the operation. Including this patient, 54 cases (74 ectopic vas deferens) have been reported in the literature to date. The characteristics of age, subjective complaints, accompanied anomalies, diagnosis, treatment and the embryology are discussed.
