Male genital malformations associated with right renal agenesis.

A 30-year-old man visited our department complaining of discomfort on micturition. Hypoplasia of the bilateral epididymis, impalpable vas deferens, and prostatic tenderness were noted. Diagnostic imaging revealed agenesis of the right kidney, cystic dilation of the right seminal vesicle, and a prostatic utricle cyst. Examination of the genital tract confirmed aplasia of the left seminal vesicle and vas deferens and hypoplasia of the right seminal vesicle. On the basis of postoperative extravasation of contrast medium to the right epididymis, cystic dilation of the right seminal vesicle was diagnosed.
