Rare congenital malformation of the seminal vesicles and homolateral upper urinary tract: the classic presentation is a seminal vesicle cyst associated with homolateral renal agenesis or hypoplasia. It results from an anomaly in the development of the mesonephric duct from which the ureteral buds and seminal glands originate, under the influence of testosterone and anti-mullerian hormone during embryogenesis. The diagnosis is usually made in the third to fourth decade of life, but can be detected earlier with the increasing use of CT and MRI scans. 

Typical symptoms include dysuria (37 %), perineal pain (29 %), epididymitis (27 %) and painful ejaculation (21 %).

Anesthetic implications:
