Seminal Vesicle Cysts

Seminal vesicle cysts are either congenital or acquired and usually develop on basis of a ejaculatory duct obstruction. Another cause for cysts of the seminal vesicles is the autosomal dominant polycystic kidney disease (ADPKD). Most important differential diagnosis is an ectopic ureter ending in the seminal vesicle. Imaging is best done with MRI (Arora, 2007).

Treatment is necessary only in case of symptoms or infection. Percutaneous perineal cyst drainage is possible. If this fails, an open or laparoscopic surgical removal of seminal vesicle should be done. In case of an ectopic ureter, open or laparoscopic nephroureterectomy with removal of seminal vesicles is the most common treatment alternative, since renal function is often absent.
