seminal vesicle cyst

Seminal vesicle cyst is a rare urological problem.[1],[2],[3] First case reported by Zinner in 1941. Seminal vesicle cysts may be congenital or acquired [1]. Present since birth, congenital cysts develop and become symptomatic in young adulthood. Accumulation of secretions in the gland owing to insufficient drainage, which is associated with atresia of the ejaculatory ducts, causes subsequent distension of the seminal vesicles, leading to formation of a cyst [6]. The cysts are usually unilateral with no predilection for side [3]. Acquired cysts are often bilateral and are seen in an older age group after a history of chronic prostatitis or prostate surgery. The seminal vesicles are paired secretory glands just posterior to the bladder. Congenital anomalies of the seminal vesicles including ectopia, hypoplasia, cyst formation and agenesis and other internal genital abnormalities are frequently associated. Most seminal vesical cysts remain asymptomatic until puberty, but with the widespread use of ultrasonography during pregnancy and infancy there are likely to be more asymptomatic cases [1, 2]. The potential complications are infection, compression of the surrounding structures [3–6], infertility and malignant degeneration. Most patients with this anomaly are asymptomatic or present during early adulthood with non-specific symptoms. Usually the cysts are 5.0 cm or less in diameter and are either a symptomatic or present during early adulthood with symptoms such as urgency, burning, hematuria and hypogastric pain mainly after coitus. Less frequently cysts larger than 8-10 cm occur and such giant cysts can result in colon or bladder obstruction with palpation of mass per rectum. Here we report a young male presenting with bilateral hydronephrosis hydroureter with acute renal failure because of giant seminal vesicle cyst causing urinary retention
