title: Bladder neck obstruction secondary to Brunn's cyst.
abstract: A large solitary Brunn's cyst caused a ball-valve type of obstruction of the bladder neck in a 29-year-old man without endoscopic or histological evidence of bladder inflammation. Unroofing and drainage restored normal voiding. The histopathological features of Brunn's nests are reviewed.
