Abstract
Ventral and dorsal midline wide-mouthed diverticula and Cowper's perforate syringoceles were diagnosed in 12 men with symptoms such as post-voiding dribbling, dysuria, urethral discomfort and haematuria. In all cases the diagnosis was made during urethroscopy and most patients were treated at the same time with transurethral incision of the diverticular wall, thereby marsupializing the diverticulum into the urethra. Diverticula of the male anterior urethra are more common than has been hitherto assumed. In patients with longstanding and/or recurring urethral symptoms and post-voiding dribbling urethroscopy should be included in the Investigation.
