Urethral Diverticulum

Urethral diverticula are protrusions of the urethra into the periurethral fascia. Urethral diverticula are thought to result most commonly from rupture of chronically infected and obstructed periurethral glands into the urethral lumen. Clinically, urethral diverticula classically manifest as dysuria, dyspareunia, and post void dribbling, although most patients present with nonspecific signs and symptoms. Physical examination often does not help narrow the diagnosis, since urethral diverticula may not be palpable or tender, and may mimic more diffuse lesions, or vaginal wall lesions. MR imaging allows high-resolution imaging of the female urethra and periurethral region.
