What is a urethral diverticulum?
A urethral diverticulum is often seen in women who present with a history of postvoid dribbling, dyspareunia, or a fluctuant mass on the anterior vaginal wall. The diverticulum results from infection in periurethral glands, which rupture into the periurethral soft tissues but continue to communicate with the urethra. Urethral diverticula can serve as a source of recurrent UTIs. Stones can form in urethral diverticula, and malignancy can also develop in the diverticula. Treatment is surgical resection; removal of the neck that connects the diverticulum to the urethra is important to prevent recurrence.
