[Female urethral diverticula--clinical and surgical aspects]

Urethral diverticula are a common cause of chronic genitourinary symptoms in women. They occur in 5% of women overall, with higher frequencies in selected populations of symptomatic women. The classical presentation is with recurrent urinary tract infections and post-micturition dribbling but almost any urinary symptom may be a presenting feature. Newer imaging modalities such as magnetic resonance imaging and perineal ultrasound are now widely available and urethral diverticula, that were previously unrecognized, can now be more easily detected. However, despite the availability of effective diagnostic techniques, diagnosis is often delayed. This is due to a lack of awareness among clinicians. These patients are often inappropriately treated for other conditions, significantly delaying the proper management of their condition. A high index of suspicion, a careful examination and referral for appropriate investigation will improve the number correctly diagnosed and lead to considerable benefit since most symptomatic cases can be cured by appropriate surgery. This review aims to summarize the presentation, investigation and management of female urethral diverticulum. Hopefully, greater awareness will lead to more timely diagnosis and appropriate treatment.
