Diagnosis of female diverticula using magnetic resonance imaging.
We investigate the ability of physical exam to diagnose urethral diverticula with or without magnetic resonance imaging (MRI) and exclusive of invasive modalities. A retrospective chart review of all women undergoing urethral diverticulectomy at our institution since 1999 was performed. We identified 28 female patients with a mean age at diagnosis of 42.6 years (range 18-66). Common presenting symptoms included dyspareunia, urgency, and frequency. Physical exam revealed a suspected urethral diverticulum in 26 (92.9%) patients, which was confirmed postoperatively in 17 of the 20 (85%) women who underwent surgical resection. Noninvasive imaging modalities (MRI or CT) were available for review in 20 (71%) cases and made the correct diagnosis of urethral diverticulum (presence or absence) in 19 (95%) patients. In those patients with symptoms of stress or urge incontinence (11, 39%), voiding cystourethrogram (VCUG) was performed. Urethral diverticula are often easily diagnosed on physical exam. MRI can be a useful adjunct for defining diverticular extent in surgical planning, especially for proximal and complex diverticula, and should be the modality of choice if clinical suspicion is high based on patient symptoms and physical exam.
