Urethral Diverticulum Defect in the periurethral fascia with an outpouching of mucosa –Infection within periurethral glands – Obstruction and abscess formation – Rupture into urethral lumen outpouchings Typically located dorsally and laterally Most common in 3 rd to 5 th decades of life
Presentation “Dysuria, Dyspareunia and Dribbling” Recurrent UTIs Urethral pain, pelvic pain, vag wall tenderness Purulent drainage per urethra Overactive bladder complaints: urgency, frequency, incontinence Romanzi et al. (J Urol, 2000): diverse presentations, mimics other disorders
Evaluation History and physical exam Careful palpation of distal anterior vaginal wall –Milk the urethra and observe meatus Cystoscopy Radiographic evaluation –Voiding cystourethrography (VCUG) –Ultrasonography (transvaginal, endourethral) –MRI ? Urodynamics - fluoro –Evaluate for stress urinary incontinence
VCUG Radiographic study of choice for years Voiding and post-void views important –Many patients cannot void on the table Blander et al. (Urology 2001): MRI and VCUG –VCUG missed 7% of diverticula and underestimated size and complexity
VCUG tic
Ultrasonography Transvaginal, endoluminal Relatively inexpensive, good visualization Operator dependant Siegel et al.: VCUG vs ultrasound. 13/15 diverticula detected with both modalities, but US showed extent and location better
Urethral diverticulum - US transurethral tic neck
CT vs MRI
Urethral diverticulum axial MRI
Urethral Diverticuli Management: –Conservative treatment measures: antibiotics, anticholinergics, anesthetics, etc.. Acutely or for very small tics –Operative Spence procedure –Very distal diverticulum Excision SUI considerations
Prepare Vaginal Wall Flap
Inicise Periurethral Fascial Tic
Prepare Periurethral Fascial Flaps Periurethral fascia flaps
Dissect Out and Excise Tic
Identify Ostium
Close Ostium
Closure of Dead Space
Periurethral Fascial Defect Closure
Close with Vaginal Wall Flap *Avoid overlapping suture lines

Management of Stress Incontinence Faerber et al: simultaneous diverticulectomy and sling, no complications, no erosions, no SUI Vasavada et al: 5 diverticulectomies, xenograft tissue for sling, no erosions, no SUI Some controversy over whether to place sling at time of diverticulectomy – if place – never use synthetic mesh
Postoperative management Urethral catheter for 14 days VCUG?? complications: –stress incontinence (de novo) –urethrovaginal fistula –recurrence –Evaluate path specimen
4/5 (80%) with Invasive adenoca had history of urinary retention
Long Term f/u of Diverticulum Recurrence N= month avg f/u 10.7% had surgery for recurrence –Risk factors Proximal diverticulum Multiple diverticula Prior vaginal or urethral surgery 26% persistent pain/discomfort with voiding 39% UTI in prior year Ingber et al, J Urol, 2011
Conclusions Diagnosis of urethral diverticula may be difficult High index of suspicion MRI is the gold standard for evaluation of suspect diverticula Surgery is the mainstay of therapy Careful exposure of all layers allows proper reconstruction Majority successfully treated
