Divertículo uretral femenino. a propósito de un caso

Abstract

PurposeWe describe the successful repair of a large and complex urethral diverticulum in a female by transvaginal approach. Epidemiology, diagnostic methods, treatments and complications of female urethral diverticula are reviewed. Patients and methodsA 35-year-old woman with a history of postvoid dribbling, dyspareunia and recurrent urinary tract infections for 4 months was refered. Magnetic resonance imaging demonstrated two fluido-filled collections in the pelvis of 3.5 and 1 cm in size respectively which may be a very large and complex diverticulum, however, Bartholin gland cyst could not be rule out. Cystourethroscopy revealed a urethral diverticulum at 10 mm from the bladder neck with two ostia. It was performed transvaginal diverticulectomy and an anterior vaginal wall flap was placed. The published literature on female urethral diverticula was identified using a Pubmed Medline search and analysed. ResultsConvalescence was unremarkable. Suprapubic cystostomy tube was removed 2 weeks after surgery. The patient regained normal voiding. In the published literature there are no agreement neither in the diagnostic nor in the surgical techniques for female urethral diverticula. ConclusionsUrethral diverticula are diagnosed with increasing frequency. However, this entity continues to be overlooked because the symptoms may mimic other disorders. Cystourethroscopy, retrograde urethrograme using a double balloon catheter and recently magnetic resonance imaging may diagnose this disease. The cure rate of urethral diverticula with appropriate surgical management has a range of 86-100%. Complete excision through the anterior vaginal wall is the most successful treatment modality with minimun postoperative complications.
