Update on female urethral reconstruction

Abstract

Purpose of review Female urethral stricture (FUS) is not frequent but can be the cause of significant morbidity. A somewhat overlooked condition for years, it has received significant attention in recent times. In this review, we update the current evidence surrounding FUS management. Recent findings It is estimated that FUS is present in about 1% of all women having check-ups for lower urinary tract symptoms. Etiology is considered as idiopathic in half of the cases, iatrogenic in one-third, whereas infection/inflammation and trauma account for the rest. Symptoms presented are usually nonspecific and nondiagnostic. Pelvic examination, uroflowmetry, endoscopy, and urethrography are the most frequently employed diagnostic tools. Urodynamics/video-urodynamics can be used to document obstruction and to differentiate true anatomic strictures from functional disorders. Urethral dilation (UD) is the most frequent management procedure, sometimes followed by self-dilation, but recurrence is high, at over 50%. By contrast, reconstructive surgery is far more efficient, with overall curative rates of around 90%. Summary A high index of suspicion is required to identify FUS patients. UD is advised as a first approach but after one or two failed attempts, reconstruction at a referral center should be considered.
