Female urethral stricture: techniques for reconstruction

Abstract

Female urethral stricture (FUS) is a rare condition. It was not studied robustly for many years, but interest has grown recently in the reconstructive urology community, leading to an increase in publications. In this review, we gather the latest data regarding FUS and its different therapeutic options. Studies are summarized, split by technique. We also review the recently published European Guidelines. In addition, we share our preferred surgical technique and our views on future options. Diagnosing FUS can often be challenging and requires a high index of clinical suspicion. Its vague clinical symptoms and empiric initial treatments combine to make FUS an underdiagnosed condition. The lack of consensus on how to define FUS also compounds the problem. Appropriate diagnosis requires thorough investigation, and ancillary studies such as video urodynamics, cystoscopy, and voiding cystourethrogram may be useful. Treatment options range from conservative management to definitive procedures, although studies have shown that conservative measures such as urethral dilation have a low success rate overall. Within definitive management, augmented urethroplasty - using either flaps or grafts, has proven to be the gold standard. Both have shown excellent results over time; however, there is insufficient data available to recommend one over the other. Contemporary data has an overall poor level of evidence. Although challenging due to the rarity of the problem, a proper randomized controlled clinical trial comparing the principal surgical options and their outcomes would be beneficial and would allow for more informed decision making when considering options for women with urethral stricture.
