Surgery for female urethral stricture.

Background: Female urethral stricture (FUS) is a rare entity that causes great morbidity and suffering in those affected. As the available scientific data is sparce, there are no formal guidelines or standard of care for this disease.
Methods: This is a narrative review of the surgical management for female urethral stricture. The literature review was performed on PubMed. Articles were limited to English, but there was no limitation in terms of date.
Results: Management of FUS is divided between endoscopic and open surgical repair. Urethral dilation with or without urethrectomy can be offered as a first-line treatment. However, the rate of success of this procedure remains inferior to open surgical repair, and its efficacy decreases with the number of previous dilations. For distal urethral strictures, distal urethrectomy and advancement meatoplasty may be considered. Vaginal flaps are readily available, easy to harvest, well-vascularized, and allow for a dorsal or ventral orientation urethroplasty. The results of this procedure are promising, but most studies are small and retrospective. Labia flaps are easily accessible, wet, hairless, and elastic. The main limitations with the use of vaginal or labial tissues are co-existing conditions such as lichen sclerosis or vaginal atrophy, which may affect future results. Vaginal and labial graft urethroplasty can be used when it is not possible to mobilize an adequate flap. Stricture-free rates of this technique are variable. In cases of more severe stricture, an augmentation urethroplasty using buccal mucosa graft may be necessary. The techniques used in FUS replicate those for male urethral strictures, where both ventral and dorsal approaches can be utilized.
Conclusions: Although there is growing interest in the field, the optimal management of FUS remains to be determined.
