Abstract
Introduction

Female urethral stricture secondary to erosion by suburethral sling is an uncommon problem with a difficult solution. Ventral vaginal rotation flaps or buccal mucosa dorsal grafts are not useful because this type of stricture is very proximal (close to the bladder neck) and the vagina is thinned. We present our experience in the management this problem using excision of the involved urethral tract, associated to bladder mucosa flap and vaginal sling using transverse vaginal flap to repair the weakened vaginal wall.

Material and methods

Three females with urethral stricture secondary to urethral erosion of their sling were treated with a technique of combined urethroplasty with bladder flap and vaginal reinforcement with pediculated vaginal flap transferred as a mini-sling. Two of the patients suffered chronic urinary retention and preoperative placement of urethral catheter was not possible. The patients were evaluated 12, 36 and 55 months after surgery, respectively.

Results

Surgery was performed without complications. Results were satisfactory in all the patients, reaching good postoperative micturition caliber and without incontinence at follow-up.

Conclusion

Patients with suburethral erosion due to a synthetic sling and secondary severe urethral stricture require total extirpation of the mesh and complete reconstruction of the urethro-vaginal septum. Tension-free urethral suture and the use of vaginal sling with the technique we describe herein, are two useful technical tips for this problem.

Resumen
Introducción

La estenosis uretral femenina secundaria a erosión por cabestrillo suburetral es un problema poco frecuente y de difícil solución. Los colgajos ventrales de rotación vaginal o los injertos dorsales de mucosa bucal no son útiles, porque este tipo de estenosis es demasiado proximal (cercana al cuello vesical) y la vagina se encuentra adelgazada. Presentamos nuestra experiencia en el manejo de este problema utilizando la escisión del tracto uretral afecto, asociada a colgajo de mucosa vesical y a cabestrillo vaginal mediante colgajo vaginal trasverso para reparar la endeble pared vaginal.

Material y métodos

Tres mujeres con estenosis uretral secundaria a erosión uretral de cabestrillo fueron tratadas con una técnica combinada de plastia uretral con colgajo vesical y refuerzo vaginal mediante colgajo vaginal pediculado transferido a modo de mini-cabestrillo. Dos de las pacientes se encontraban en retención urinaria crónica, y no fue posible la colocación preoperatoria de catéter uretral. Las pacientes fueron evaluadas tras la cirugía a 12, 36 y 55 meses, respectivamente.

Resultados

La cirugía fue practicada sin complicaciones. Los resultados fueron satisfactorios en todas las pacientes, alcanzando buen calibre miccional postoperatorio y encontrándose sin incontinencia en el momento del seguimiento.

Conclusión

Los pacientes con erosión suburetral por un cabestrillo sintético y estenosis uretral secundaria severa necesitan exéresis total de la malla y reconstrucción completa del tabique uretro-vaginal. La sutura uretral sin tensión y el empleo de cabestrillo vaginal con la técnica que describimos son dos puntos técnicos de gran utilidad para este problema.
