Abstract
Introduction

Female urethral stenosis is not a very common pathology and its treatment is controversial. Therapeutic options vary from urethral dilatation and internal urethrotomy to other more complex reconstructive surgical techniques. The use of oral mucosa grafts to treat urethral stenosis has provided excellent long-term results in men, however there are few studies on their use in female urethral stenosis. We present our experience in the management of urethral stenosis using dorsal oral mucosa grafting.

Materials and methods

We present 2 cases of female patients with a history of repeated urinary tract infections associated with low obstructive uropathy. In both cases, we encountered distal urethral stricture and treated both with urethral plasty by means of dorsal oral mucosa grafting.

Results

The surgery took place without complications. Hospitalization time was 24hours in both cases. The catheter was removed on the tenth postoperative day. The urethrocystography showed good urethral caliber with no signs of urinary fistula. After a mean follow-up of 18 months, neither patient presented symptoms of low obstructive uropathy or urinary incontinence.

Conclusions

Urethroplasty with dorsal oral mucosa grafting is a reproducible and effective therapeutic option for the treatment of urethral stenosis in women.

Resumen
Introducción

La estenosis uretral femenina es una patología poco frecuente y con un manejo controvertido. Las opciones terapéuticas van desde dilataciones uretrales y uretrotomía interna hasta otras cirugías reconstructivas de mayor complejidad. El uso de injerto de mucosa oral para el manejo de la estenosis uretral ha demostrado excelentes resultados a largo plazo en hombres; sin embargo existen pocos estudios sobre su uso en la estenosis uretral femenina. Presentamos nuestra experiencia en el manejo de estenosis uretral utilizando un injerto dorsal de mucosa oral.

Material y métodos

Presentamos dos casos de pacientes mujeres con historia de infecciones del tracto urinario de repetición asociadas a una historia de uropatía obstructiva baja. En ambos casos se evidenció una estenosis uretral distal, siendo ambas manejadas mediante una plastia uretral utilizando un injerto dorsal de mucosa oral.

Resultados

La cirugía fue realizada sin complicaciones. El tiempo de hospitalización fue de 24horas en ambos casos. La sonda uretral fue retirada al décimo día postoperatorio. La uretrocistografía demostró un buen calibre uretral con ausencia de signos de fístula urinaria. Después de una media de seguimiento de 18 meses ambas pacientes no refieren síntomas de uropatía obstructiva baja ni incontinencia urinaria.

Conclusiones

La uretroplastia con injerto dorsal de mucosa oral es una opción terapéutica reproducible y efectiva para el manejo de la estenosis uretral en mujeres.
