Uretroplastia de sustitución con doble injerto de mucosa oral como opción terapéutica para pacientes con estenosis de uretra bulbar asociada a UroLume®

Abstract

UroLume^®, or urethral endoprosthesis, was conceived as an easy placement device for patients with recurrent bulbar urethral stricture. With the passage of time, it was shown to cause more complications than benefits and its use was discontinued. However, it created a group of patients with complex urethral stricture that required multiple surgical treatments with unsatisfactory results. The widespread use at the end of the 1990s of buccal mucosa grafts for the treatment of urethral stricture began a new stage in the search for a definitive treatment for this type of patient.

The aim of our article was to present a surgical technique for the treatment of UroLume^®-associated bulbar urethral stricture that has not been described in the literature.

A 71-year-old man presented with bulbar urethral stricture secondary to transurethral resection of the prostate who, 8 years ago, had UroLume® placement. He presented with another urethral stricture and was treated with numerous urethral dilations. Through the perineal approach, the endoprosthesis was completely removed, and based on the local tissue characteristics, a dorsal inlay and ventral onlay double buccal mucosa graft was placed with successful results at the 6th month of follow-up.
