Bladder Mucosa Harvested with Holmium Laser for Treatment of Urethral Strictures: Does the Graft Have its Tissue Integrity Preserved?

Objective: The aim of this study is to evaluate the integrity and the microstructural characteristics of the bladder mucosa graft harvested using a minimally invasive technique with the Holmium laser (Ho-YAG) for the treatment of urethral stricture.

Materials And Methods: We studied patients with urethral strictures greater than 2 cm, with a urethroplasty indication. The patients were submitted to urethroplasty with the dorsal onlay reconstruction by a single surgeon.
