Abstract
The surgical advancement of urethral reconstruction is a rapidly moving field. In the last decade, the technique for bulbar urethroplasty has evolved towards less invasive approaches with minimal transection and more tissue sparing in order to increase the patency rate. In this study, we provide a step forward in the augmented non-transected anastomotic (ANTA) urethroplasty proposed in 2012, with a true mucosa-sparing modification of the technique. In detail, the bulbar urethral lumen is approached with either a ventral or dorsal urethrotomy. Differently from previous techniques, the native urethral mucosa is neither transected nor resected but is reconstructed with a direct mucosa-to-mucosa anastomosis. This allows a complete sparing of communicant vessels that come from the corpus spongiosum to the urethral mucosa. The technique aims to preserve the native vascularity of the urethral mucosa by enlarging the native urethral plate with a direct anastomosis at the level of the stricture, and without the need for resection. In our hands the technique was easy and reproducible, and it carried promising results in the preliminary cohort where it was applied.
