Abstract

Reconstruction of the rat urethra using the CO2 laser and a protein solder has dramatically decreased the postoperative fistula rate and decreased surgical time over conventional microsurgical reconstruction. Using the rat as a model, a partial transection of the ventral urethra was repaired in one of three ways in 39 animals: conventional microsuture repair, laser assisted microsuture repair and laser assisted microsuture repair with a protein solder. The success rate in each group was 50%, 58% and 90% respectively. Therefore, the laser repair is as efficacious as conventional microsuture repair. More importantly, laser with solder is significantly better than either the conventional method or laser alone.
