Prepucial urethrostomy, still not widespread in the literature, is based on the anastomosis of the urethra to the prepucial mucosa. The few reports of its use in the treatment of animals with lower urinary tract disease, despite the good results, present divergences in the conduction of surgical maneuvers performed to preserve the foreskin and subsequent penile anastomosis. After analyzing the reported techniques and training in cadavers to understand the surgical maneuvers and defining the surgical technique to be employed, the standardization of the technique, its feasibility and applicability in the treatment of 19 felines with lower urinary tract disease with urethral obstruction were sought, followed by a period of 180 days of postoperative observation. The operative technique was easy to perform, proving to be feasible, applicable and effective in patients who need a urethral stoma for derivation of the urinary flow. The rate of postoperativecomplications was minimal, with only one case of suture dehiscence and consequences, due to licking due to the lack of a restriction method. The analysis of the results obtained in this study allows us to conclude that the technique of urethrostomy with preputial preservation, can be considered a first choice alternative for the treatment of urethral obstruction in felines, since the stoma created forms continuously in the mucosa prepucial, minimizing the risk of complications such as stenosis, dermatitis and uremic infiltrations and ascending infections, in addition to a favorable aesthetic appearance.
