In male cats, urinary bladder lithiasis may result in irreversible urethral obstruction. This results in bladder distention, uremia, and without proper intervention, the animal's death. In these situations, the last solution is a urethrostomy. In our study, we observed twenty cases of perineal urethrostomy and twenty cases of abdominal or prepubic urethrostomy, over a period of two years. A perineal urethrostomy is relatively easy to perform, aiming to remove the strictured part of the penile urethra, thus permitting the calculus to be passed. If the strictured prostatic urethra is not removed, in time it could become a new site for obstruction with larger diameter calculi. Although an abdominal urethrostomy is more laborious and causes more trauma, it offers long-term advantages, considerably increases lifespan, and reduces the risk of recurrence. Prostate removal, urethral shortening and vesical lavage make the removal of calculi easier. In this study, the incidence of relapse after one year was 30% after perineal urethrostomy (due to newly formed calculi or urethral strictures), and 5% in abdominal urethrostomy (due exclusively to urethrostomal strictures). In conclusion, abdominal urethrostomy offers more advantages in the postoperatively.
