Avaliação clínica dos gatos submetidos à técnica de uretrostomia perineal

Abstract

Perineal urethrostomy is a surgical procedure used in male cats to create a new opening between the pelvic urethra and skin in the perineal region. Indications for it include recorrent urethral obstruction and urethral obstruction that cannot be relieved by catheterization and reverse flushing. Perineal urethrostomy, when indicated and propely perfomed, is benefical to the patient and plagued with few complications. The purpose of this study was perform clinical evaluation of seventeen cats submitted to the perineal urethrostomy and evaluate the surgical complications in six months. This report evaluated the cats in the first day and up to six months after the surgery which were followed with biochemical, radiological analysis and urinalysis in this period, using questionnaires for better organization of the data. Sixteen cats had penile urethral trauma by catheterization and one cat had recurrent urethral obstruction. Complications observed after this procedure included hemorrhage, wound dehiscence, heamaturia or/and straining and urinary bacterial infection. None had urine burns or irritation or was incontinent or died. The most serious complication, urethral stricture, didn`t occur. The penile trauma was the major cause to indicate the urethrostomy. This study concluded that perineal urethrostomy predispose the urinary tract to increased bacterial contamination and subsequent infection. But many cats enjoy a long-term disease-free outcome and the clients consider their cats to have a good quality of life following surgery.
