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. / A uretrostomia perineal ? um procedimento cir?rgico realizado em gatos machos com o intuito de criar um novo orif?cio entre a uretra p?lvica e a pele na regi?o perineal. As indica??es dessa t?cnica incluem a obstru??o uretral recorrente e a obstru??o que n?o pode ser aliviada por cateteriza??o e lavagem reversa. A uretrostomia perineal quando indicada e realizada adequadamente, ? ben?fica para o paciente e gera poucas complica??es. O objetivo desse trabalho foi avaliar clinicamente 17 gatos submetidos ? uretrostomia perineal e as complica??es p?s-cir?rgicas no per?odo de seis meses. A an?lise foi efetuada no primeiro dia de atendimento at? o sexto m?s p?s-cir?rgico e os animais foram acompanhados com an?lises bioqu?micas, radiografias e com urin?lise, usando question?rios para melhor organiza??o dos dados. Dezesseis gatos tinham traumatismo na uretra peniana em conseq??ncia da cateteriza??o uretral e um gato apresentou obstru??o uretral recorrente. As complica??es p?s-operat?rias observadas foram hemorragia, deisc?ncia de sutura, hemat?ria/dis?ria e infec??o bacteriana urin?ria. Nenhum paciente teve irrita??o da ferida, queimadura por urina, incontin?ncia ou veio a ?bito. A complica??o mais s?ria, a estenose uretral, n?o aconteceu. A iatrogenia foi a maior causa para a indica??o da uretrostomia perineal nesses animais. Esse estudo indicou que a uretrostomia perineal predisp?e ao aumento da contamina??o bacteriana e infec??o urin?ria. Por?m muitos gatos ficam longos per?odos sem apresentar sinais cl?nicos de doen?a do trato urin?rio inferior e os propriet?rios consideram que seus gatos t?m boa qualidade de vida ap?s a cirurgia.
