IMPLANTAÇÃO CIRÚRGICA DE CATETER DUPLO J PARA TRATAMENTO DE URETEROLITÍASE E PIONEFROSE EM PACIENTE FELINO COM URETER CIRCUNCAVAL

Abstract

Feline ureteral obstruction is mainly caused by calcium oxalate stones. Clinical signs are considered non-specific and there are several forms of diagnosis and treatment available. In the present work, a case report was presented of a feline patient diagnosed with bilateral ureteral obstruction due to phosphate stones, with the ureterolith being removed by ureterotomy. During surgery, one of the obstructed ureters was identified as a circumcaval ureter, which may be an accidental finding when the patient has no symptoms, or when it is not diagnosed by prior imaging. The patient developed pyonephrosis as a result of ureteral obstruction, and was treated with the implantation of a double J stent. The management used to manage the patient's case showed positive results. There are several diagnostic and therapeutic alternatives for ureteral obstruction, circumcaval ureter and pyonephrosis, which may be less invasive, more effective and cause fewer complications compared to traditional approaches. The objective of this work is to carry out a brief review of the literature on ureteral obstruction in felines, as well as to report the case of a cat with a circumcaval ureter that presented a struvite ureterolith and progressed to pyonephrosis, requiring a surgical approach as a form of treatment.
