A obstrução ureteral por nefrolitíase ocorre ocasionalmente no gato e parece ter incidência crescente na população felina. O seu diagnóstico é feito com base nos sinais clínicos, análises bioquímicas, com destaque para a medição de ureia e creatinina, e recorrendo a meios complementares de diagnóstico como a radiografia e a ecografia. Para o seu tratamento, pode-se recorrer numa primeira abordagem a uma terapêutica médica, no entanto, esta é muitas vezes ineficaz, pelo que geralmente há necessidade de intervir cirurgicamente. Tradicionalmente a nefrolitíase tem sido resolvida através de técnicas com elevado grau de complicações, tais como a ureteronefrectomia, nefrotomia, pielolitotomia, ureterotomia, ureteroneocistostomia e o transplante renal. Contudo, técnicas inovadoras e menos invasivas têm surgido. Entre elas, está o bypass ureteral subcutâneo, uma técnica recentemente introduzida em Portugal. Este trabalho visa a descrição detalhada desta técnica no gato em 35 intervenções abordadas no Hospital Veterinário do Restelo. Foram calculadas as taxas de mortalidade e de complicações observadas e descritas as principais complicações associadas, assim como as medidas de correção implementadas.
ABSTRACT - Subcutaneous Ureteral Bypass: retrospective study - Ureteral obstruction due to nephrolithiasis occasionally is a common disease of domestic cat and seems to be increasing in the feline population. Diagnosis is based on clinical signs, blood work, especially for urea and creatinine, and using complementary diagnostic tests such as X-ray and ultrasound. For treatment, one may start with medical treatment, however, this is often ineffective. Therefore there is usually the need for surgical intervention. Nephrolithiasis has been traditionally resolved by techniques involving high complication rates, such as ureteronephrectomy, nephrostomy, pyelolithotomy, ureterotomy, ureteroneocystostomy and kidney transplantation. However, innovative and less invasive techniques have emerged. These include the subcutaneous ureteral bypass, a recently introduced technique in Portugal. This study aims to describe in detail the use of this technique in cats including 35 interventions addressed at the Hospital Veterinário do Restelo. The mortality and complications rates observed were calculated and the main complications associated were described, as well as the corrective measures implemented.
