Abstract

Nephro-cutaneous fistula, although reported in humans, has not been reported in the dog. In humans the majority of cases develop in patients with a history of previous renal surgery, renal trauma, renal tumours, or chronic urinary tract infection with abscess formation. The dog in this report developed a nephro-cutaneous fistula secondary to a traumatic induced renal abscess with formation of a draining sinus tract to the exterior of the body. The animal underwent simple nephrectomy, which resulted in complete resolution of the fistula.

Highlights

Nephro-cutaneous fistulas usually occur as complications of surgical procedures on the kidney, renal trauma, renal uroliths, tumours and chronic urinary tract infections with formation of peri-renal abscesses[1,3,6]
On exploratory laparotomy the right kidney was observed to be reduced to a thickened capsule containing purulent material, which was communicating with the draining sinus tract in the right body wall
Nephro-cutaneous fistula in humans is a rare condition and to the authors knowledge this is the 1st report in the dog

Summary

Introduction

Nephro-cutaneous fistulas usually occur as complications of surgical procedures on the kidney, renal trauma (penetrating or iatrogenic), renal uroliths, tumours and chronic urinary tract infections with formation of peri-renal abscesses[1,3,6]. An abscess usually develops by extension of a urinary tract infection to the adjacent tissues, either by contiguity or by lymphatic route. Abscesses can originate from an urinoma or urinary pseudocyst, which arise as result of external or surgical trauma to the kidney, promoting loss of continuity between it and the surrounding tissues[4].
