Primary spontaneous renocutaneous fistula

Spontaneous renal fistula to the skin is rare. The majority of cases develop in patients with antecedents of previous renal surgery, renal trauma, renal tumors, and chronic urinary tract infection with abscess formation.We report the case of a 62-year old woman, who complained of urine leakage through the skin in the lumbar region for 2 years. She underwent a fistulography that revealed drainage of contrast agent to the collecting system and images suggesting renal lithiasis on this side. The patient underwent simple nephrectomy on this side and evolved without intercurrences in the post-operative period.Currently, the occurrence of spontaneous renal and perirenal abscesses is extremely rare, except in patients with diabetes, neoplasias and immunodepression in general.

“…Spontaneous renal fistula to adjacent organs is not an uncommon phenomenon, however the spontaneous communication between kidney and skin is rare and few cases are described in the literature (1)(2)(3). The occurrence of spontaneous fistulas in patients without surgical history is rare (3).…”

“…However, the spontaneous communication between kidney and skin is rare and few cases are described in the literature 2,3,4,5 . The majority of cases reported in the medical literature are associated with chronic urinary tract infection secondary to renal stones 2,3,4,5 .

“…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 . Perirenal abscesses can develop either from organs adjacent to the kidney or from the kidney itself.…”

Nephro-cutaneous fistula, although reported in humans, has not been reported in the dog. Inhumansthe 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.

“…In humans, fistulas can develop between the kidney and several other organs (pleural cavity, lungs, bronchia, bowel, skin;Bryniak 1983). The majority of cases were reported in patients with a history of previous renal surgery, renal trauma, renal tumours, or chronic urinary tract infection with renal abscess formation (Ansari et al 2004).…”

This report describes the case of spontaneous nephro-cutaneous fistula with pyonephrosis due to renal calculi and obstructive nephropathy without renal surgery or trauma history in two dogs. A five-year-old, female, Shih-tzu and a seven-year-old, female, Maltese were presented with erythematous swelling, and subcutaneous abscess formation in their flanks. Complementary exams were performed and ultrasonography revealed marked enlargement of the kidneys with hyperechoic purulent debris filling, subcutaneous abscesses and the formation of draining sinus tracts between renal abscesses and subcutaneous tissue. At surgery, kidneys were grossly dilated and contained purulent material, which was visible in the draining sinus tract in the abdominal wall. Thus, a nephrectomy was performed. The dogs recovered uneventfully and three months later there were no further specific problems.
