[Reno-colic fistula]

Abstract

Nephro-intestinal fistulas involve the GI tract and the kidney or pyelocalyceal system. The main causes may be urologic or digestive, the site diverse. Reno-colic fistulas, although rare, are more frequently observed. We describe a case of left reno-colic fistula secondary to lithiasic pyonephrosis that presented as sepsis. Diagnosis was confirmed by retrograde pyelography. Treatment was by surgery (left nephrectomy, closure of the fistula, and colonorhaphy).
