[Spontaneous renocolic fistula from lithiasic pyonephrosis (author's transl)].

A patient developed a spontaneous communication between the left kidney pelvis and the descending colon following a lithiasic pyonephrosis. Signs of sepsis were present and diagnosis was based on urological findings only. Treatment consisted of left nephrectomy combined with a colectomy and an end-to-end anastomosis of the large intestine. The published literature is reviewed.
