[Reno-colonic and reno-cutaneous fistula in calculous pyonephrosis. Apropos of a case].

The authors present a case of reno-colonic and renocutaneous fistula in a patient with calculous pyonephrosis. The diagnosis was established by retrograde pyelography as the IVP showed no contrast excretion by the right kidney. Surgical treatment consisted of nephrectomy, colonic fistula excision and suture of the colonic wall without a diversion operation.
