ABSTRACT=Nephrocutaneous fistula (NCF) is a rare and severe complication of renal disease and surgical procedures. Treatments for NCF were based on the renal function, and can include nephrectomy, heminephrectomy, nephroureterectomy, endourological maneuvers or antibiotic therapy alone. We reported a case of a chronic NCF which occurred 5 years after partial nephrectomy. Here we describe a new surgical approach for the management of a patient with postoperative NCF. In the present case, in addition to completely removing the fistulous tract, we also performed an omental flap grafting to tightly covered the kidney. In addition to limiting and controlling the local inflammation, the omental flap prevents contact between the kidney and the flank muscle on its posterior rim. No recurrence or complications occurred after 10 months follow-up. The NCF was successfully treated with completely removal of the sinus tract and omental flap grafting, and without nephrectomy. This case adds new aspects to the treatment of NCF.
