We report a case of a cutaneous renocolic fistula in a patient with staghorn calculus and diverticulitis. The most common origins of renocolic fistula are primary renal diseases including xanthogranulomatous pyelonephritis, trauma, malignancy or tuberculosis. While diverticulitis has rarely been associated with renocolic fistula, previous instances of fistulae have been ...
