[Spontaneous nephro-cutaneous fistula]. / Fistola nefro-cutanea spontanea.

ABSTRACT

The authors report a rare case of spontaneous nephrocutaneous fistula. The patient was asymptomatic and with a negative history for renal lithiasis, inflammation, trauma or tuberculosis. Radiological and echographical examinations permitted a complete study of the fistulous tract and the renal function; the staghorn calculi and pyelonephritis guided the decision to operate on the patient performing a nephrectomy and ureterectomy with a quick complete recovery. Biological test for micobacterium tuberculosis resulted positive after 60 days.
