Spontaneous reno-jejuno-cutaneous fistula with stone: An unusual presentation of genito-urinary tuberculosis

We are reporting an unusual case of spontaneous reno-jejuno-cuteneous fistula with staghorn calculus. A 19-year-old female presented with pus discharging sinus in the left lumbar and gluteal region. Fistulography and computed tomography showed nonfunctioning kidney and fistula involving left kidney and jejunal loops. The patient was successfully treated by nephrectomy and excision of fistulous tract followed by antituberculous therapy. Histopathology revealed features of renal tuberculosis. To the best of our knowledge our case is the first case reported having reno-jejunal fistula because of tuberculosis and having cuteneous extension in the lumbar as well as gluteal region.
