Renal Tuberculosis Presenting as Nephrocolocutaneous Fistula

Abstract

We report a very uncommon manifestation of renal tuberculosis as nephrocolocutaneous fistula (NCCF). Patient presented with chronic discharging sinus. Radiological studies of sinus tract revealed fistulous communication of tract with colon and a completely disorganized non-functional renal unit. Colonoscopy confirmed fistulous opening in descending colon. Patient was explored retroperitoneally after starting antituberculous therapy (ATT) empirically. Nephrectomy was done but colonic fistula could not be traced due to dense adhesion in colonic area. Incision was closed after putting drain. Histopathology of excised mass was suggestive of tuberculous infection. Patient got uneventful recovery with anti tuberculous chemotherapy
