[A case of fistula of small intestine and ileal conduit urinary diversion improved by conservative therapy].

A 71-year-old male was admitted for bladder cancer, and we performed a radical cystectomy and urinary diversion by means of an ileal conduit. Twenty days postoperatively, we identified the presence of stool in the stoma and noted the existence of a fistula of the small intestine and ileal conduit urinary diversion. Treatment with fasting, intravenous hyperalimentation and intravenous drip administration of octreotide acetate were performed. The fistula was closed completely 47 days after the surgery. The early complications of urinary diversion by means of an ileal conduit were reported to be urinary tract infections, bowel obstruction, and delayed wound healing, but a fistula between the small intestine and ileal conduit is very rare. We herein report a case of a fistula between the small intestine and ileal conduit used for urinary diversion which thereafter healed by conservative treatment.
