[Bacteremia caused by Clostridium perfringens as a complication of ureterosigmoidostomy]

A 63 year old male underwent cystectomy and ureterosigmoidostomy after diffuse carcinoma "in situ" of the bladder was discovered, and thereafter, various episodes of pyelonephritis and metabolic imbalance, in one of them, a left pneumo-ureter and a positive blood culture for Clostridium Perfringens and enterococci was detected. Empiric therapy with Aztreonam was started, and changed after to high-dose intravenous amoxicillin. Two months later the ureterosigmoidostomy was converted to an ileal conduit. The patient has remained asymptomatic on subsequent controls.
