Urinary peritonitis caused by gangrenous cystitis

We report a case of a young man who developed severe urinary sepsis, on the 21(st) day of hospitalization (DH), which was treated with ciprofloxacin and gentamicin. On the 30(th) DH, he developed bloodstream and urinary infections due to Acinetobacter baumannii which had been treated with colistin and rifampicin. On the 55(th) DH, he developed urinary peritonitis and necrosis of the anterior and posterior bladder wall. Bilateral ureterostomy was performed. The patient was treated with colistin and imipenem. Peritoneal fluid culture yielded Enterobacter cloacae susceptible to imipenem. An enterocystoplasty was performed. The outcome was favourable.
