We report the cases of two patients presenting with emphysematous cystitis. The first patient was a man in his 80s who was undergoing maintenance dialysis at our hospital. Hematuria and lower abdominal pain developed during hospitalization for detailed treatment of hypoxemia. Ultrasonography showed thickening of the bladder wall and a gas appearing as a shadow in the posterior bladder lumen, suggesting emphysematous cystitis. The second patient was a woman in her 80s. Hematuria and lower abdominal pain developed during hospitalization for the treatment of pneumonia. Ultrasonography showed gas appearing as small echogenic foci located within the bladder wall and a gas appearing as a shadow in the posterior bladder lumen, so emphysematous cystitis was suspected. Similar findings were found in subsequent CT examinations in both patients. Escherichia coli was isolated in both patients by urine culture, and the result of a drug susceptibility test revealed that it was an ESBL-producing strain. They were treated by bladder drainage and appropriate antimicrobial therapy.
