[A case of emphysematous cystitis treated by clean intermittent catheterization : a case report].

Emphysematous cystitis is a rare condition characterized by air formation in and around the bladder wall by gas-forming organisms. An 89-year-old non-diabetic man with benign prostatic hyperplasia and neurogenic bladder presented at our hospital with fever and lower abdominal pain. Urinalysis and urine culture revealed pyuria and bacteriuria with Citrobacter freundii. Abdominal computed tomography revealed intramural gas, which suggested the diagnosis of emphysematous cystitis. He recovered and the intramural gas appeared to have disappeared on the abdominal computed tomography after urinary drainage and antibiotic therapy. Ninty-nine cases of emphysematous cystitis have been reported in Japan including this case.
