Wereport a case of generalized peritonitis caused by spontaneous intraperitoneal rupture of the urinary bladder. A 74-year-old female was admitted with abdominal pain and biochemical findings of acute renal failure (ARF). She had recently complained of macrohematuria. She had a past history of radiotherapy for uterine cervical cancer and Parkinson's disease treated with levodopa and amantadine. Wediagnosed this case as intraperitoneal rupture of the bladder by cystogram. Biochemical findings of ARFmight have resulted from urine reabsorption. Intraperitoneal rupture of the bladder should be considered in all cases of peritonitis, especially in patients with urological symptomsand features of ARF. (Internal Medicine 35: 880-882, 1996)
