[Intraperitoneal Spontaneous Rupture of the Bladder Subsequent to Irradiation of the Uterus: a Case Report]

We report a case of spontaneous intraperitoneal rupture of the bladder. A 54-year-old woman was admitted to our hospital with the chief complaints of severe lower abdominal pain, dysuria and macroscopic hematuria in October, 1985. In 1969, she had had a radical hysterectomy and postoperative irradiation for cancer of the uterus. Two years later she had undergone additional irradiation. On physical examination, the abdomen was tender with guarding and signs of peritonitis. Laboratory data revealed a blood urea nitrogen of 32.8 mg/dl and all electrolytes were normal. Excretory urogram showed normal upper urinary tract but irregularity of the bladder dome. Cystoscopy revealed acute inflammation of the bladder mucosa. Consequently, we made a presumptive diagnosis of radiation cystitis and she was treated with antibiotics and drip infusion. Within a week her general condition was improved and she had discharged. In June, 1986 she was admitted again with the same chief complaints as at her first admission. Cystoscopic findings showed a hole on the postero-superior wall and retrograde cystogram revealed an intraperitoneal rupture of the bladder. At exploration a necrotic bladder wall was resected and closed in 3 layers. The post operative course was uneventful.
