[Abdominal pain and ascites formation in a 72-year-old woman].

A 72-year-old woman presented with abdominal pain after micturition. Abdominal ultrasound screening revealed ascites associated with acute renal failure. Paracentesis of the peritoneal fluid was performed. Biochemical analysis indicated a peritoneal transsudate and increased creatinine. Cystoscopy detected a rupture of the urinary bladder. Catheterization and antibiotic therapy resulted in an improvement of pain and closure of the hole in the urinary bladder wall. Several different disorders can induce a rupture of the urinary bladder. In this case, severe chronic constipation was the most probable causative disease.
