title: Intraperitoneal rupture of the bladder causing the biochemical features of renal failure.
abstract: A group of 20 patients with intraperitoneal rupture of the bladder was compared with a group of 20 patients with haematuria due to renal injury. In patients admitted to hospital within 24 h of sustaining an intraperitoneal bladder rupture, the mean serum levels of creatinine and potassium were increased and the mean serum sodium level was decreased. However, the individual serum creatinine values were within normal limits in six of the 11 patients in this group. Patients presenting more than 24 h after intraperitoneal bladder rupture had an increased mean serum urea, creatinine and potassium level and a decreased mean serum sodium and CO2 content. The individual serum urea and creatinine values on admission to hospital were higher than normal in all nine patients in this group but the serum urea/creatinine ratio was not significantly elevated. A dramatic decrease in serum urea and creatinine levels was seen within 24 h after laparotomy and suturing of the bladder rupture. In patients with abdominal symptoms and signs, haematuria and the biochemical features of renal failure (elevated serum urea, creatinine and potassium, decreased serum sodium and CO2 content), the clinician should suspect an intraperitoneal rupture of the bladder.
