Abstract
|
|
|
|
Spontaneous bladder rupture is rare. Such an occurrence may appear similar to renal failure because the resulting urine leakage into the peritoneal cavity and absorption across the peritoneum increases serum creatinine although glomerular filtration rate is normal. A 46-year-old man presented with abdominal distension for 7 days after consuming a large volume of alcohol. Initial laboratory tests showed a blood urea nitrogen level of 174.3 mg/dL, serum creatinine of 11.49 mg/dL, and serum sodium of 105 mmol/L. Abdominal distension resolved after draining 5,200 mL of urine through a bladder catheter. Computed tomography cystography revealed intraperitoneal leakage of contrast dye from the left dome of the bladder, suggesting an intraperitoneal bladder rupture. Azotemia was completely normalized on the third day of hospitalization. This case shows that pseudo-renal failure should be considered when caring for a patient with unexplained azotemia and ascites.
