Pseudo-acute kidney injury after minor trauma: A case report and review of literature

Diana Cheung et al. J Am Coll Emerg Physicians Open. .

Abstract

Acute kidney injury (AKI), a common diagnosis in the emergency department, is defined as a reduction in renal filtration function, with decrease in urine output, increase in serum creatinine, or both. However, a rise in serum creatinine can occur without AKI: the principal cause of a pseudo-AKI is urinary ascites, caused by urinary tract rupture, followed by reverse intraperitoneal dialysis and resorption of creatinine. The intraperitoneal leak of free urine is mainly traumatic, and half of the cases are iatrogenic. A case of intraperitoneal bladder rupture after minor trauma is presented with a review of the pathology of pseudo-AKI.

Keywords: acute kidney injury; bladder injury; emergency department; pseudo‐acute kidney injury; reverse autodialysis; urinary ascites.

Retrograde cystography. (A and B) Frontal view of retrograde cystography of a full bladder. The arrow points to the contrast leaking out of the bladder's dome. (C) Anterior view centered on the left hypochondrium. Contrast material surrounding the spleen is shown by the star. The arrow indicates contrast in the left paracolic gutter. (D) Digestive tract view. The arrow marks the contrast surrounding the bowel loops. The presence of a large amount of the contrast in the peritoneum is suggestive of intraperitoneal bladder rupture
