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

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.
