A Case Of Acute Kidney Injury In A Patient With Renal Hypouricemia Without Intense Exercise

Exercise-induced acute kidney injury (EIAKI) frequently develops in patients with renal hypouricemia (RHUC). However, several cases of RHUC with acute kidney injury (AKI) but without intense exercise have been reported. We encountered a 15-year-old male with RHUC who experienced AKI. He reported no episodes of intense exercise and displayed no other representative risk factors of EIAKI, although a vasopressor had been administered for orthostatic dysregulation before AKI onset. His kidney dysfunction improved with discontinuation of the vasopressor and conservative treatment. Thus, AKI can develop in patients with RHUC in the absence of intense exercise, for which vasopressors may be a risk factor.
