Ketamine-Induced Uropathy: A Case Report and Literature Review
Main Article Content
Abstract
Ketamine-induced uropathy caused by long-term use of ketamine leads to lower urinary tract symptoms, hydronephrosis, and recurrent urinary tract infection. The principles of treatment involve cessation of ketamine abuse, symptomatic treatments including pain control, and surgical intervention in severe cases. We report the case of a 42-year-old previously healthy male who presented with altered consciousness for 2 hours. He had frequently abused ketamine for recreational purposes over a period of two years. His laboratory results revealed acute kidney injury, uremia, metabolic acidosis, and hyperkalemia. Computed tomography revealed bilateral moderate hydronephrosis and hydroureter without any identifiable cause of obstruction, along with diffused bladder wall thickening and reduced bladder capacity, findings compatible with ketamine-induced uropathy. Continuous kidney replacement therapy was performed until his serum creatinine and electrolyte levels were normalized. He was strongly advised to discontinue ketamine use. In addition, symptomatic treatment, mainly pain controllers, was provided.
