An interesting observation: prolonged green urine can be a combined effect of decreased liver and renal function in a patient with heart failure-a case report.

Our case report sheds light on the complex interaction between drug metabolic pathways and their potential for prolonged side effects, particularly in patients with multiorgan dysfunction. The association between propofol, MB, and green urine discoloration in the context of HF warrants further investigation, emphasizing the need for increased awareness of drug interactions and their implications in complex clinical scenarios.
