Discolouration of the urine is commonly encountered in clinical practice, ranging from brown dirty urine from urine infection to blood-stained urine from haematuria. Awareness of urine discolouration and its associations is important for diagnosis and appropriate treatment. This case report explores the rare occurrence of pink urine in a 35 -year-old obese patient following a surgery under general anaesthesia with propofol. Despite the absence of associated symptoms or abnormalities in renal function, the urine exhibited amphourous pink urate crystals, leading to discolouration. The phenomenon, known to be associated with propofol use, resolved spontaneously after four days without any complications. The case highlights the importance of recognising and understanding urine discolouration with propofol usage.
