Purple urine bag syndrome is an unusual condition that heralds an underlying urinary tract infection, in which certain bacteria produce a purple discolouration within the catheter bag of affected cases. It is most often seen in elderly women with constipation. While alarming, it can be resolved by treating the infection causing it. This report presents an elderly patient who developed the condition while an inpatient, and discusses the pathogenesis behind the condition.
