Purple urine bag syndrome (PUBS) is a visually striking and a rare side effect in a patient with urinary tract infection where urine in the catheter bags and tubing turn purple. The urine in PUBS gets its color from the combination of two pigments, indirubin and indigo, which are breakdown products of tryptophan. The most important risk factors include long-term catheterization, female gender, chronic constipation, old age and being bed bound. Here, we present a case of PUBS in an elderly female with a history of bladder cancer that needed catheterization along with constipation.
紫色尿袋综合征（PUBS）是尿路感染患者中一种视觉上显著且罕见的副作用，表现为导尿管袋和管道中的尿液变成紫色。PUBS中的尿液颜色来自两种色素——靛玉红和靛蓝的结合，它们是色氨酸的分解产物。最重要的危险因素包括长期导尿、女性、慢性便秘、老年和卧床不起。在此，我们报告一例患有膀胱癌病史的老年女性发生PUBS的病例，该患者需要导尿且伴有便秘。
