Purple urine bag syndrome (PUBS) is a rare disorder seen in elderly persons, wherein the urinary bag and the tubing turn in to purple colour. It is usually seen in patients who are on urinary catheters for a long time. Purple coloured urine occurs due to the accumulation of indigo and indirubin, which are the end products of tryptophan metabolism due to the action of sulfatases and phosphatases formed by bacteria like Providencia, Citrobacter, Enterobacter, Klebsiella etc. We present this interesting phenomenon of purple urine in a young male who was on prolonged urinary catheterization. The urine culture was positive for Providencia and constipation was an added risk factor for the purple urine. The urinary catheter and tubing was changed along with a course of antibiotics which lead to the normalization of the urine colour.
紫色尿袋综合征（PUBS）是一种在老年人中罕见的疾病，其中尿袋和导管会变成紫色。它通常见于长期留置导尿管的患者。紫色尿液的出现是由于吲哚和靛玉红的积累，它们是色氨酸代谢的终产物，是由普罗威登斯菌、柠檬酸杆菌、肠杆菌、克雷伯菌等细菌产生的硫酸酯酶和磷酸酶作用的结果。我们报告了一名长期留置导尿管的年轻男性出现这种有趣的紫色尿液现象。尿液培养显示普罗威登斯菌阳性，便秘是导致紫色尿液的一个额外危险因素。更换了导尿管和导管，并给予一个疗程的抗生素治疗，尿液颜色恢复正常。
