A change in the colour of urine is always of clinical significance, and a source of concern for the patient and his physician. Among the different urine colours observed, purple is the least common. Although purple discolouration of a catheter and a urine bag is an uncommon finding, it was reported in the literature as early as 1978, by Barlow and Dickson. We present a unique case of purple urine bag syndrome in a patient with bilateral nephrostomy tubes (NT) and associated urine bags (UB) with only the left nephrostomy tube and urine bag exhibiting the purple colour, which resolved with a course of appropriate antibiotics eradicating the causative bacterial pathogen, and change of NT and UB.
尿液颜色的改变总是具有临床意义，也是患者及其医生所关注的问题。在观察到的不同尿液颜色中，紫色是最不常见的。尽管导尿管和尿袋出现紫色变色是一种罕见的发现，但早在1978年，Barlow和Dickson就在文献中对此进行了报道。我们报告了一例独特的紫色尿袋综合征病例，该患者双侧置有肾造瘘管（NT）及相关尿袋（UB），仅左侧肾造瘘管和尿袋呈现紫色，通过使用适当的抗生素疗程根除致病细菌病原体以及更换NT和UB后，紫色消失。
