When faced with violet, purple or purplish-blue urine, clinicians should consider urinary tract infection in their differential diagnosis.
A 60-year-old woman with end-stage kidney disease and non-adherence to renal replacement therapy was admitted to our hospital for placement of hemodialysis catheter. During her hospitalization she had purple urine, and purple urine bag syndrome (PUBS) was diagnosed. She was effectively treated with antibiotics and her urine returned to a dark yellow color.
Although this condition is often easily treated, diagnosing PUBS in chronic renal patients probably means an increased serum concentration of indoxyl sulfate, metabolite that is involved in the progression of both CKD and cardiovascular disease.
Hence, in the context of our renal patients, perhaps PUBS is not as benign as supposed.
当面对紫色、紫红色或紫蓝色尿液时，临床医生在鉴别诊断中应考虑尿路感染。
一名60岁患有终末期肾病且未坚持肾脏替代治疗的女性因置入血液透析导管入住我院。住院期间她出现了紫色尿液，并被诊断为紫色尿袋综合征（PUBS）。她接受抗生素治疗后病情得到有效缓解，尿液恢复为深黄色。
尽管这种情况通常易于治疗，但在慢性肾病患者中诊断出PUBS可能意味着硫酸吲哚酚血清浓度升高，该代谢产物与慢性肾脏病和心血管疾病的进展均有关。
因此，在我们的肾病患者中，或许PUBS并不像认为的那么良性。
