Abstract：
UNASSIGNED: Purple urine bag syndrome (PUBS), described first in 1978, is a rare phenomenon with purplish discolorations in the urine collecting bag. This report aims to provide a general overview of PUBS, its pathogenesis, and the recommended treatments.
METHODS: A woman patient, 27 years old, with prior history of congenital rubella infection complained of urinary retention. The patient routinely had foley catheterization due to neurogenic bladder accompanied by paraparesis inferior for 1.5 years. She also suffered bilateral lower extremities edema with infected wounds for two weeks, which showed a purple urine color in the urine bag. The laboratory examination demonstrated iron deficiency anemia, hypokalemia, and blood alkalosis.
UNASSIGNED: The cause of purplish discolorations of PUBS is the mixing of indigo, blue pigment, and indirubin, red pigment, which are results of dietary digestion, hepatic enzymes, and bacterial urine oxidation. The main risk factors are female patients, constipation, older age, recurrent UTI, renal failure, and urinary catheterization, dominantly on chronic treatment with polyvinyl chloride (PVC) urinary catheter or bag.
CONCLUSIONS: The management should be promptly, rigorously, and appropriately because the complicated UTI has a high-risk progression of urosepsis.

摘要：
未经证实：紫色尿袋综合征（PUBS），最早描述于1978年，是尿液收集袋中出现紫色变色的罕见现象。本报告旨在提供PUBS的总体概述，其发病机制,和推荐的治疗方法。
方法：一名女性患者，27岁,有先天性风疹感染史，主诉尿潴留。由于神经源性膀胱伴有下壁轻瘫，该患者常规进行foley导管检查1.5年。她还患有双侧下肢水肿，伤口感染两周，尿液袋中呈紫色尿液。实验室检查显示缺铁性贫血，低钾血症,和血碱中毒.
未经证实：PUBS的紫色变色的原因是靛蓝的混合，蓝色颜料,还有靛玉红,红色颜料,这是饮食消化的结果，肝酶，和细菌尿液氧化。主要危险因素为女性患者,便秘,年龄较大,复发性UTI,肾功能衰竭,和导尿术,主要用于聚氯乙烯（PVC）导尿管或袋的慢性治疗。
结论：管理应及时，严格,和适当的，因为复杂的UTI具有尿脓毒症的高风险进展。
