Purple urine bag syndrome is characterized by the urinary drainage bag turning purple in patients on prolonged urinary catheterization, especially those in the bedridden state. It is associated with bacterial urinary tract infections caused by indigo-producing and indirubin-producing bacteria, usually affects women, and is associated with alkaline urine, constipation, and a high bacterial load in the urine. Almost all patients with purple urine bag syndrome are catheterized due to significant disability, and the urinary pH is 7.0 or more. In general, intensive treatment with antibiotics is not recommended. Purple urine bag syndrome per se almost always appears to be asymptomatic and harmless. However, caution is needed, because some cases have been reported to show progression to severe disease states, so further research into the morbidity and mortality of this infection is warranted.
紫色尿袋综合征的特征是长期留置导尿管的患者的尿液引流袋变成紫色，尤其是卧床患者。它与靛蓝产生菌和靛玉红产生菌引起的细菌性尿路感染有关，通常影响女性，与碱性尿液、便秘和尿液中高细菌负荷有关。几乎所有患有紫色尿袋综合征的患者都因严重残疾而接受导尿，尿液 pH 值为 7.0 或更高。一般不建议对其进行强化抗生素治疗。紫色尿袋综合征本身几乎总是表现为无症状和无害。然而，需要谨慎，因为有报道称一些病例出现病情进展为严重疾病状态，因此有必要进一步研究这种感染的发病率和死亡率。
