Purple urine bag syndrome (PUBS) is a relatively rare phenomenon characterized by purple discoloration of the urine, catheter, and collection bag in individuals with indwelling catheters often colonized by specific bacteria. Although typically asymptomatic, it requires appropriate diagnostic evaluation and, in some cases, targeted treatment. We present a case study of an 81-year-old male with an indwelling urinary catheter who developed an uncomplicated, self-limiting case of purple urine bag syndrome. The patient exhibited the characteristic purple discoloration of the catheter tubing and collection bag, without accompanying systemic symptoms such as fever, dysuria, flank pain, or altered mental status. This case underscores the importance of recognizing PUBS as a benign condition in many instances, to avoid unnecessary diagnostic testing or antibiotic therapy, while still ensuring appropriate clinical evaluation to rule out potential underlying infections or contributing risk factors.
紫色尿袋综合征（PUBS）是一种相对罕见的现象，其特征为留置导尿管且常被特定细菌定植的个体出现尿液、导尿管及集尿袋的紫色变色。尽管通常无症状，但它需要进行适当的诊断评估，在某些情况下还需要进行针对性治疗。我们报告一例81岁男性留置导尿管患者发生的无并发症、自限性紫色尿袋综合征病例。该患者导尿管管道和集尿袋呈现特征性的紫色变色，无发热、尿痛、胁腹痛或精神状态改变等伴随全身症状。该病例强调了在许多情况下将PUBS识别为一种良性病症的重要性，以避免不必要的诊断检查或抗生素治疗，同时仍要确保进行适当的临床评估以排除潜在的潜在感染或相关危险因素。
