Purple urine bag syndrome: case report

ABSTRACT A 65-year-old male with a history of urinary tract trauma requiring cystotomy and chronic bladder catheterization, presenting with chronic and uninvestigated changes in the color of the urine bag system, with no urine color change, and positive urine culture for Proteus mirabilis . These characteristics refer to the purple urine bag syndrome, a not weel-known condition, with a benign course in most cases, and associated with urinary tract infection in patients with chronic bladder catheterization. Although it is characterized by marked changes, it is underdiagnosed by healthcare professionals.

摘要：1例65岁男性患者，有需行膀胱切开术的尿路创伤史，且长期留置膀胱导尿管。该患者因尿袋系统颜色出现慢性且未被排查的变化就诊，其尿液颜色并无异常，尿培养结果示奇异变形杆菌（Proteus mirabilis）阳性。上述特征符合紫色尿袋综合征（purple urine bag syndrome）——一种鲜为人知的病症，多数患者病程呈良性经过，且与长期留置膀胱导尿管患者的尿路感染相关。尽管该病症具有显著的临床表现，但仍常被医护人员漏诊。
