Abstract
Purple urine bag syndrome (PUBS) is a medical condition characterized by the appearance of purple discoloration in the urine collection bag of patients who use catheters for urinary drainage. PUBS is primarily seen in elderly, female, and institutionalized patients who have chronic indwelling catheters. The discoloration occurs due to the presence of certain bacteria that can produce indigo (which has a blue hue) and indirubin (with a red hue) leading to the formation of a purple color. PUBS may also indicate an underlying urinary tract infection or other medical conditions that require immediate attention. This case report provides an overview of PUBS, including its etiology, pathogenesis, clinical manifestations, and management. Early identification and appropriate management of PUBS can significantly improve patient outcomes, decrease healthcare costs, and enhance the overall quality of care provided to patients.
