ABSTRACT


Introduction: Purple urine bag syndrome (PUBS) is a rare condition that occurs as a complication of urinary tract infections (UTI) characterized by the production of purple urine in tubes and catheter bag, related to the aberrant metabolism of tryptophan, it represents an alarming clinical condition for patients and their relatives. However prognosis is good in most of the patients but it is associated with a high mortality due to patients’ comorbidities.

Case Report: This is a 66-year-old female patient with a history of Parkinson’s disease with a history of chronic constipation and decubitus ulcers in the lumbosacral region and chronic use of a catheter bladder, secondary to the neurological pathology. She went to the emergency department with evidence of purple coloration in the urine as well as in the bag. A culture of the catheter tip showed Escherichia coli sensitive only to ertapenem, for which medical treatment was started and the urinary catheter changed, medical surveillance is continued by the outpatient clinic, reassessing the patient at 3 weeks with light yellow urinary output without stench.

Conclusion: The purple urine bag syndrome is an infrequent syndrome that requires multiple risk factors for its presentation, and despite the fact that most patients do not present any symptoms, in addition to the strange appearance of urine, it represents bacteriuria that may or may not require medical treatment based on antibiotics, but that necessarily requires the replacement of the urinary bag.
