Case report details purple urine bag syndrome in a 49-year-old oncology patient with urinary tract infection, suggesting unique bacterial interactions.
Purple bag syndrome is a rare manifestation of urine discoloration associated primarily with chemical reactions caused by the indoxyl sulfatase/phosphatase activity of some bacteria or as secondary metabolites of food or supplement intake, whether oral or parenteral. Its presence causes confusion, leading to unnecessary laboratory tests and treatments. Is reported the clinical case of a 49-year-old oncology patient admitted to the trauma service for a pathological fracture and urinary tract infection. She was fitted with a urinary catheter, which contained purple urine. Laboratory tests were requested to identify the causative bacteria. The catheter was replaced, and antibiotic treatment was started, leading to resolution of the clinical picture.
