Description

Hiroaki Nishioka reports in 2026 a case of purple urine bag syndrome in a woman aged 88 years who lives in a long term care home with mild dementia. A Foley catheter was placed for urine block, and two weeks later the tube and bag turned a strong purple while the urine stayed yellow.

Germs break down a food amino acid into blue and red pigments that cling to plastic, which paints the bag in this benign state. She had no fever or mind change, so no urine test or antibiotic was given at the time. A fresh tube and bag plus bowel care cleared the colour at once. Calm spotting of the sign can spare needless drugs.
