Purple urine bag syndrome is a rare and distinctive manifestation of urinary tract infection that has been observed in patients with urethral catheterisation. The underlying mechanism of this phenomenon involves a reaction between the bacterial enzymes present in infected urine and the polyvinyl chloride components of the urine bag, leading to the manifestation of a distinctive purple colouration. The condition predominantly afflicts elderly individuals, particularly those with prolonged urethral catheterisation, and is more prevalent in the female demographic. The present case study focuses on an elderly male patient residing in a nursing home, who has a history of Alzheimer's disease and chronic kidney disease who was brought to the emergency department with complaints of oral intake disorder and constipation.
