Purple Urine Bag Syndrome.

Purple Urine Bag Syndrome (PUBS) refers to the purple discoloration of urine and is commonly observed in bed ridden patients with long-term urinary catheters. Although typically benign, the purple discoloration is alarming to both the patients and their attendants. This case report presents an uncommon case of PUBS in a 60-year-old lady with hypertension, type II diabetes, and chronic kidney disease stage 5, who presented to the emergency room with bilateral diabetic foot ulcers of 3 months duration, dry gangrene of ring finger and infected middle and little fingers with abscess over the palmar aspect of right hand of 20 days duration. PUBS is generally associated with alkaline urine as was observed in this patient, although it has also been reported in acidic urine. PUBS has long been documented in association with constipation and so has its association with diarrhea, a finding also observed in this case report.
