Purple Urine Bag Syndrome (PUBS): A Rare Disease

A 68-year-old female with a known hypertensive, diabetic, and neurogenic bladder was brought to the hospital with complaints of fever and constipation. The urine bag and urine colour were found to be purple (Figure 1). The urinalysis showed alkaline urine, and the urinary sediment contained 15-20 white blood cells per high-power field. She was admitted under the impression that she had a Urinary Tract Infection (UTI) and constipation. The patient was empirically started on oral tablet nitrofurantoin. Urine cultures yielded Escherichia coli and Proteus mirabilis growth rates greater than 130/mL and 110/mL respectively.
