Abstract:
Purple urine bag syndrome (PUBs) is a rare and startling phenomenon of purple discolouration
in the urine or urinary catheter and bag. It is reported in chronically debilitated elderly patients,
mostly in women on long-term urinary catheters. Its prevalence is strikingly more common in
nursing home residents. Several factors contribute to the formation of indigo (blue) and indirubin
(red) pigments from a breakdown of dietary tryptophan, which stains the urine purple. These
factors include constipation, dysmotility of the bowel, bowel bacterial overgrowth, dehydration, and
urinary tract infection. The presence of purple urine may cause undue alarm to both the patient and
the doctor. Thus, we present this case report on an 86-year-old woman, a nursing home resident
on a long-term urinary catheter, who presented to the primary care clinic. Her urine cleared
after antibiotic therapy, replacement of her urinary catheter, and supportive management, which
included hydration and nutrition. In addition to these measures, reducing the time between urinary
catheter changes was recommended to prevent recurrence of this condition.
