INTRODUCTION: When faced with violet, purple or purplish-blue urine, clinicians should consider urinary tract infection in their differential diagnosis. CASE REPORT: A 60-year-old woman with end-stage kidney disease and non-adherence to renal replacement therapy was admitted to our hospital for placement of hemodialysis catheter. During her hospitalization she had purple urine, and purple urine bag syndrome (PUBS) was diagnosed. She was effectively treated with antibiotics and her urine returned to a dark yellow color...

Purple urine bag syndrome (PUBS) is a rare condition in which there is purple discoloration of the urine with its collecting bag and associated tubing occurs. It is considered a benign condition. We report an unusual case of PUBS in an 87-year-old female from nursing home who had a history of recurrent UTI. She also had a history of ureteral obstruction requiring left nephrostomy tube. She was brought to emergency department with altered mental status which developed five days after the occurrence of purple discoloration of the urinary bag...

Purple urine bag syndrome is characterized by the urinary drainage bag turning purple in patients on prolonged urinary catheterization, especially those in the bedridden state. It is associated with bacterial urinary tract infections caused by indigo-producing and indirubin-producing bacteria, usually affects women, and is associated with alkaline urine, constipation, and a high bacterial load in the urine. Almost all patients with purple urine bag syndrome are catheterized due to significant disability, and the urinary pH is 7...

Purple urine bag syndrome (PUBS) is a unique disease entity characterized by an alarming purple discoloration of the urine secondary to recurrent urinary tract infections with indigo- and indirubin-producing bacteria. It is usually associated with prolonged urinary catheterization and chronic debilitated states. We hereby present a concise review of this rare phenomenon with historic perspectives, epidemiology, emphasizing on current concepts of etiology, pathogenesis, relevant clinical associations, treatment modalities, prognosis, and future directions in PUBS...

Purple discoloration of a urinary catheter bag is very rare. This phenomenon is known as the purple urine bag syndrome. It is associated with urinary tract infections occurring in catheterized patients, generally elderly females with significant co-morbidities and constipation. The urine is usually alkaline. We present a unique case of this rare and interesting phenomenon occurring in acidic urine and discuss the pathophysiology.

Purple urine bag syndrome (PUBS) is an uncommon disorder, in which the plastic disposable urinary catheter bag turns purple or blue following hours or days of urinary catheterization. The purple discoloration results from indirubin dissolved in the plastic mixing with indigo in the urine. Bacteria possessing indoxyl sulfatase degrade indoxyl sulfate into indirubin and indigo. Indoxyl sulfate is derived from the metabolism of tryptophan. PUBS usually occurs in chronic catheterized elderly women who are constipated and poorly ambulant...
