Introduction: Purple urine bag syndrome is a rare clinical entity characterized by purple discoloration of the urinary catheter and urinary drainage bag in chronically catheterized patients. Though it can be alarming to patients and clinicians, it is considered benign but can indicate an underlying urinary tract infection. Case Series: The first case was a 68-year-old woman with multiple comorbidities who was admitted to the orthopedic ward with a close fracture of the neck of the right femur. She was bedridden and had an indwelling urethral catheter. Her urine bag was noticed to stain purplish 22 days after bladder catheterization. Urine culture showed a heavy mixed growth. A change of urinary catheter and drainage bag led to a resolution of the condition. The second case was a 58-year-old male who was admitted on account of decompensated liver cirrhosis from chronic hepatitis C virus infection. He also had quadriparesis due to a traumatic cervical spine injury, urine retention, and constipation. On day 24 of his admission, his urine bag was stained with a purplish hue. A urine culture grew Klebsiella oxytoca. The urine bag remained clear and contained amber-colored urine after catheter changes and antibiotic treatment for cystitis. Conclusion: Purple urine bag syndrome can be alarming to the patient and caregiver who need to be reassured of its benign nature. Urine culture would identify any associated infection. Good catheter care, control of risk factors including constipation and antibiotic treatment for symptomatic urinary tract infection leads to the resolution of the discoloration.

“…Although most of the reported cases of PUBS are benign, 5 6 11 some reports have associated PUBS to severe complications such as severe sepsis requiring aggressive treatment in the intensive care unit 8 and Fournier's gangrene in an immunocompromised patient. 12 Since urine discoloration is not a sign of UTI, PUBS is therefore classified as asymptomatic bacteriuria.…”

Purple urine bag syndrome is a rare clinical entity commonly seen in elderly females with a long-term urinary catheterization. It presents as purple discoloration of the patient's plastic urine bag and tubing. We report the first case of this rare entity from Central Africa. We present the case of an 80-year-old female with purple urine associated with signs of urinary tract infection. Her symptoms resolved after 3 days of intravenous antibiotic treatment and diet modification. Purple urine bag syndrome remains rare, especially in African literature. Awareness of this benign syndrome is necessary for clinicians so as to adequately manage up to and including the associated anxiety.

Background/Aims: Purple urine bag syndrome (PUBS) is an uncommon clinical entity characterized by purple urine discoloration in the setting of urinary tract infections. Pa-thophysiology of PUBS has been correlated to aberrant metabolism of tryptophan. Multiple predisposing factors have been recognized, namely: female gender, advanced age, constipation, institutionalization, long-term catheter-ization, dementia and chronic kidney disease. Herein, we present a comprehensive review of all PUBS cases reported in PubMed, focusing on the predisposing factors and the microorganisms related to PUBS. Methods: We performed a search in PubMed database for articles referring to PUBS, published in English, French, Spanish and German from January 1978 until November 2017. The literature recruitment strategy was based on several keywords and Medical Subject Heading combination such as “purple urine bag syndrome” or PUBS or “urine discoloration”. The finally selected articles were categorized into case reports/series (88 articles including 112 patients) and studies (10 articles including 134 patients). Demographical data as well as predisposing factors were recorded and further analyzed. Results: According to our findings, mean age of PUBS patients was 78.9 ± 12.3 years, 70.7% were female while 90.1% were suffering from constipation, 76.1% were in a bedridden situation, 45.1% were experiencing long-term catheterization, 42.8% had been diagnosed with dementia, 14.3% had recurrent urinary tract infections and 14.1% were chronic kidney disease patients. 91.3% of patients presenting with PUBS alkaline urine were observed while the most common microbe in urine cultures was E. coli. Conclusions: PUBS is considered benign process in the majority of catheterized patients. Clinicians should be aware of the syndrome that may indicate serious comorbidities.
