Prolonged Indwelling Percutaneous Nephrostomy Leading to Purple Urinary Bag Syndrome in Palliative Care Setting: A Case Report.

Purple urine bag syndrome (PUBS) is a complication and a rare phenomenon associated with bacterial colonisation in bladder catheters in which urine turns purple in the tubing and the catheter bag. This condition can be distressing and panicking for the patients and their families as well as the medical staff caring for them. It is an interesting and unusual presentation that affects people with long-term indwelling catheters and chronic constipation. We report one such case in our hospital, a 73-year-old woman with stage 4 cancer of the vaginal vault, post-bilateral percutaneous nephrostomy (PCN) 4 months ago, currently on best supportive care, presented to the emergency room with symptoms of urosepsis, while a purple urine bag may appear innocuous and not need any particular care beyond replacing the catheter and giving the patient the proper antibiotics, it may indicate an occult urinary tract infection (UTI), which can have catastrophic effects in a patient using a urinary catheter for an extended period of time. Only a few examples of PUBS with an underlying nephrostomy have been documented in the literature. This is a case of a palliative care patient who had a poor prognosis despite receiving the right antibiotic treatment for an upper UTI that caused purple staining of the PCN catheter bag. Using this case report as a guide, we could manage a complex UTI in a palliative care context.

Purple urinary bag syndrome: Our experience.

Background: Purple urinary bag syndrome (PUBS) is a visually striking and rare manifestation of urinary tract infection characterised by purple discolouration of the catheter and the urobag, which are seen primarily in patients who are on long-term indwelling catheter. This rare syndrome results due to the breakdown of indole, a by-product of dietary tryptophan metabolism, to coloured pigments indigo and indirubin by urinary bacteria, which reacts with the catheter and the bag to impart a purple colour. Methods: This was a prospective observational study, wherein all cases of PUBS diagnosed between March 2012 and February 2020 were analysed and followed up. Results: A total of five patients were presented with PUBS. Among them, four were women, and four were chronically constipated. All of them were elderly and debilitated with either being bed bound or having restricted mobility. Three of them had associated chronic kidney disease. All of them were treated successfully with change of catheters and antibiotics. Conclusion: This rare but alarming condition occurs in elderly patients who are on long-term indwelling catheters. The diagnosis is visually apparent, and the treatment may be just a simple change of catheter with oral antibiotics. The awareness may help in correct diagnosis and treatment.

Purple urine bag syndrome: An unusual but important manifestation of urinary tract infection. Case report and literature review.

Purple urine bag syndrome is a rare albeit alarming purple discolouration of the urine typically seen in elderly ladies with constipation, urinary tract infection and concurrent urinary catheterisation. In this concise review, we report the pathophysiology of this condition and the case of one patient who developed this interesting phenomenon.

Bladder perforation during laparoscopy detected by gaseous distention of the urinary bag -A report of two cases-.

Bladder perforation during laparoscopy is a recognized, uncommon complication. We present two cases of bladder perforation during laparoscopic gynecologic operations that were detected by gaseous distention of the urinary bag. Bladder perforation occurred through laparoscopic division of adhesion. One bladder perforation was repaired laparoscopically, and the other case was repaired by laparotomy during the same general anesthesia. In this report, we present evidence that monitoring a gas-distended urinary bag during a laparoscopic procedure can help detect intraoperative bladder perforation.

Síndrome de la bolsa de orina púrpura / Purple urine bag syndrome

Se presenta el caso de un paciente masculino de 62 años remitido por oncología para estudio por presentar orina de color morado. Desde hace tres meses tiene sonda vesical permanente por retención urinaria posterior a una resección quirúrgica de una metástasis cerebral por tumor primario a nivel pulmonar, tiene pendiente radioterapia holoencefálica y posterior quimioterapia sistémica. La única medicación que tomaba de manera intermitente era omeprazol, refería además anorexia y náuseas. La bolsa urinaria contenía orina de color morado y a la extracción aparecía turbia. El análisis de la orina fue compatible con infección urinaria. El color de la orina en la bolsa fue motivo de una interesante discusión científica. Se discuten los mecanismos a través de los cuales la orina toma dicho color (Acta Med Colomb 2011; 36: 38-40).

The case is presented of a 62-year-old male patient who was referred by the Oncology Department for evaluation of purple-colored urine. Over the past three months the patient has had an indwelling catheter because of urinary retention after surgical resection of a brain metastasis of a lung tumor. The patient is to be treated with holoencephalic radiotherapy and afterwards with systemic chemotherapy. The only current medication was omeprazole, which he took intermittently. He also complained of anorexia and nausea. The urinary bag contained purple-colored urine, which appeared turbid upon extraction. Urinalysis was consistent with urinary tract infection. The color of the urine gave rise to an interesting scientific discussion. The mechanisms are discussed through which urine takes a purple color (Med Colomb 2011; 36: 38-40).
