Abstract
Purple urine bag syndrome is a rare disorder, in which the plastic disposable urinary catheter bag turns purple or blue following hours or days of urinary catheterization. This investigation reports the case of a 58 years woman was previously diagnosed with CKD resulting from diabetic nephropathy and also had a positive history of hypertension who presented with purple urine bag syndrome.
Highlights
Purple urine bag syndrome (PUBS) refers to purple discoloration of the urinary drainage bag occurring in patients on long-term urinary catheterization (Figure 1)
This phenomenon results from bacterial fermentation of indoxyl sulfate to indigo and indirubin, which dissolves in the plastic of urine bags [1]
It is noteworthy that despite the frequent occurrence of UTIs in patients with risk factors for PUBS, the condition is uncommon in clinical practice
Summary
Purple urine bag syndrome (PUBS) refers to purple discoloration of the urinary drainage bag occurring in patients on long-term urinary catheterization (Figure 1). It is a rare manifestation associated with urinary tract infection caused by bacteria that produce sulfatase or phosphatase. This phenomenon results from bacterial fermentation of indoxyl sulfate (indican) to indigo and indirubin, which dissolves in the plastic of urine bags [1]. Constipation, urinary tract infection, dementia, alkaline urine, high urinary bacterial counts and iron deficiency anemia are associated with PUBS. On day 3 urine culture report shown the growth of proteus mirabilis with colony count of 1,20000 CFU/ml
