Abstract

BackgroundPurple color of urine is alarming and may indicate a serious underlying pathology. Purple discoloration of the urinary catheter bag is uncommon and is caused by urinary tract infection with certain organisms.Case presentationWe present a case of this rare phenomenon in a benign prostate hyperplasia patient with indwelling catheter who also has diabetes mellitus and chronic renal disease. We also discussed proposed etiology and pathophysiology of purple urine bag syndrome.ConclusionAttempt to make the patient catheter free after stabilizing the patient is also the key point in its management. Although purple urine bag syndrome is not an aggressive pattern, it is an indicator for urosepsis.
