Abstract:
Purple urine bag syndrome (PUBS) is an unusual manifestation of urinary tract infection, characterized by purple discoloration of urine. Due to its rarity, it can be challenging for some physicians to manage it properly. In addition, its striking appearance can cause concern to some patients. This condition usually occurs in the debilitated geriatric population with prolonged use of an indwelling urinary catheter. However, our case highlights the development of PUBS in a young adult with a relatively short period of urinary catheterization.
