AB - An 82-year-old patient presented to urology outpatients for a routine 6-week change of her suprapubic catheter. The urine collection bag was a deep purple throughout the bag, extending into the catheter tubing (Figure 1).Figure 1.Urine collection bag with tubing. The bag has a small volume of urine which was only mildly stained. The catheter itself was not this colour.Examination of the urine within the bag did not indicate the same level of colour change. Urine dipstick revealed the presence of leucocytes and nitrates and a pH of 8.5, with a diagnosis of purple urine bag syndrome. Subsequent urine microscopy, culture and sensitivity indicated the presence of Proteus mirabilis. The patient denied any systemic symptoms of a urinary tract infection so the suprapubic catheter was changed and the patient was discharged home with sensitive oral antibiotics.Gross examination of the collected specimen revealed sediment which microscopy revealed to be phosphate crystals (Figure 2). Purple urine bag syndrome is a harmless side effect of a highly alkaline urinary tract infection which requires treatment.Figure 2.Microscopy of urine from bag at 10x magnification indicating the phosphate crystals deposited.
