By Mayo Clinic staffRisks of urine cytology testing depend on how your urine is collected. Most often urine is collected by urinating into a sterile container, which carries no risk. If your urine is collected by inserting a hollow tube (catheter) into your urethra, there is a risk of urinary tract infection. Ask your doctor about the specific risks of your procedure.
