2.4. Standard Urine Culture
STERILE, RECURRENT URINARY TRACT INFECTION
At the baseline and follow-up visits, a urine sample was collected using sterile intermittent catheterization to assess if a current urinary tract infection was present. Ten mL of urine was collected in a Urine Monovette with boric acid (Saarstedt, Germany) and analyzed by standard urine culturing.
