OBJECTIVE: • To determine if sodium bicarbonate (Ural) reduces painful voiding after flexible cystoscopy. PATIENTS AND METHODS: • 300 patients over 18 years old undergoing elective flexible cystoscopy were enrolled in a randomized, double-blinded, placebo-controlled trial. Patients with active urinary tract infections, indwelling urinary catheters and/or requiring additional procedures such as biopsy and dilatation were excluded. • Painful voiding was quantified using a pain analogue scale from 0 to 10. Pre-existing painful voiding, previous experience with Ural and flexible cystoscopy were recorded. • Flexible cystoscopy was performed to a standard protocol. Patients were randomised after r..View full abstract
