ABSTRACT
AIM: To determine optimum duration of intraurethral 2% lidocaine jelly for pain relief during outpatient rigid cystoscopy. MATERIALS AND METHODS: This prospective randomized study was conducted between June 2012 and November 2013. Four hundred consecutive adult males requiring diagnostic rigid cystoscopy were randomized into four groups depending on intraurethral 2% lidocaine jelly dwell time before rigid cystoscopy: jelly was instilled 5, 10, 15, and 20 minutes before start of the procedure in group A, B, C, and D patients, respectively. The patients' age, patient-reported preoperative anxiety score, patient-reported intraoperative pain score, the surgeon-reported patient's pain score, and the duration of rigid cystoscopy were recorded and analyzed. RESULTS: The mean age, patient-reported preoperative anxiety score, and duration of rigid cystoscopy were similar between the four groups with no significant difference noted between them. The least and highest mean patient-reported and surgeon-reported intraoperative pain scores were reported in group C (1.49±0.82 and 1.58±0.67) patients and group A (4.86±1.24 and 4.04±1.11) patients, respectively, while no significant difference was found in these scores between group C and D patients. CONCLUSION: For male patients undergoing diagnostic rigid cystoscopy, an intraurethral dwell time of 15 minutes (of 20 mL 2% lidocaine jelly) provided optimum pain relief.
