Urinary catheterization can cause catheter-related bladder discomfort (CRBD). Ketorolac is widely used for pain control. Therefore, we evaluated the effect of ketorolac on the prevention of CRBD in patients undergoing robot-assisted laparoscopic radical prostatectomy (RALP). All patients were randomly allocated to the ketorolac group or the control group. The primary outcome was CRBD above a moderate grade at 0 h postoperatively. CRBD above a moderate grade at 1, 2, and 6 h was also assessed. Postoperative pain, opioid requirement, ketorolac-related complications, patient satisfaction, and hospitalization duration were also assessed. The incidence of CRBD above a moderate grade at 0 h postoperatively was significantly lower in the ketorolac group (21.5% vs. 50.8%, p = 0.001) as were those at 1, 2, and 6 h. Pain scores at 0 and 1 h and opioid requirement over 24 h were significantly lower in the ketorolac group, while patient satisfaction scores were significantly higher in the ketorolac group. Ketorolac-related complications and hospitalization duration were not significantly different between the two groups. This study shows ketorolac can reduce postoperative CRBD above a moderate grade and increase patient satisfaction in patients undergoing RALP, suggesting it is a useful option to prevent postoperative CRBD.
