Study of mirabegron and solifenacin in the improvement of catheter-related bladder discomfort in patients undergoing transurethral resection: A case–control study

The goal of this study was to see if using mirabegron, solifenacin, or placebo may help patients with transurethral resection avoid catheter-related bladder discomfort (CRBD). METHODS: Patients who underwent transurethral surgery and were given a catheter for 3 days after surgery were chosen for this study. The enrolled patients were separated into 3 groups: mirabegron (M), solifenacin (S), and a blank control group (C). All patients had their overactive bladder symptoms score (OABSS) and blood pressure checked before surgery. The CRBD, blood pressure, and heart rate were measured at 6, 24, 48, and 72 hours after surgery. The OABSS and side effects were documented on the 7(th) day. RESULTS: The 104 patients in this trial were randomized into 3 groups at random: M, S, and C. The ultimate follow-up was completed by 99 patients, including 33 in group M, 33 in group S, and 33 in group C. The OABSS, CRBD, and blood pressure in groups M and S were similar before and after surgery (P > .05). Groups M and S performed much better on the OABSS and CRBD than group C (P < .05). There were no significant differences in blood pressure between the 3 groups (P > .05). There were no significant differences in the occurrences of new onset dry mouth (P = .84) or constipation (P = .64) among the 3 groups. CONCLUSION: Mirabegron is comparable to solifenacin as an alternative for the prevention of CRBD, making it a viable option for CRBD prevention.
