| Kim et al. 2015 [20] | Glycopyrrolate vs atropine in combination with neostigmine after TURBT | Scheduled for TURBT | 74 | Incidence of catheter-related bladder discomfort postoperatively (primary) | Numerical rating scale |
• Incidence of CRBD was significantly lower in the glycopyrrolate group than in the atropine group postoperatively • No difference in pain scores |
| Huang et al. 2015 [21] | Pirarubicin combined with hyaluronic acid vs pirarubicin alone after TURBT | Scheduled for TURBT | 127 | Recurrence (efficacy) (primary) | Visual analogue scale |
• No difference in treatment efficacy • The VAS for bladder pain was significantly lower, at the end of the induction cycle, in the experimental group |
| Kim et al. 2015 [22] | Dexmedetomidine vs placebo during TURBT | Scheduled for TURBT | 109 | Incidence of catheter-related bladder discomfort postoperatively (primary) | Numerical rating scale |
• Incidence of CRBD was significantly higher in the control group • The postoperative pain score was higher in the control group |
