Detailed Summary

Catheter-related bladder discomfort (CRBD) is common in patients awaking from general anesthesia with an urinary catheter. We suppose that that use of dexmedetomidine and/or esketamine during anesthesia may reduce the occurrence of CRBD. This 2x2 factorial randomized trial is designed to explore the effects of esketamine, dexmedetomidine, and their combination on the occurrence CRBD in patients undergoing transurethral urological surgery.
