Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Catheter-related bladder discomfort (CRBD) is not uncommon in male patients under general anesthesia, and it may cause patient agitation and exacerbated postoperative pain. In this study, the investigators will enroll male patients undergoing elective colonal and rectal surgery with surgical duration of at least 2 h, requiring catheterization of the urinary bladder with urinary catheterization after anesthetic induction, and compare preoperative education with image illustrations combined with local tetracaine mucilage vs. local tetracaine mucilage alone in alleviating CRBD during the post-operative period.
