Brief Summary

Catheter-related bladder discomfort (CRBD) secondary to an indwelling urinary catheter is defined as an urge to void or discomfort in the supra-pubic region. This symptom complex may cause patient agitated and exacerbated postoperative pain. In clinic, dorsal penile nerve block (DPNB) was applied for penile surgery including circumcision and some anterior urethra surgery. The investigators hypothesize that DPNB relive CRBD for male patients with indwelling urinary catheter under general anesthesia.
