Dorsal penile nerve block alleviates pain in men undergoing rigid cystoscopy: A single-center, randomized, double-blind, and placebo-controlled trial.

ABSTRACT:

Objective

To assess the effectiveness and safety of dorsal penile nerve block (DPNB) compared with tetracaine gel in analgesia for men undergoing rigid cystoscopy.

Patients and methods

This study was conducted as a prospective, randomized, double-blind, placebo-controlled, and single-center trial. Men undergoing diagnostic rigid cystoscopy were randomly allocated into one of three groups (n = 86 each): (1) tetracaine gel group (DPNB with saline), (2) DPNB group (DPNB with ropivacaine + plain lubricant), and (3) combination group (DPNB with ropivacaine + tetracaine gel). The primary outcome was visual analog scale (VAS) for pain at cystoscopic inspection of the external sphincter.

Results

VAS (median [interquartile]) at inspection of the external sphincter was signific
