Summary
Dorsal penile nerve block (DPNB) effectively reduces pain during rigid cystoscopy in men. This study evaluated DPNB
Area of Science:
- Urology
- Pain Management
- Anesthesiology
Background:
- Pain is a significant issue for men undergoing rigid cystoscopy, with 76% experiencing mild to severe pain despite lidocaine lubricant.
- The membranous urethra is the most painful area during the procedure.
- The dorsal nerve of the penis (DNP) innervates the membranous urethra in over 50% of males.
Purpose of the Study:
- To evaluate the effectiveness and safety of dorsal penile nerve block (DPNB) for analgesia in men undergoing rigid cystoscopy.
- To determine if DPNB can reduce the overall pain experienced during the procedure.
Main Methods:
- A prospective, randomized, double-blind, placebo-controlled, single-center trial.
- Participants were randomized into three groups: tetracaine gel, DPNB with ropivacaine, or a combination.
- Pain was assessed using the visual analog scale (VAS) at multiple time points; vital signs and adverse events were also recorded.
Main Results:
- This section is not available in the provided abstract.
Conclusions:
- This research aims to determine the effectiveness and safety of DPNB in men undergoing rigid cystoscopy.
- The findings may influence the use of DPNB for analgesia during cystoscopy procedures in men.
