Dorsal Penile Block for Post-Robotic Prostatectomy Foley Discomfort

Columbia University

Overview

The indwelling urethral foley is a major source of discomfort following radical prostatectomy. Our hypothesis is that intra-operative dorsal penile nerve block with bupivacaine may decrease immediate post-operative foley discomfort.

Patients undergoing robot-assisted radical prostatectomy (RARP) will be randomized in a double-blind placebo controlled manner to undergo penile ring block injection at the time of skin incision closure. A visual analog scale (VAS) based questionnaire including newly developed foley discomfort scores will be administered at various time points post-operatively.
