Intravesical ropivacaine as a novel means of analgesia post robot assisted radical prostatectomy: A randomized, double blind, placebo controlled trial - Abstract

Background and Purpose:This study evaluates the safety and efficacy of intravesical ropivacaine as part of a mulitimodal approach to the provision of analgesia following robot assisted radical prostatectomy (RARP).

Patients and Methods:In this double blind, placebo controlled trial, 40 patients scheduled to undergo RARP for treatment of localized prostate cancer by a single surgeon (SP) were randomized 1:1 to receive either alkalinized intravesical ropivacaine or placebo (0.9% sodium chloride) at the completion of the vesico-urethral anastomosis. A standardized general anesthetic was administered in each case. The primary outcome was a reduction in post-operative pain as assessed by a visual analogue scale (VAS). The need for alternate analgesic agents was recorded. Adverse events related to the administration of intravesical ropivacaine were documented prospectively.

Results:No serious adverse events related to the administration of intravesical ropivacaine were identified. In the ropivacaine group, there was a significant reduction in the cumulative required dose of ketoralac relative to placebo at 6 hours post-operatively. There was no statistically significant difference between the groups with regard to pain scores or narcotic use at any time point.

Conclusions: Intravesical administration of ropivacaine may be used safely in the context of RARP and is associated with a significant, albeit modest reduction in the need for supplementary analgesic agents, but did not result in a decrease in post-operative pain scores.
