The majority of studies have evaluated the use of DPNB prior to circumcision in the pediatric population. To date, few studies have examined the role of DPNB prior to inflatable penile prosthesis (IPP) implantation. The purpose of this study was to assess the efficacy of local penile nerve block prior to IPP implantation for post-operative pain control. METHODS Institutional Review Board approval was obtained. Patients with erectile dysfunction scheduled for IPP implantation were approached for study participation. Patients were excluded if they had a previous IPP scheduled for revision or replacement or were undergoing additional procedures during the same operative session (manual modeling, concomitant artificial urinary sphincter placement, etc.). Patients were then randomized to either DPNB with a 50/50 mixture of 1% lidocaine and 0.5% bupivacaine without epinephrine or injectable saline placebo. Only the Resident surgeon assisting in the case was aware of randomization. All procedures were performed by a single surgeon (CCC). Postoperatively, patients were asked to rate their pain using a Visual Analog Scale hourly while in recovery, at 4 hours, and at 23 hours postoperatively. Total narcotic usage was also measured. RESULTS A total of 18 patients underwent randomization with 9 patients in each group. Baseline demographic data were similar in each group. There was a statistically significant reduction in postoperative pain at 4 hours in the treatment group compared to placebo (VAS 1.7 vs. 5.8, p=0.0004). Immediate postoperative pain in the recovery area approached statistical significance in the treatment versus placebo groups (VAS 2.6 vs. 5.3, p=0.06). Narcotic usage was similar among both groups. There were no perioperative or early postoperative complications in either group. CONCLUSIONS Dorsal penile nerve block is safe and effective for reducing pain in the early postoperative period following penile prosthesis implantation. © 2011 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 185Issue 4SApril 2011Page: e241 Advertisement Copyright & Permissions© 2011 by American Urological Association Education and Research, Inc.MetricsAuthor Information Patrick Selph Chapel Hill, NC More articles by this author Joshua Langston Chapel Hill, NC More articles by this author Sachin Vyas Chapel Hill, NC More articles by this author Mathew Raynor Chapel Hill, NC More articles by this author Angela Smith Chapel Hill, NC More articles by this author Sharon Kapeluk Chapel Hill, NC More articles by this author Culley Carson Chapel Hill, NC More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
