N2 - Background and Objectives: Loss of erectile function is common after prostatectomy, and surgeons have long sought techniques that reduce this adverse outcome. This study was conducted to assess erectile function after robot- assisted laparoscopic prostatectomy, with and without hydrodissection (HD) of the neurovascular bundles (NVBs). Methods: Using a database of 335 consecutive RALP procedures conducted by 2 surgeons, we identified all nervesparing surgeries performed by HD or standard dissection (SD). The primary and secondary endpoints were Sexual Health Inventory for Men (SHIM) scores and surgical margin positivity, respectively. Subset analyses were performed on men with preoperative SHIM scores ≥17. Determinants of the postoperative SHIM score were evaluated by multivariate linear regression. Results: Among men with preoperative SHIM scores ≥17 who underwent bilateral complete nerve sparing (n = 73), mean preoperative SHIM scores were similar in the HD and SD groups, but were significantly higher in the HD group at 6 months (16.1 ± 8.6 vs 8.3 ± 8.1; P =.024) and >1 year after surgery (16.9 ± 7.1 vs 9.1 ± 6.4; P =.004). According to multivariate linear regression analysis including all patients, HD at RALP (odds ratio [OR] 6.9; 95% confidence interval (CI) 2.8 –11.0; P =.001) and preoperative SHIM score were independent predictors of erectile function at >1 year after surgery. There was no significant difference in surgical margin positivity between groups (P =.36). Conclusion: HD of the NVB appears to improve erectile function after RALP.
