Nerve Bundle Hydrodissection and Sexual Function after Robot Prostatectomy

摘要

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 nerve-sparing 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: = .36). CONCLUSION: HD of the NVB appears to improve erectile function after RALP.
