Nerve Graft with Radical Prostatectomy


Nerve grafting at the time of radical prostatectomy has been proposed to reduce the risk of postoperative erectile dysfunction. In particular, spontaneous erections are absent in individuals whose extent of prostate cancer requires bilateral resection of the neurovascular bundles as part of the radical prostatectomy procedure.

The sural nerve is most commonly used as it is considered expendable and has been used extensively in other nerve grafting procedures.  As applied to prostatectomy, a portion of the sural nerve is harvested from one leg and then anastomosed to the divided ends of the cavernous nerve.

Other grafting techniques, including the use of commercially available nerve allografts (AvanceĀ® Nerve Graft) are currently being investigated. 




The evidence for nerve grafting in individuals who have radical prostatectomy with resection of neurovascular bundles includes one randomized controlled trial (RCT), cohort studies and case series.  The RCT did not find that unilateral nerve grafting was associated with a statistically significant improvement in potency rates at two years post-surgery.  Cohort studies, limited by lack of randomization and blinding, also did not result in better outcomes with nerve grafting.  The evidence is insufficient to determine the effects of the technology on health outcomes.
