Abstract

Purpose: To explore whether prostatectomized men report improved post-operative erectile function and urinary control dependent on the application of intra-operative frozen section examination (NeuroSAFE) during nerve-sparing radical prostatectomies (NS-RPs).

Methods: Pre- and post-RP responses to the sexual domain and the urinary incontinence subscale of EPIC-26 were analyzed in 95 and 312 men from a NeuroSAFEGroup (Martini-Klinik, Hamburg, Germany) and a Non-NeuroSAFE Group (Oslo University Hospital, Norway), respectively, undergoing NS-RPs for ≤ cT2 prostate cancer. All patients had intra-prostatic tumors as evaluated by Digital Rectal Examination. Statistical significance in bivariate and multi-variable analyses: p < 0.05.

Results: With similar oncological outcomes and not associated with the performance of bilateral or unilateral NS-RP within each group patients from the NeuroSAFE Group had better sexuality outcomes than those from the NonNeuroSAFE Group (p < 0.01). Age and pre-RP sexual function represented significant co-variables. In pre-RP potent men, erectile function was preserved in 74% of men in the NeuroSAFE Group and in 46% in those from the NonNeuroSAFE Group (p < 0.01). Any superior continence-saving effect of NeuroSAFE was limited. The non-randomized small-sized observational study design represents the observations’ main limitation.

Conclusions: Our study indicates that NeuroSAFE contributes to preservation of post-RP erectile function. If confirmed in a randomized trial the NeuroSAFE should be applied in patients undergoing NS-RP for maximal preservation of post-RP sexual function.
