A new method in robotic-assisted laparoscopic radical prostatectomy: personalised neuroprotective surgery with neuromonitoring system-randomised controlled study.

Purpose: Erectile dysfunction is one of the important morbidities following the radical prostatectomy (RP) surgeries. The goal of this research is to investigate the contribution of intraoperative neuromonitorisation method (IONM) on postoperative erectile function in patients who underwent robotic-assisted laparoscopic radical prostatectomy (RALP) with the localise prostate cancer (LPCa).

Materials And Methods: In this randomised controlled study contains 88 patients with LPCa were classified based on D'Amico Risk Classification. 61 patients who met the necessary criteria were divided into two groups as neuromonitorisation group (n = 30) and control group (n = 31). All patients were operated under general anaesthesia. All patients included in the study underwent RALP by robotic-assisted system. For the neuromonitorisation, IONM electromyography electrodes were placed to the right and left cavernous bodies in neuromonitorisation group. Impulses in the corpora cavernosa were considered significant. Postoperative erectile functions were determined according to the 3th and 6th month IIEF-5 scores. Demographic data, operative procedures, Gleason scores, final pathology, surgery border, PSA, and IIEF-5 score of patients were recorded.

Results: No statistically difference was found between the groups in terms of demographic data, operative procedures, Gleason scores, final pathology, surgery border, and third-month PSA levels (p > 0.05). There was statistically difference between the postoperative third and 6-month IIEF-5 score in neuromonitorisation group (p < 0.05).

Conclusion: In the IONM technique, high rate of improvement in erectile function was observed in the early period thanks to personalised neuroprotective surgery applied to patients.
