ABSTRACT
Background@#This study aimed to present the surgical facilitation of neurovascular bundle (NVB) sparing using the toggling technique (30° lens down/up switching) and to evaluate erectile dysfunction (ED) recovery after robot-assisted radical prostatectomy (RARP). @*Methods@#We assessed 144 patients (group with toggling, n = 72; group without toggling, n = 72) who underwent RARP with bilateral NVB sparing using propensity score matching.Inclusion criteria were ≥ 1 year follow-up and preoperative potency as per the Sexual Health Inventory for Men (SHIM) questionnaire (≥ 17 points). Recovery of ED after RARP was defined as return to baseline sexual function or self-assessment regarding successful intercourse. The subjective surgeon’s nerve sparing (SNS) score and tunneling success rates were used to evaluate surgical facilitation. The recovery rate of ED between the groups was analyzed using Kaplan-Meier analysis. @*Results@#A better ED recovery trend was confirmed according to the SNS score (R 2 = 0.142, P = 0.004). In the analysis of NVB sparing ease, the toggling group showed higher SNS scores (on right/left side P = 0.011 and < 0.001, respectively) and overall tunneling success rates (87% vs. 74%, P = 0.001) than the group without toggling. Overall, ED recovery rates were 82% (59/72) and 75% (54/72) in the groups with and without toggling, respectively, at the 1-year follow-up (P = 0.047), and the toggling group showed a faster ED recovery rate at 3 months (47% vs. 35%, P = 0.013). In a specific analysis of the potent cohort (< 60 years, bilateral full NVB spared, SHIM score ≥ 22), the ED recovery rate reached 87% (14/16) in the toggling group. @*Conclusion@#The retrograde early release with the toggling technique improves the facilitation of NVB sparing, leading to improved ED recovery.
