purpose:The aim of the study was to examine the influence of the surgical approach for robot-assisted laparoscopic prostatectomy(RALp)on long-term urinary continence status in the era of self-reported functional status measures using the Expanded prostate Can-cer Index Composite 26.Materials and methods:This is a prospective evaluation of 232 patients undergoing RALp between September,2019 and September,*** continence status and postoperative incontinence(pad usage)were evaluated 12 months after RALp using Expanded prostate Cancer Index Composite 26 *** were categorized according to their surgical approach and outcome into the following groups:successful nerve sparing(NS),primarily without nerve sparing(***),and no nerve sparing by secondary resection(NNS by SR).The median levels of their questionnaire outcomes were evaluated and compared using the Wilcoxon rank sum test with continuity correction.Results:Urinary continence status 12 months after RALp differed significantly between the NS and ***(p=0.0071)and the NS and NNS by SR(p=0.0076)*** was no significant difference between the *** and NNS by SR(p=0.53)*** usage 12 months after RALp had no significant difference with regard to SR of the neurovascular bundle(p=0.14).Conclusions:patient-reported outcomes of long-term urinary continence status seem to show no difference in postoperative conti-nence,regardless of whether a non-nerve-sparing result was planned or reached through ***,preservation of neurovascular bundle seems to lead to better long-term continence rates.
