The primary outcome was patient\u2010reported urinary continence status at 1, 3, 6, 12 and 24\u2009months postoperatively, with continence defined as 0 pad\/day. The primary exposure was BNS (largest diameter) measured intraoperatively just before performance of vesicourethral anastomosis. Other covariates included age, body mass index, NCCN risk category, nerve\u2010sparing, membranous urethral length measured intraoperatively and weight of the resected specimen.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Well\u2010preserved neurovascular bundle (bilateral\/unilateral\/none) was highly correlated with urinary continence status at every point after surgery. No difference could be seen between the group with BNS \u226417\u2009mm and the &gt;17\u2010mm group at 1, 3 and 6\u2009months after surgery, but there was better urinary rate of continence in narrow BNS group (\u226417\u2009mm) at 12 and 24\u2009months after surgery. Multivariate analysis showed both nerve sparing and bladder neck diameter to be independent factors affecting urinary continence at 12 and 24\u2009months after surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Preservation of neurovascular bundles was associated with better urinary continence after surgery.
