When patients were divided into early and late continence groups based on urinary continence at 3\u2009months after robotic-assisted radical prostatectomy, no significantly different clinical characteristics or surgical outcomes were found. However, the mean membranous urethral length (18.5\u2009mm for the early continence group vs. 16.9\u2009mm for the late continence group), levator muscle width (7.1 vs. 6.5\u2009mm, respectively), and bladder neck width on the trigone side (7.2\u2009mm vs. 5.4\u2009mm, respectively) were significantly different between groups (all <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). Multivariate logistic regression analysis showed that membranous urethral length (odds ratio, 1.227; 95% confidence interval, 1.011\u20131.489; <jats:italic>p<\/jats:italic>\u2009=\u20090.038) and bladder neck width (odds ratio, 1.585; 95% confidence interval, 1.050\u20132.393; <jats:italic>p<\/jats:italic>\u2009=\u20090.028) were associated with the period of early urinary continence.<\/jats:p>\n              <\/jats:sec>\n              <jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Postoperative membranous urethral length and bladder neck width were significantly associated with early urinary continence recovery after robotic-assisted radical prostatectomy.
