Nakane A, Kubota H, Noda Y, et al. - Data from 73 individuals who underwent postoperative prostate MRI after robotic-assisted radical prostatectomy between 2013 and 2018 was retrospectively reviewed to examine the influence of postoperative membranous urethral length and other anatomic features of the pelvic floor shape as measured by MRI on the betterment in the continence after robotic-assisted radical prostatectomy. When patients were categorized into early and late continence groups on the basis of urinary continence at 3 months following robotic-assisted radical prostatectomy, no significantly distinctive clinical features or surgical outcomes were discovered. Nevertheless, the mean membranous urethral length, levator muscle width, and bladder neck width on the trigone side were significantly distinctive among groups. Multivariate logistic regression analysis exposed that membranous urethral length and bladder neck width had a correlation with the period of early urinary continence. In conclusion, following robotic-assisted radical prostatectomy, postoperative membranous urethral length and bladder neck width were significantly correlated with early urinary continence recovery. Moreover, to attain optimal continence outcomes following robotic-assisted radical prostatectomy, it is profoundly suggested that surgeons concentrate on preserving the membranous urethral length and improving the bladder neck width on the trigone side during surgery.
