Abstract
Objectives
This study evaluated the association of patient age and preoperative prostate MRI-derived anatomical parameters with postoperative urinary incontinence (UI) and urinary continence (UC) recovery after robot-assisted radical prostatectomy (RARP).
Methods
We retrospectively included 118 patients who underwent RARP between 2022 and 2024 and had preoperative prostate MRI. Patient age and continence status at 1, 3, 6, and 12 months were obtained from medical records. Levator ani muscle (LAM), obturator internus muscle (OIM), and pubococcygeus muscle thicknesses were measured at their thickest points on axial and coronal T2-weighted images. Membranous urethral width (MUW), length (MUL), and angle (MUA) were measured, and prostate volume was calculated. UC was defined as no pad use or one safety pad per day (used for reassurance or for occasional minimal drops of urine), whereas UI was defined as the use of one or more pads per day that became wet because of urine leakage. Associations were evaluated using group comparisons, Kaplan–Meier analysis, and exploratory Cox and logistic regression models.
