This study was designed to evaluate association of urethral parameters on preoperative magnetic resonance imaging (MRI) and immediate recovery of urinary continence following Retzius-sparing robot assisted radical prostatectomy (RS-RARP).<h4>Methods</h4>This retrospective cohort study enrolled 156 patients with clinically localized prostate cancer who underwent MRI before RS-RARP. We measured the following structures on preoperative MRI: minimal residual membranous urethral length (mRUL), peri-urethral sphincter complex (PSC) thickness, urethral wall thickness (UWT), the thicknesses of the levator ani muscle (LAM) and obturator internus muscle (OIM)Translational andrology and urology501-509https://www.ebi.ac.uk/biostudies/studies/S-EPMC7215013biostudies-literatureAssociation of preoperative urethral parameters on magnetic resonance imaging and immediate recovery of continence following Retzius-sparing robot-assisted radical prostatectomy.PMC7215013Li WLi XLi YYang YQiu XLu WChen MGuo HGao JZhuang JfalseAssociation of preoperative urethral parameters on magnetic resonance imaging and immediate recovery of continence following Retzius-sparing robot-assisted radical prostatectomy.<h4>Background</h4>Studies regarding predictive factors of urinary continence following Retzius-sparing radical prostatectomy (RP) is limited.
