Predictors of short and long term urinary incontinence after radical prostatectomy in prostate MRI: Significance and reliability of standardized measurements

Highlights: • MRI membranous urethra length had significant impact on post-op urinary continence. • MRI measurements of the urethra length are facile with good inter-rater agreement. • Radiologists should offer this valuable indicator to optimize individual therapy. - Abstract: Purpose: To evaluate standardized measurements of the membranous urethra length (MUL), the membranous urethra angle (MUA) and the prostate's apex type (AT) among further clinical parameters as potential preoperative risk factors of urinary incontinence (UI) after radical prostatectomy (RP).
