The position of urethrovesical anastomosis after robotic radical prostatectomy assessed by MRI predicts early functional recovery: A cohort analyses from a randomized clinical trial

•MRI measurements to determine anastomosis positioning after radical prostatectomy are reliable and have a strong correlation between readers.•The final positioning of the uretrovesical anastomosis varies according to the type of reconstruction after radical prostatectomy.•The final positioning of the anstomosis is related to early urinary recovery: MRI parameters are independent predictors of urinary continence. Functional and anatomical changes associated with prostate removal coincide with alterations in pelvic structures. Posterior rhabdosphincter reconstruction was designed to improve urinary continence after radical prostatectomy. The aim of this study was to determine magnetic resonance anatomic predictors of urinary recovery after radical prostatectomy, and to assess their relation to the type of reconstruction. Forty patients were randomly selected from a trial (NCT03302169). Two independent radiologists determined the situation of the anastomosis in the pelvis according to MRI performed a month after the radical prostatectomy: vertical situation assessed as the distance to the line coccyx-inferior pubic margin (ACPv) and anteroposterior situation as the distance from the pubis (Distance A), and from the coccyx (Distance B). The Pearson correlation of ACPv, Distance A, and B between readers were 0.975, 0.940, and 0.711, p
