To test the impact of the prostate-gland asymmetry on continence rates, namely 3- and 12-month continence recovery, in prostate cancer (PCa) patients who underwent robot-assisted radical prostatectomy (RARP). Within our institutional database, RARP patients with complete preoperative MRI features and 12 months follow-up were enrolled (2021-2023). The population has been stratified according to the presence or absence of prostate-gland asymmetry (defined as the presence of median lobe or side lobe dominance). Multivariable logistic regression models (LRMs) predicting the continence rate at 3 and 12 months after RARP were fitted in the overall population. Subsequently, the LRMs were repeated in two subgroup analyses based on prostate size (≤ 40 vs > 40 ml). Overall, 248 consecutive RARP patients were included in the analyses. The rate of continence at 3 and 12 months was 69 and 72%, respectively. After multivariable LRM the bladder neck sparing approach (OR 3.15, 95% CI 1.68-6.09, p value < 0.001) and BMI (OR 0.90, 95% CI 0.82-0.97, p = 0.006) were independent predictors of recovery continence at 3 months. The prostate-gland asymmetry independently predicted lower continence rates at 3 (OR 0.33, 95% CI 0.13-0.83, p = 0.02) and 12 months (OR 0.31, 95% CI 0.10-0.90, p = 0.03) in patients with prostate size ≤ 40 ml. The presence of prostate lobe asymmetry negatively affected the recovery of 3- and 12-months continence in prostate glands ≤ 40 mL. These observations should be considered in the preoperative planning and counseling of RARP patients.
