Aim To compare the functional outcomes after laparoscopic radical prostatectomy (LRP) and robot-assisted laparoscopic radical prostatectomy (RARP). Methods Between September 2008 and January 2016, 712 patients underwent radical prostatectomy (RP; 614 LRP and 98 RARP). Recovery of incontinence was evaluated through a 24-h pad test. Urinary and erectile function was evaluated using the International Prostate Symptom Score (IPSS) and the International Index of Erectile Function-5. Follow-up interval was 1, 3, 6 and 12 months after the surgery. The propensity score matching was used to balance the preoperative characteristics. Results The recovery of incontinence was similar to the two groups at 6 and 12 months after the surgery. However, patients underwent RARP restored the continence sooner than those in the LRP group in 1 and 3 months after the surgery (P < 0.001 and 0.001). For the multivariable analysis, the type of RP procedure was a uniquely meaningful contributing factor (P = 0.001, HR = 1.925; 95% CI, 1.299–2.851). In the case of urinary function, the RARP groups showed a better IPSS score than LRP groups at the 1-, 3- and 6-month visits, respectively (P = 0.008, 0.026, 0.001), and the RARP groups early improved compared with LRP groups at the 3-month visit in the case of erectile function (P = 0.018). Conclusion The RARP tended toward getting back the urinary continence earlier than the LRP. In addition, urinary and erectile function recovered more quickly in the RARP group than in the LRP group.

AIMS To assess the accuracy of multiparametric magnetic resonance imaging (mpMRI), used in conjunction with the Prostrate Imaging Reporting and Data System (PI-RADS), version 2, in the detection of prostate cancer (PCa), and to determine the extent of the efficacy of mpMRI as a screening test in biopsy-naive patients. METHODS Retrospective analysis was conducted in 107 patients who underwent mpMRI prior to radical prostatectomy (RP) at a single institution. The mpMRI findings were reassessed using PI-RADS, version 2. A comparison was made between the histological findings for the RP specimens and the mpMRI results. RESULTS Unique histologically confirmed PCa foci (237) were identified in 107 patients. Overall, mpMRI sensitivity of 46% was found for PCa detection (110/237). The sensitivity, specificity and negative predictive value of mpMRI was 75.5%, 77.0% and 79.8%, respectively, for clinically significant cancer, and 75.7%, 77.7% and 79.5%, for pathological index tumors. A moderate and significant correlation was observed between a high PI-RADS score and a high pathological grade, tumor volume, index tumor status and clinically significant cancer status (all, P
