To present own initial experience of Retzius-sparing robot-assisted radical prostatectomy (RS-RARP) and surgical technique. In OctoberNovember 2019 on the basis of the Urological Department and the Center for Robotic Surgery of City Mariinsky Hospital (Saint Petersburg, Russia) five patients with localized prostate cancer were treated with RS-RARP. The operation time was from 140 to 205 min. The blood loss volume was from 50 to 250 ml. No conversions and intraoperative complications were recorded. Nervous-saving RS-RARP was performed in three patients. No blood transfusions were performed. Two patients faced Clavien Grade I postoperative complications. Immediate continence after removal of the urethral catheter was noted in 3 out of 5 patients. All the patients became continent for 2 weeks. One extraprostatic positive surgical margin was recorded. RS-RARPis an accessible technique for treating patients with localized prostate cancer, which allows achieving high early results. It is necessary to accumulate more experience of such surgeries to assess the distant outcomes and compare them with the data of the robot-assisted radical prostatectomies performed by other approaches.

AbstractThe positive surgical margin (PSM) and biochemical recurrence (BCR) are two main factors associated with poor oncotherapeutic outcomes after prostatectomy. This is an Asian population study based on a single-surgeon experience to deeply investigate the predictors for PSM and BCR. We retrospectively included 419 robot-assisted radical prostatectomy cases. The number of PSM cases was 126 (30.1%), stratified as 22 (12.2%) in stage T2 and 103 (43.6%) in stage T3. Preoperative prostate-specific antigen (PSA) > 10 ng/mL (p = 0.047; odds ratio [OR] 1.712), intraoperative blood loss > 200 mL (p = 0.006; OR 4.01), and postoperative pT3 stage (p < 0.001; OR 6.901) were three independent predictors for PSM while PSA > 10 ng/mL (p < 0.015; hazard ratio [HR] 1.8), pT3 stage (p = 0.012; HR 2.264), International Society of Urological Pathology (ISUP) grade > 3 (p = 0.02; HR 1.964), and PSM (p = 0.027; HR 1.725) were four significant predictors for BCR in multivariable analysis. PSMs occurred mostly in the posterolateral regions (73.8%) which were associated with nerve-sparing procedures (p = 0.012) while apical PSMs were correlated intraoperative bleeding (p < 0.001). A high ratio of pT3 stage after RARP in our Asian population-based might surpass the influence of PSM on BCR. PSM was less significant than PSA and ISUP grade for predicting PSA recurrence in pT3 disease. Among PSM cases, unifocal and multifocal positive margins had a similar ratio of the BCR rate (p = 0.172) but ISUP grade > 3 (p = 0.002; HR 2.689) was a significant BCR predictor. These results indicate that PSA and pathological status are key factors influencing PSM and BCR.
