Background: Robot-assisted radical prostatectomy (RARP) is a widespread option for the treatment of patients with clinically localised prostate cancer. Modifications in the surgical technique may help to further improve functional outcomes., Objective: To assess the outcome of early catheter removal 48h after surgery, as opposed to standard catheter removal 6 d after surgery following RARP, using a newly developed surgical technique for posterior reconstruction and anastomosis (Aalst technique)., Design, Setting, and Participants: Patients scheduled for RARP were prospectively scheduled for early catheter removal at postoperative d 2 (group A, n=37) and standard catheter removal at postoperative d 6 (group B, n=37)., Surgical Procedure: RARP was performed using the Da Vinci Si system. The Aalst technique for the urethro-vesical anastomosis including posterior reconstruction was used as previously described., Outcome Measurements and Statistical Analysis: The primary endpoint was spontaneous voiding after catheter removal. Secondary endpoints were rate of anastomotic urinary leakage after catheter removal, presence and severity of urethral, perineal, and abdominal pain, as well as patient's bother after catheter removal using visual analogue scale (VAS) scores. Rate and severity of urinary incontinence after catheter removal were assessed using the International Consultation on Incontinence Questionnaire-Male Lower Urinary Tract Symptoms Module (ICIQ-MLUTS) questionnaire., Results and Limitations: There was no significant difference between the groups with regard to baseline and perioperative parameters, as well as pathological features; however, significantly more patients underwent bilateral nerve-sparing procedures in group A (34 vs 23, p=0.008). After catheter removal, patients in both groups showed spontaneous voiding, whereas only 11% and 8% of the patients in group A and group B experienced urinary retention after catheter removal (p=0.7). Patients in group B had significantly higher maximum flow rates, but lower voided volumes after catheter removal in comparison with patients in group A (21ml/s vs 10ml/s, p≤0.001 and 170ml vs 200ml, p≤0.001, respectively). ICIQ-MLUTS questionnaire and VAS scores showed no significant differences between the groups at any time point., Conclusions: The Aalst technique allows the removal of catheters 2 d after RARP and results in spontaneous voiding. Early removal showed no increased rate of urinary leakage, no negative impact on short-term continence and on perineal, urethral or penile pain, and no increase in urinary retention rates. Future studies have to confirm these results with longer follow-up including detailed parameters on return to daily activity., Patient Summary: We provide evidence that it is possible to remove the bladder catheter as early as 2 d after robot-assisted radical prostatectomy without any negative effects on voiding and pain parameters. Thus, leaving the hospital early without a catheter in place could represent a significant and relevant benefit for the patient., (Copyright © 2015 European Association of Urology.

Background: The introduction of robotics revolutionized prostate cancer surgery because the magnified three-dimensional vision system and wristed instruments allow microsurgery to be performed. The advantages of robotic surgery could lead to improved continence outcomes in terms of early recovery compared with the traditional surgical methods., Objective: To describe the total anatomical reconstruction (TAR) technique during robot-assisted radical prostatectomy (RARP)., Primary Endpoint: evaluation of the continence rate at different time points. Secondary endpoint: evaluation of urine leakage and anastomosis stenosis rates related to the technique., Design, Setting, and Participants: June, 2013 to November, 2014; prospective consecutive series of patients with localized prostate cancer (cT1-3, cN0, cM0)., Surgical Procedure: RARP with TAR was performed in all cases. Lymph node dissection was performed if the risk of lymph nodal metastasis was over 5%, according to the Briganti updated nomogram., Measurements: Preoperative, intraoperative, postoperative, and pathological variables were analyzed. Enrolled patients were arbitrarily divided into three groups according to a time criterion. The relationships between the learning curve and the trend of the above-mentioned variables were analyzed using LOESS analysis. Continence was rigorously analyzed preoperatively and at 24h, 1 wk, 4 wk, 12 wk, and 24 wk after catheter removal., Results and Limitations: In total, 252 patients were analyzed. The continence rates immediately after catheter removal and at 1 wk, 4 wk, 12 wk, and 24 wk after RARP were 71.8%, 77.8%, 89.3%, 94.4%, and 98.0%, respectively. Multivariate analysis revealed that the nerve sparing technique, D'Amico risk groups, lymph node dissection, and prostate volume were involved in the early recovery of urinary continence. One ileal perforation requiring reoperation was recorded. The transfusion rate was 0.8%. Thirty-one (12.3%) postoperative complications were recorded up to 6 mo after surgery. Among these, eight acute urinary retentions (3.2%) and three urine leakages (1.2%) were recorded. There was a lack of randomization and comparison with other techniques. Both anatomical dissection of the prostatic apex and TAR were used. The results may not be generalized to low-volume centers., Conclusions: The TAR technique showed promising results in the early recovery of urinary continence, as well as watertight anastomosis and a low rate of urine leakage. The oncologic results were not affected. Comparative studies are needed to support the quality of reported results., Patient Summary: On the basis of our findings, it seems that the risk of urinary incontinence following radical prostatectomy can be lowered via meticulous anatomical reconstruction using a robotic system. Comparative studies are required to support the reported results., (Copyright © 2015 European Association of Urology. Published by Elsevier B.V. All rights reserved.)
