Abstract: Objective To evaluate the effect of the "Sandwich" reconstruction of the urethrovesical anastomosis contributes to early continence in laparoscopic radical prostatectomy for high-risk prostate cancer. Methods From January 2011 through September 2015, 71 high-risk prostate cancer patients were involved in the study, of whom 47 patients underwent laparoscopic radical prostatectomy with the "Sandwich" reconstruction of the urethrovesical anastomosis and 24 patients underwent laparoscopic radical prostatectomy with standard urethrovesical anastomosis. Outcome data including patient age, body mass index, prostate volume, preoperative prostate specific antigen, Gleason score, clinical stage, operation time, removal of drainage tube's time, removal of catheter time, pathologic stage, lymph node dissection rate, positive surgical margins rate and urinary continence were assessed at 2, 4, 12, 24 and 52 weeks after catheter removal.Results No significant differences were found between the two groups in terms of patient age, body mass index, prostate volume, preoperative prostate specific antigen, Gleason score, clinical stage, removal of drainage tube time, lymph node dissection rate and positive surgical margins rate; The operation time of "Sandwich" reconstruction of the urethrovesical anastomosis was longer than the time of standard urethrovesical anastomosis (P=0.024). A significant difference in removal of catheter time was recorded between the two groups [(14.35±1.83) d in "Sandwich" reconstruction of the urethrovesical anastomosis vs (6.53±0.85)d in standard urethrovesical anastomosis (P <0.001)]; A significant difference of urinary continence was also recorded between the groups (50% in standard urethrovesical anastomosis vs 76.6% in "Sandwich" reconstruction of the urethrovesical anastomosis, P=0.023) after 12 weeks. Conclusion "Sandwich" reconstruction technique in the procedure of urethrovesical anastomosis during laparoscopic radical prostatectomy is safe and feasible, which can improve early recovery of continence for high-risk prostate cancer significantly.
