IntroductionPreservation of the bladder neck (BN) has been controversial, as limited excision of the bladder neck may result in incomplete resection of the disease. Moreover, the urinary continence rate may not be improved.AimTo evaluate the effect of bladder neck sparing on urinary continence, and surgical margins status in prostate cancer (PCa) patients treated with laparoscopic radical extraperitoneal prostatectomy.Material and methodsA retrospective analysis of 295 consecutive patients who had undergone laparoscopic radical extraperitoneal prostatectomy for clinically localised prostate cancer in a single institution was performed. Positive surgical margin (SM(+)) and urinary continence status at 3, 6, and 12 months were evaluated.ResultsThe distribution of SM(+) for pT2, pT3, and pT4a was 15.3% (27/176), 49.1% (58/118), and 100% (1/1), respectively. Overall, there were 55.61%, 80.61%, and 84.69% of men continent at 3, 6, and 12 months, respectively. However, when limiting the analysis to those who did not receive adjuvant radiotherapy within 12 months following surgery, urinary continence rates were 59.23%, 85.86%, and 90.21% at 3, 6, and 12 months, respectively. Preoperative prostate-specific antigen (PSA) and pathological T stage were identified as significant predictors of positive surgical margins.ConclusionsConclusions: Laparoscopic radical extraperitoneal prostatectomy with bladder neck preservation has been a safe procedure which has resulted in good functional outcome. We observed a relatively high incidence of positive surgical margins which could be attributed to a large number of extracapsular disease cases.

IntroductionA vesicourethral anastomosis is the most challenging and time-consuming step of radical prostatectomy. In 2003, van Velthoven introduced his own technique of connecting the bladder neck with the membranous urethra, which has remained the most popular method since. Despite being effective, this method is time consuming and is not free from the risk of complications.AimHere we describe our technique for laparoscopic vesicourethral anastomosis using a running suture as an alternative to the traditional approach.Material and methodsThe vesicourethral anastomosis is created using a running stitch placed first at the 5 o'clock position on the posterolateral aspect of the bladder outside-in and then through the urethra at the same location inside-out. Proceeding anticlockwise, the running suture is placed 5 times more through both the bladder neck and the urethra in a similar fashion until it meets the free end at the 5 o'clock position. A single knot is then tied outside the bladder.ResultsThe anastomotic technique has been used in 28 patients with clinically organ confined prostate cancer. The mean anastomosis time was 9.53 min, the mean operative time was 155.20 min, the mean drain permanence was 2.71 days, and the mean catheterisation time was 17.28 days. Continence rate 3 months after surgery was 92.85%, and 100% at 6- and 12-month follow-up visits.ConclusionsWe describe a safe, feasible and efficient technique for vesicourethral anastomosis. Further studies on a larger group of patients are needed to confirm our encouraging preliminary results.
