Long-term functional outcomes of vesicourethral anastomosis with bladder neck preservation and distal urethral length preservation after videolaparoscopic radical prostatectomy

Radical prostatectomy (RP) is the standard surgical treatment for localized prostate cancer (PCa), with excellent oncologic outcomes; however, complications such as post-prostatectomy incontinence could significantly affect quality of life. To provide data on long-term urinary functional outcomes of bladder neck preservation (BNP) combined with distal urethral length preservation (DULP) in patients treated with videolaparoscopic prostatectomy. In this retrospective study, data were analysed from 619 consecutive patients who underwent laparoscopic radical prostatectomy (LRP) due to localized prostate cancer between November 2014 and December 2018 in a single tertiary care centre in Poland. Of these patients, 227 had BNP and DULP during the procedure. Urinary continence status was assessed in patients at 3, 6, 12, and 18 months after LRP. Cancer resection was assessed by surgical margin status. In the group with BNP and DULP, urinary continence recurred earlier than it did in the control group up to 3 months after surgery: 204 (89.8%) patients in this group were fully continent compared with 283 (72.2%) in the control group (p < 0.001). The difference was also significant after 6 months (95.1% vs. 80.6%, respectively; p < 0.001). Despite these early promising results, there was no difference in urinary continence recovery after 12 and 18 months. There was also no difference between the 2 groups regarding surgical margin status of the resected tissue. Our study showed that BNP combined with DULP is a safe procedure that helps to improve early urinary continence rates after surgery without altering the risk of positive surgical margin
