Objective:
To investigate the effect of modified Vattikuti Institute prostatectomy (mVIP) in the treatment of localized PCa.
Methods:
This retrospective study included 50 cases of localized PCa treated by mVIP and another 50 by robot-assisted radical prostatectomy (RARP) from March 2018 to April 2019. We analyzed the baseline data, the surgical techniques used and the results of short-term follow-up.
Results:
All the operations were completed successfully without conversion to open surgery. The mVIP group, compared with the RARP, showed longer operation time ([90.35 ± 24.22] vs [84.46 ± 19.18] min, P > 0.05), more intraoperative blood loss ([220.00 ± 15.10] vs [215.00 ± 15.10] ml, P > 0.05), shorter postoperative hospital stay ([5.75 ± 1.45] vs [6.20 ± 1.50] d, P > 0.05), and higher rates of positive surgical margins (22.00% vs 14.00%, P > 0.05) and urinary continence at 1 month (76%vs 22%,P < 0.05), 6 months (84% vs 79%, P > 0.05) and 12 months after surgery (96% vs 94%, P > 0.05).
Conclusions:
Modified VIP can better preserve the lateral and posterolateral prostatic fascial tissue in the treatment of localized PCa and therefore significantly promote the recovery of urinary continence after surgery.
