[Modified Vattikuti Institute prostatectomy for the treatment of localized prostate cancer].

ABSTRACT

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 (ï¼»90.35 ± 24.22ï¼½ vs ï¼»84.46 ± 19.18ï¼½ min, P > 0.05), more intraoperative blood loss (ï¼»220.00 ± 15.10ï¼½ vs ï¼»215.00 ± 15.10ï¼½ ml, P > 0.05), shorter postoperative hospital stay (ï¼»5.75 ± 1.45ï¼½ vs ï¼»6.20 ± 1.50ï¼½ 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.
