The ligation of dorsal venous complex (DVC) is a very important procedure during laparoscopic radical prostatectomy (LRP). Inaccurate DVC ligation may lead to severe bleeding or postoperative incontinence. We, therefore, designed the DVC pretightening technique to facilitate this procedure. The 32 involved patients with localized prostate cancer underwent LRP between July 2017 and October 2018. All of the patients received DVC pretightening technique. A laparoscopic intestinal clamp was used to narrow and strain DVC. The needle passage was limited between the bone and clamp. The ligation time, DVC-related blood loss, and continence data were recorded. The ligation of DVC in 32 patients was performed with DVC pretightening technique. Every suture was completed with one attempt. The mean ligation time was 2.7 ± 1.0 min. The DVC-related blood loss was 2.0 ± 1.3 ml. The 3-month continence rate was 81.3% (26/32). Positive margin rate was 9.4% (3/32). In conclusion, the DVC pretightening technique simplified the ligation of DVC during LRP. It is a safe and reliable technique. However, large-sample randomized controlled trials are still required to confirm the advantage of the new method in improving mean ligation time, DVC-related blood loss, continence rate, and positive margin rate.
