Abstract:
OBJECTIVE:To evaluate the impact of sutureless approach to the dorsal venous complex (DVC) combined with robotic-assisted laparoscopic prostatectomy on sexual function of patients with prostatic cancer.
METHODS:This study included 114 prostate cancer patients who underwent robot-assisted laparoscopic radical prostatectomy at our hospital from January 2021 to January 2024. The patients were randomly divided into a control group (n=57) and an observation group (n=57). The control group received conventional "figure-of-eight" suture ligation of the dorsal venous complex (DVC), while the observation group underwent direct DVC transection using monopolar electrocautery scissors after increasing pneumoperitoneum pressure.Surgical duration, intraoperative blood loss, positive surgical margin rates, and positive apical margin rates were recorded. The continence rates and rates of morning erections at 1, 3 and 6 months after the operation were compared between groups. Sexual function was assessed pre-operatively and at 6 months post-operation by using the IIEF-5 and PEDT.
RESULTS:The operative time in the observation group was significantly longer than that in the control group (［115.71 ± 19.42］ min vs ［103.42 ± 12.78］ min， P<0.05). While no significant differences were observed in intraoperative blood loss, positive surgical margin rate, or positive apical margin rate between the two groups (P>0.05). At 3 and 6 months after the operation, the observation group exhibited higher urinary continence rates and morning erection recovery rates compared to the control group （P<0.05). Furthermore, at 6 months postoperatively, the observation group demonstrated significantly higher IIEF-5 scores and lower PEDT scores than those of control group(P<0.05).
CONCLUSION:The use of a sutureless DVC technique in robotic-assisted laparoscopic radical prostatectomy protects the post-operative sexual function in patients.
