Abstract：Objective:To compare the effects of normal-pressure drainage(norPD)and negative-pressure drainage(negPD)after laparoscopic radical prostatectomy(LRP)in the treatment of PCa.Methods:We retrospectively analyzed the clinical and fol-low-up data on 87 cases of PCa treated by LRP from October 2019 to October 2022,46 receiving norPD and the other 41 negPD postop-eratively.We indwelt an F20 pelvic drainage tube for each of the patients,which were connected to an anti-reflux drainage bag for those in the norPD group and a 200 ml negative pressure ball for those in the negPD group,and removed the tubes at the drainage vol-ume ≤30 ml/d.We compared the operation time,intraoperative blood loss,drainage volume on the first day after surgery,total post-operative drainage volume,drainage tube-indwelling duration,drainage tube-related nursing time,urinary catheter removal time,wound healing time,and incidence of postoperative complications between the two groups of patients.Results:No statistically signif-icant differences were observed between the two groups in terms of operation time,intraoperative blood loss,wound healing time,and postoperative complications(P＞0.05).The drainage volume on the first postoperative day and the total postoperative drainage volume were significantly lower,and the drainage tube-indwelling duration and drainage tube-related nursing time markedly shorter in the nor-PD than in the negPD group(all P＜0.05).Conclusion:Normal-pressure drainage is a safe and effective drainage method after laparoscopic radical prostatectomy,which can significantly reduce the postoperative drainage volume,drainage tube-indwelling duration and drainage tube-related nursing time.
