[Normal- versus negative-pressure drainage after laparoscopic radical prostatectomy in the treatment of prostate cancer].

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 follow-up data on 87 cases of PCa treated by LRP from October 2019 to October 2022, 46 receiving norPD and the other 41 negPD postoperatively. 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 volume ≤30 ml/d. We compared the operation time, intraoperative blood loss, drainage volume on the first day after surgery, total postoperative 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 significant 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 norPD 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.
