To investigate the effect of negative pressure treatment combined with pelvic floor muscle training on urinary continence and sexual function of patients with prostate cancer (PCa) after radical prostatectomy.

From October 2016 to April 2019, in the Third Affiliated Hospital of Sun Yat-sen University 70 patients were diagnosed with prostate cancer and underwent laparoscopic radical prostatectomy. According to the random number table method, they were divided into intervention group and control group, 35 cases each. The control group of 35 patients received routine nursing (pelvic floor muscle functional exercise), and the intervention group of 35 patients underwent routine nursing, and then increased negative pressure exercise therapy from six weeks after surgery. The urinary continence were compared at 6 weeks, 10 weeks, and 18 weeks. At the same time, the International Erectile Function Scale (IIEF-5) score and subjective well-being survey were conducted to observe the treatment effect.

The median scores of urinary incontinence at 6 weeks, 10 weeks, and 18 weeks in the intervention group were 2, 1 and 0, respectively, which were significantly lower than those in the control group. The recovery time of urinary control function was shorter than that of the control group, and the difference was statistically significant (P<0.05); In addition, the intervention group had a faster increase in IIEF-5 score and subjective well-being score than the control group, suggesting that the intervention group had postoperative erectile function. The improvement of the quality of life was significantly better than the control group.

Negative pressure therapy combined with pelvic floor muscle training can significantly improve the urinary continence and sexual function of patients after radical prostatectomy, shorten their recovery time.
