Abstract：Objective：To observe the clinical effect of the combination use of thunder-fire moxibustion and pelvic floor biofeedback electric stimulation therapy on urinary incontinence after surgery of prostatic hyperplasia and its effect on urodynamic parameters. Methods： A total of 100 patients with urinary incontinence after surgery of prostatic hyperplasia admitted to Wenzhou TCM Hospital of Zhejiang Chinese Medical University from July 2023 to July 2024 were selected and divided into the control group and the observation group according to the random number table method，with 50 cases in each group. The control group was treated with comparative pelvic floor biofeedback electrical stimulation， and the observation group was treated with thunder-fire moxibustion combined with pelvic floor biofeedback electrical stimulation. Both groups were treated for eight weeks. The clinical effects， and the scores of International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form （ICI-Q-SF） and Incontinence Quality of Life Questionnaire （I-QOL）， pelvic floor muscle function indexes [maximum contractility， continuous contractility and resting electromyography]，and urodynamic parameters [maximum urinary flow rate （Qmax）， bladder compliance （BC） and residual urine volume （RUV） ] before and after treatment were compared between the two groups. Results： After treatment， the total effective rate was 96.00% （48/50） in the observation group and 84.00% （42/50） in the control group， with a statistically significant difference （P＜0.05） . After treatment， the ICI-Q-SF scores in the two groups were reduced when compared with those before treatment （P＜0.05）， and the ICI-Q-SF score in the observation group was lower than that in the control group （P＜0.05） . The I-QOL scores in the two groups were higher than those before treatment （P＜0.05）， and the I-QOL score in the observation group was higher than that in the control group （P＜0.05） . After treatment，the maximum and continuous contractility of pelvic floor muscle in the two groups were elevated when compared with those before treatment （P＜0.05），and the maximum and continuous contractility of pelvic floor muscle in the observation group were higher than those in the control group （P＜0.05） . The resting electromyography of pelvic floor in the two groups was lower than that before treatment （P＜0.05），and the resting electromyography of pelvic floor in the observation group was lower than that in the control group （P＜0.05） . After treatment， the levels of Qmax and BC in the two groups were higher than those before treatment （P＜0.05），and the above two levels in the observation group were higher than those in the control group （P＜0.05） . The RUV levels in the two groups dwindled when compared with those before treatment （P＜ 0.05），and the RUV level in the observation group was lower than that in the control group （P＜0.05） .Conclusion： The combination use of thunder-fire moxibustion and pelvic floor biofeedback electric stimulation can improve the urination and urodynamic parameters of patients with urinary incontinence after surgery of prostatic hyperplasia， effectively promote the recovery of pelvic floor muscle function，and thus improve the quality of life.
