Study summary

Enrolled patients with urinary incontinence in Peking University People's Hospital, Wuhan People's Hospital, Zhongshan People's Hospital, and Jiangsu Maternity and Child Health Hospital in the Department of Gynecology, and collected baseline data. The random number table was used to divide the period into observation group and control group. The observation group was treated with a new type of pelvic floor rehabilitation therapy device PHENIX U4+, and the control group was treated with a traditional pelvic floor electrical stimulation therapy device. Follow-up observations during the treatment period and at the end of the treatment, 3 months and 6 months, the main follow-up content includes 1h pad test, 72-hour urination diary, modified Oxford muscle strength classification diagnosis, urinary incontinence-related questionnaires, new equipment inspections, etc. , Track and compare the treatment effect.

Read the detailed description

Use two pelvic floor treatment devices to treat urinary incontinence, collect relevant questionnaires and pelvic floor muscle strength, and compare the two treatment devices.

Study arms

  • Experimental
    PHENIX U4+

    Electrical stimulation treatment for patients with urinary incontinence using a new type of pelvic floor therapy instrument

    Device: PHENIX U4+

  • Active comparator
    Traditional pelvic floor electrical stimulation therapy instrument

    Electrical stimulation treatment for patients with urinary incontinence using traditional pelvic floor therapy instrument

    Device: Traditional pelvic floor treatment instrument

Interventions

  • DevicePHENIX U4+

    The newly developed domestic PHENIX U4+ is relatively small in size. In addition to the smooth muscle stimulation function of the traditional therapy device, its electrical stimulation waveform setting can also stimulate the striated muscle, and adds more than 10 A3 reflex treatment options, which can inhibit Urinary reflex, resulting in symptoms related to urinary incontinence in the patient.

  • DeviceTraditional pelvic floor treatment instrument

    Traditional pelvic floor treatment instrument commonly used in clinical practice

What researchers measure

Primary outcomes

  1. The difference in the effective rate of urinary incontinence treatment between the two groups

    The effective rate of urinary incontinence treatment is judged by whether it leaks urine or not

    Time frame: Before treatment, immediately after treatment, three months after treatment, and six months after treatment

Secondary outcomes

  1. Differences in pelvic floor electromyography between the two groups

    Time frame: Before treatment, immediately after treatment, three months after treatment, and six months after treatment

  2. Differences in 72-hour urination diary

    reflect urination of 72 hours

    Time frame: Before treatment, immediately after treatment, three months after treatment, and six months after treatment

  3. Person coefficient of correlation between results of gynecological examination and new equipment examination

    Time frame: Before treatment, immediately after treatment, three months after treatment, and six months after treatment

  4. Differences in questionnaire score: PFDI-20

    Questionnaires reflecting pelvic floor function, lower urinary tract symptoms, and quality of life

    Time frame: Before treatment, immediately after treatment, three months after treatment, and six months after treatment

  5. Differences in questionnaire score: ICI-Q-SF

    Questionnaires reflecting lower urinary tract symptoms

    Time frame: Before treatment, immediately after treatment, three months after treatment, and six months after treatment

  6. Differences in questionnaire score: OABSS

    Questionnaires reflecting lower urinary tract symptoms

    Time frame: Before treatment, immediately after treatment, three months after treatment, and six months after treatment

  7. Differences in questionnaire score: UDI-6

    Questionnaires reflecting lower urinary tract symptoms, and quality of life

    Time frame: Before treatment, immediately after treatment, three months after treatment, and six months after treatment

  8. Differences in pelvic floor pressure test between the two groups

    Time frame: Before treatment, immediately after treatment, three months after treatment, and six months after treatment

  9. Differences in pelvic floor tension test between the two groups

    Time frame: Before treatment, immediately after treatment, three months after treatment, and six months after treatment
