Study summary

This study is a multicenter, prospective cohort study. The main purpose of the study is to construct diagnostic model for vaginal laxity.

Read the detailed description

The main purpose of the study is to construct diagnostic model for vaginal laxity based on multimodal clinical data. Besides, for the enrolled patients, we conducted follow-up for those whose vaginas could accommodate more than two fingers. According to the treatment methods they received, they were divided into three groups: Patients in Group 1 underwent pelvic floor muscle exercises, those in Group 2 received physical therapy, and those in Group 3 underwent surgical treatment. This grouping is based on clinical routine diagnosis and treatment opinions. It only observes the improvement effect of vaginal relaxation in patients of different groups and does not conduct any additional interventions on the patients. Therefore, this study is an observational study.

Study population

Female patients who visited the gynecology outpatient department of the participating project hospital from September 2026 to September 2027.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Women over the age of 18 who have sex
  2. Understand and voluntarily sign the written form.

Exclusion criteria

Exclusion Criteria:

  1. Gynecological examination confirmed the presence of stage III or above pelvic organ prolapse
  2. There is cognitive impairment, unable to understand the content of the questionnaire or cooperate to complete the transvaginal ultrasound examination
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Groups and cohorts

  • Group 1: Pelvic floor muscle training

    For patients whose vaginas can accommodate more than two fingers, if they undergo pelvic floor muscle exercises, they will be assigned to Group 1.

    Behavioral: Pelvic floor muscle training

  • Group 2: physical therapy

    For patients whose vaginas can accommodate more than two fingers, if they receive physical therapy, including laser, radiofrequency, and biofeedback, they will be classified into Group 2.

    Other: Physical treatment

  • Group 3: Surgery

    For patients whose vaginas can accommodate more than two fingers, if they receive surgeries, they will be classified into Group 3.

What researchers measure

Primary outcomes

  1. Construction of diagnostic model for vaginal laxity

    Integrating multi-model indicators to construct gold standard diagnostic model for vaginal laxity, including age (year), weight (kg), height (m), gravidity, parity, vaginal tactile imaging, pelvic floor ultrasound, POP-Q points, modified oxford muscle strength, female sex function index (FSFI), International Consultation on Incontinence Questionnaire (ICIQ), Pelvic Floor Distress Inventory-20(PFDI-20) and Overactive bladder symptom score (OABSS)

    Time frame: From enrollment to the end of treatment at 12 months

Secondary outcomes

  1. Severity of overactive bladder

    Overactive bladder symptom score (OABSS) questionnaire will be used to assess the severity of overactive bladder

    Time frame: From enrollment to the end of treatment at 12 months

  2. Sex function

    Female sex function index (FSFI) questionnaire will be used to assess sex function

    Time frame: From enrollment to the end of treatment at 12 months

  3. Severity of pelvic floor dysfunction

    Pelvic Floor Distress Inventory-20 (PFDI-20) questionnaire will be used to assess severity of pelvic floor dysfunction

    Time frame: From enrollment to the end of treatment at 12 months

  4. Severity of lower urinary tract symptom

    International Consultation on Incontinence Questionnaire (ICIQ) will be used to assess severity of lower urinary tract symptom

    Time frame: From enrollment to the end of treatment at 12 months

  5. Subjective degree of vaginal laxity

    The vaginal laxity questionnaire (VLQ) will be used to assess subjective degree of vaginal laxity

    Time frame: From enrollment to the end of treatment at 12 months

  6. Sexual satisfaction

    The sexual satisfaction questionnaire (SSQ) will be used to assess sexual satisfaction

    Time frame: From enrollment to the end of treatment at 12 months

  7. Patients' satisfaction for the treatment

    Patient Global Impression of Improvement (PGI-I) will be used to assess patients' satisfaction for the treatment.

    Time frame: From enrollment to the end of treatment at 12 months

  8. Severity of pain

    Visual Analogue Scale (VAS) will be used to assess the severity of pain

    Time frame: From enrollment to the end of treatment at 12 months

  9. Urodynamic test

    Urodynamic tests were performed for free uroflowmetry, post-void residual urine volume, and cystometry in the sitting position. In free uroflowmetry, the maximum flow rate (Qmax), average flow rate (Qave), and flow time were recorded, while bladder volumes were measured during the filling cystometry test at the patient's first sense, first desire, and strong desire for urination. Besides, we paid attention to whether detrusor overactivity (DO) was noted during filling cystometry. The detrusor pressure at maximum flow (PdetQmax) and the maximum urethral closure pressure (MUCP) were also measured

    Time frame: From enrollment to the end of treatment at 12 months

  10. Pelvic floor ultrasound

    Bladder neck position, uterine descent, bladder neck descent, cervical position, retrovesical angle, rectal ampulla descent, bladder neck opening, urethral rotation angle, levator hiatus area, anorectal angle (ARA), puborectalis muscle integrity, perineal body thickness, perineal body length will be recorded.

    Time frame: From enrollment to the end of treatment at 12 months

  11. Vaginal tactile imaging

    The images from the vaginal tactile imaging will be collected.

    Time frame: From enrollment to the end of treatment at 12 months

  12. Maximum vaginal capacity index

    Time frame: From enrollment to the end of treatment at 12 months

  13. Modified oxford muscle strength

    Time frame: From enrollment to the end of treatment at 12 months

  14. Pelvic organ prolapse quantification (POP-Q)

    Time frame: From enrollment to the end of treatment at 12 months

Other outcomes

  1. Safety of surgery

    The following relevant data will be collected: the duration of the surgery, the amount of bleeding, the changes in hemoglobin levels before and after the surgery, the length of hospital stay, whether there was any intraoperative organ damage, and postoperative urinary retention.

    Time frame: From enrollment to the end of treatment at 12 months

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
