상세 설명
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.

Urodynamic test
기간: From enrollment to the end of treatment at 12 months

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 |
