Pelvic organ prolapse is a common problem. The primary treatment is surgery. Ischia spinous fascia fixation procedure is developed in China for vaginal apex fixation with native tissue.

This study is designed to determine the effectiveness and safety of ischia spinous fascia fixation procedure for the treatment of pelvic organ prolapse stage III.

Patients enrolled into the study will be followed up for up to 3 years after surgery. Evaluation will take place during surgery and postoperative visit. Stage of prolapse before and after surgery, patient satisfaction through quality of life and sexual function questionnaires before and after surgery, and peri-operative complication rates will be evaluated.

Pelvic Organ prolapse (a feeling of bulge in the vagina) may cause some distressing symptoms such as loss of control of the bowel or bladder, and may also cause problems with patient's sex life. An ideal procedure for vaginal apical support should provide a durable suspension, have minimal complications, and not affect sexual or visceral function.

Ischia spinous fascia fixation procedure is developed in China. It is a transvaginal procedure used for restoring the vaginal apex support with native tissue. Clinical practice showed that it was safe, efficient and cost-effective. Recurrent rate after 1 year follow-up was about 10%, and quality of life improved significantly from the baseline.

The purpose of this multicenter, prospective study is to evaluate the effectiveness and safety of this procedure in the treatment of symptomatic pelvic organ prolapse.

Inclusion Criteria:

• Candidates with symptomatic pelvic organ prolapse of POP-Q Stage II or more, suitable for surgical repair.
• Vaginal hysterectomy and anti-incontinence procedures could be performed concurrently.
• Agrees to participate in the study, including completion of all study-related procedures, evaluations and questionnaires.

Exclusion Criteria:

• Previous repair of pelvic organ prolapse involving insertion of mesh.
• Experimental drug or experimental medical device within 3 months prior to the planned procedure.

• Coagulation disorder or on therapeutic anticoagulant therapy at the time of surgery.
• History of chemotherapy or pelvic radiation therapy.
• Systemic disease known to affect bladder or bowel function (e.g. Parkinson's disease, multiple sclerosis, spinal cord injury or trauma).
