Clinical study of ischia spinous fascia fixation--a new pelvic reconstructive surgery.

INTRODUCTION AND HYPOTHESIS: This study aims to introduce a new pelvic reconstructive procedure and assess its safety and efficacy.

METHODS

Anatomic dissection was performed on ten Chinese female cadavers. The fascia 1 cm horizontally lateral to the ischial spine was firm and strong with no major vessels or nerves in the area. Thirty-two patients with stage III uterine prolapse underwent ischial spinous fascia fixation procedure. Objective and subjective results were observed in follow-up evaluations.

RESULTS

No severe complications were observed. The objective success rate was 94% at 1-year follow-up while two patients (6.3%) showed recurrence. There were significant improvements in Aa, Ba, Ap, Bp, and C (p < 0.001) by pelvic organ prolapse quantification. Two patients suffered from lower back pain and right thigh pain, respectively, while three complained a sensation of a foreign body in the vagina.

CONCLUSION

As a treatment of vaginal fornix prolapse, ischial spinous fascia fixation is found to be safe and efficacious.
