: Radical hysterectomy has a profound effect on pelvic floor function and the quality of life of patients with cervical cancer. How to maximize the retention of sexual function and prevent pelvic floor dysfunction remains an issue worth discussing. Currently, the main prophylactic surgical treatment usually refers to the hysterosacral ligament suspension during benign hysterectomy, but there is a lack of research on how to prevent pelvic organ prolapse during radical hysterectomy. Peking Union Medical College Hospital performed the first such preservation surgery by applying an ischial spinous fascia fixation suture technique to suspend the vagina arch on the ischial spinous fascia. We present a surgical technique for ischial spinous fascia fixation in the laparoscopic radical hysterectomy. This surgery can reduce the incidence of vaginal wall prolapse as it is safe and feasible to suspend the vagina stump because the ischial spine fascia is dense and devoid of important blood vessels and nerves. The use of tissue-autografting helps to relieve prolapse symptoms and restore pelvic anatomy, hence maintaining the patient’s sexual function. The prognosis of early cervical cancer is generally good. It is helpful to understand the incidence of pelvic floor dysfunction after cervical cancer surgery and to take targeted surgical preventive measures during the operation to improve the quality of life of patients.

Ischial spinous fascia fixation is worthy of further promotion and validation.
