LeFort partial colpocleisis is an important surgical procedure for the elderly patients with severe pelvic organ prolapse（POP）who are infirm，have poor ability to tolerate surgery and do not require the preservation of sexual function.The operation is simple，safe and economical，and has unique advantages and indispensable status. This classic operation has a certain recurrence rate and complications such as de novo urinary incontinence after surgery. WANG Wu-liang's team made technical improvements in view of the problems existing in LeFort surgery，and innovatively applied the modified LeFort partial colpocleisis based on the reinforcement of pubocervical fascia and rectovaginal fascia，which had high subjective and objective cure rates and fewer complications and was worth recommending.
