Objective To investigate the clinical efficacy and mechanical mechanism of three autologous tissue pelvic floor reconstruction techniques, namely cross suture, sacral ligament suspension, and circular ligament suspension, for the treatment of pelvic organ prolapse (POP). Methods 63 POP patients from 2021 to 2024 were selected and divided into three groups for corresponding surgical procedures. Surgical indicators, recurrence rates, and pelvic floor mechanics indicators were compared. Results There was no statistically significant difference in the incidence of postoperative complications among the three groups (P>0.05); The postoperative indwelling time and hospitalization time of Group A were lower than those of Group B and Group C, and the difference was statistically significant (P<0.05); The intraoperative bleeding in group A was higher than that in groups B and C, and the difference was statistically significant (P<0.05); There was no statistically significant difference in the recurrence rate among the three groups at 1 and 3 months after surgery (P>0.05); The recurrence rate of Group A was lower than that of Group B and Group C at 6 and 12 months after surgery, while the recurrence rate of Group B was higher than that of Group C, P＜0.05； The difference was statistically significant (P<0.05); At 12 months after surgery, Group A had the lowest recurrence rate (4.76%), while Group B had the highest recurrence rate (14.29%); Six months after surgery, the hand measured pelvic floor muscle strength grading, pelvic floor muscle sustained systolic pressure, and maximum vaginal pressure in Group A were higher than those in Group B and Group C. Six months after surgery, ultrasound in Group A showed that the vaginal apex was located at the reference line higher than that in Group BC, while the anal sphincter hiatus area and circumference were smaller than those in Group BC. The difference was statistically significant (P<0.05); The hand measured pelvic floor muscle strength grading and pelvic floor muscle sustained systolic pressure in Group A were higher than those in Group B, and the difference was statistically significant (P<0.05). Conclusion Cross suturing has good clinical efficacy, strong mechanical support, and can be prioritized for promotion.
