Abstract：Objective To study the pelvic floor muscle function and the life quality after two kinds of pelvic floor reconstruction:the mesh and the native tissue repair.Methods Totally 130 patients,who underwent pelvic reconstructive surgery in Peking Union Medical College Hospital from September 2013 to September 2016 and were followed up from September 2014 to December 2016,were selected in the study.They were divided into mesh group and native tissue repair group according to whether there was mesh implantation or not,and were also divided into 3-month group and 1-year group by the different follow-up time.The pelvic floor muscle function,the life quality and the sexual life quality were evaluated at 3 months and 1 year after the operation.Results There was no significant difference in the pelvic floor muscle strength between the mesh and the native tissue repair group,as well as between the different follow-up groups (P ＞ 0.05).There were significant differences in vaginal dynamic pressure and PFIQ-7 score between mesh and native tissue repair group (P=0.005,P=0.037).The mesh group was better than the native tissue repair group.In mesh,only Aa (P=0.029)and Ba (P=0.031)of POP-Q were related to vaginal dynamic pressure in different operative methods.The type Ⅱ pelvic floor muscle strength was associated with Bp (P=0.041).After 3 months of the operation in mesh group,the type Ⅰ pelvic floor muscle strength was related to Aa (P=0.026),Ba (P=0.038),C (P=0.038),the type Ⅱ pelvic floor muscle strength was relevant to Aa (P=0.049),Ba (P=0.025),C (P=0.011),Ap (P=0.032),Bp (P=0.005) at 3 months after operation.The type Ⅰ pelvic floor muscle strength was associated with Aa (P=0.015),Ba (P=0.037)in 1-year follow-up.Conclusion Mesh dose not affect the pelvic floor muscle strength.Pelvic floor reconstruction can improve pelvic floor function.Whether pelvic floor muscle training (PFMT) will improve the function of pelvic floor muscles after pelvic reconstruction surgeries needs further study.
