A Prospective Study Of Pelvic Floor Muscle Function After Pelvic Floor Reconstruction

ObjectiveTo study the pelvic floor muscle function and the life quality after two kinds of pelvic floor reconstruction:the mesh and the native tissue repair.Methods130 patients who underwent pelvic reconstructive surgery in Peking Union Medical College Hospital from September 2013 to September 2016 and follow-up from September 2014 to December 2016 were selected in the study.They were divided into mesh and native tissue repair by mesh implantation or not,and also were divided into in 3 months and in 1 year by the different follow-up time.The pelvic floor muscle function and the life quality、the sexual life quality was evaluated at 3 months and 1 years after the operation.ResultsThere is 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 are significant differences in vaginal dynamic pressure and PFIQ-7 score between mesh and native tissue repair(P=0.005,P=0.037).The mesh is better than the native tissue repair.In mesh,only Aa(P = 0.029),Ba(P = 0.031)with POP-Q was related to vaginal dynamic pressure of different operative methods.The type II pelvic floor muscle strength was associated with Bp(P = 0.041).In 3 months after operation in mesh,the type I pelvic floor muscle strength was related to C(P = 0.018),the type II pelvic floor muscle strength was relevant to Aa(P=0.026)、Ba(P=0.038)、C(P=0.038);The type Ⅱ pelvic floor muscle strength was associated with Aa(P=0.049)、Ba(P=0.025)、C(P=0.011)、Ap(P=0.032)、Bp(P=0.005).The type I pelvic floor muscle strength was related to Aa(P=0.015)、Ba(P=0.037)with 1 year follow-up.ConclusionMesh did 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.
