[Multivariate analysis for pelvic floor dysfunction]

To investigate the risky factors for pelvic floor functional disorder.

A total of 346 patients, who undergone surgery for pelvic floor reconstruction from January 2007 to December 2013 in the Third Affiliated Hospital of Zhengzhou University, were enrolled for this study and served as an experimental group. Meanwhile, 349 female healthy subjects were selected as a control group. The data including the times of gestation and parity, history of menopause, hysterectomy surgery, uterine fibroid and leucorrhea were recorded.

Compared with the controls, the numbers of people with hysterectomy, menopause and clean vagina≥III degree, lack of lactobacillus as well as the times of gestation and parity in the experimental group were significantly increased (P<0.05). The history of hysterectomy, the times of gestation and parity and lack of lactobacillus in vagina were the independent risk factors of pelvic floor dysfunction.

The history of hysterectomy, the times of gestation and parity, and clean vagina may involve in the occurrence and development of pelvic floor functional disorder, and the existence of lactobacillus in the vagina might be a protective factor.
