Abstract：Objective To investigate the existence of vaginal lactobacillus after sigmoid vaginoplasty,skin graft vaginoplasty and porcine small intestinal submucosa (SIS) vaginoplasty.Methods Totally 23 women with sigmoid vaginoplasty,18 women with skin graft vaginoplasty and 20 women with SIS vaginoplasty who visited Shanghai Ninth People' s Hospital were enrolled in this restropective study,and vaginal lactobacillus were cultured and detected in all the cases at 1 week,1 month,and 6 months respectively after the vaginoplasty.Thirty healthy females were collected as control group.The positive rates of vaginal lactobacillus were compared in all the groups.Results The positive rates of vaginal lactobacillus at 1 week in sigmoid vaginoplasty group (17.39％),skin graft vaginoplasty group (16.67％) and SIS vaginoplasty group (20％) were lower than those in the control group(60％),with statistic differences(P ＜ 0.05).With regard to the positive rate of vaginal lactobacillus at 1 month after vaginoplasty,there were no significant differences between sigmoid vaginoplasty group (34.78％),SIS vaginoplasty group (35％) and the control group(P＞ 0.05),whereas statistic difference was found between the skin graft vaginoplasty group(22.22％) and the control group(P ＜ 0.05).The positive rates of vaginal lactobacillus at 6 months in sigmoid vaginoplasty group (47.83％) and SIS vaginoplasty group (40％) were similar to those of the control group(P ＞ 0.05),while in the skin graft vaginoplasty group(27.78％),it was statisticly different from the control group(P ＜ 0.05).Conclusion Within 1 week,lactobacillus begins to appear and clone in the vagina after vaginoplasty.One month and 6 months after vaginoplasty,the lactobacillus in patients receiving the sigmoid vaginoplasty and SIS vaginoplasty nearly reaches the normal lactobacillus positive rate,while the lactobacillus positive rate in patients undergoing skin graft vaginoplasty is lower,which needs further study.
