Data for continuous variables are mean ± SD and data for categorical variables are number (percentage). *Preceding coitus is defined as coitus 24 hours prior, †p values were compared between surgery group and conservative management group, ‡Variables with p values less than 0.05. HU = Hounsfield unit, Mx. = management
