Use

With solid vaginal dilators, the patient starts with the smallest dilator size, then gradually increasing until the largest dilator size is reached. This practice can be accompanied by breathing exercises in order to relax the pelvic floor muscles. Dilation acts should not cause pain or bleeding. Dilatation with rigid dilators must be done carefully as vaginal perforation and urethral injury may occur. There is no consensus on the frequency and duration of using vaginal dilators. In case of vaginal expanders, the therapist or the patient introduces the deflated balloon into the vagina and then inflates it gently until the required diameter is obtained.
