[Vaginosonography in gynecology]

Vaginosonography is a new method for gynaecological diagnosis. Its special advantage is to reach the uterus and the ovaries at close range. A structural refinement of the surrounding tissue allows to better coordinate individual structures to the different organs. A further advantage is, that a filled bladder is not required. At the first time diagnostic ultrasound can be used in corpulent patients as well. Vaginosonography is of special importance in the diagnosis of the endometrium according to the event of cycle identifying different types of amenorrhea, and also informative during the climacteric period. Besides the demonstration of the endometrium the time of ovulation can be determined by folliculometry, and an exceeding follicular growth can be stopped at the right time. Transvaginal puncture of follicles is a quicker and easier technique than the usual laparoscopic approach. Early diagnosis of pregnancy is of great importance as well. Using vaginosonography, a missed abortion and an extrauterine pregnancy can be varified in a simple way. A cervical insufficiency can be evaluated in a better way by the determination of the opening of the internal orificium of the cervix. There is further use of the method in other fields of gynaecology.
