[Vaginal sonographic imaging of the ovula Nabothi].

Twenty patients, showing retention cysts in vaginosonographic examination, were included in our study. We differentiated between superficial and deep located Nabothian cysts. Fourteen cases showed primarily visible superficial cysts, the other six could only be detected vaginosonographically. The Nabothian cysts varied in size from 4 to 26 mm, the average diameter was 13 mm. Only four cases showed solitary Nabothian cysts, the other sixteen cases were multiple. The clinical significance of Nabothian cysts in the field of sterility diagnostics, especially the deep located retention cysts, cannot be assessed at present.

[Color Doppler flow measurements in uterine cancers].

Pulsed Doppler Flow Measurements in patients suffering from collum cancer using a coloured pulsed Doppler technique measurements of blood flow of the uterine artery were performed in a group of 35 patients suffering from an inoperable collum cancer (stage II and III according FIGO) and compared with a collective of 30 healthy women with normal anamnesis. The mean pulsatility index (PI) was significantly lower in the sick group (stage II 1.6 +/- 1.17, stage III 0.76 +/- 0.21) than in the healthy group (PI = 3.18 +/- 0.99) (p less than 0.01). In 14 subjects of the last group there was no significant difference in PI between the left and right uterine artery (left: PI 2.81 +/- 0.83), right: PI 2.78 +/- 0.76).

[Comparative study of introital sonography and the urethrocystogram in women before and after surgery for stress incontinence].

In a prospective study of sonographic and radiographic methodologies we compared morphologic bladder data in 30 patients before and after stress incontinence surgery. 18 women were subject to colposuspension according to Burch due to recurrent stress incontinence, 12 women underwent anterior colporrhaphy. Visualisation of bladder, urethra and beta-angle was adequate with both methods. The good visualisation of the anatomical and functional situation of the vesico-urethral area is a major benefit of introital sonography.

Ultrasonic Doppler flow studies of the uterine arteries in women with cervix cancer.

The main characteristic of malignant tumors is their capacity for local destructive spread as well as infiltration into the adjacent tissue. The present study was carried out to evaluate the hemodynamic alterations in patients with advanced cervix cancer. Data of 34 patients with cervix cancer are compared to 30 healthy women with normal history. The mean pulsatility index (PI) was significantly lower in cancer patients (PI = 1.75 +/- 1.27) than in controls (PI = 3.18 +/- 0.99). Use of noninvasive Doppler ultrasound study physiology of uterine hemodynamics in patients with cervix cancer is of great clinical relevance and paves the way for further investigations in screening programs for cervix cancer.

Early detection of ectopic pregnancy by transvaginal ultrasound.

Transvaginal (TVU; 19 patients) and transabdominal ultrasound (TAU; 24 patients) were compared in their ability to visualize an ectopic pregnancy. The direct visualization of ectopic pregnancy (EUP) was 25% with TAU and 94.7% with TVU. All women had a proven EUP in laparoscopy. TAU approach showed a significant inferiority (P less than 0.02) and TVU a superiority (P less than 0.08) in comparison to clinical examination. 83% of 43 women had spotting. Nonspecific signs for EUP like fluid in the pouch of Douglas was seen in 20.9%. Thin endometrium was seen in 6.9%, in 37.2% the thickness of endometrium was under 10 mm, in 55.8% more than 10 mm. An intrauterine pseudogestation sac was detected in 6.9%, corpus luteum formation in 37.2%.

[Gynecologic Doppler ultrasonography].

The resistance of the vessel of the ovarian artery changes during the cycle. At the time of ovulation the resistance of the vessel of the ovarian artery decreases under the influence of steroid production in the ovary. The resistance decreases and the blood flow increases. In our study we could show that women with a normal cycle have low pulsatility indices in the ovarian arteries when oestradiol is rising. In women with PCO-Syndrome the blood flow in the ovarian artery is very low in spite of the fact that the patients got hormonal treatment. On the day of follicular puncture in our IVF-group and also on the day before, the pulsatility-index of the ovarian artery was very high in patients with PCO-Syndrome and it was significantly lower in patients with normal cycle. The women with PCO-Syndrome had also low oestradiol levels in the plasma. In the group with PCO-Syndrome no woman became pregnant, women with high oestradiol levels and low PI of the ovarian artery at the time of follicular puncture became pregnant in 19%.

[Vaginal ultrasound study of the normal and incompetent cervix: attempting a mathematical assessment].

A group of 217 pregnant patients was examined by vaginosonography. The group could be divided into 62 patients with incompetent cervix and 155 patients with normal findings. We measured the width of the internal os, the length and the thickness of cervix of all patients in intervals of 14 days. We registered a dynamic process pattern of cervical, morphological changes in the group with preterm delivery. We tried to reduce these cervical changes to an arithmetic formula.

[The value of vaginal ultrasonography in early pregnancy].

Heart action was detected in our first group of 150 pregnant women during the early period of pregnancy (5th to 8th week post menstruationem) in 25% at the end of the 5th week of pregnancy, in 85% at the end of the 6th and, in 100% in the 7th week. In our second group of 59 women with tubal pregnancy, confirmed by laparoscopy, it was possible to detect the extrauterine pregnancy transabdominally in 25% and transvaginally in 94.7% via sonography (p = 0.03). Extrauterine pregnancy was easier detectable by vaginosonography due to the proximity of the organ and the better power of resolution, as a direct sign of extrauterine ring formation surrounded by a circular wall-like structure.

[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.

[Comparison of transabdominal and transvaginal sonography in extrauterine pregnancy].

In 19 patients the transvaginal (TVU) and in 24 patients the transabdominal (TAU) ultrasound approaches were compared in their ability to identify by visualisation the adnexal mass of ectopic pregnancy. The direct visualisation of ectopic pregnancy (EUP) was 25% in TAU and 94.7% in TVU approach (p less than 0.03). All women had a proven EUP in laparoscopy. TAU approach showed a significant inferiority (p less than 0.02) and TVU a significant superiority (p less than 0.08) in comparison to palpation. 83% out of 43 women had spotting. Unspecific signs for EUP like retrouterine fluid was seen in 20.9%. Line formed endometrium was seen in 6.9%, in 37.2% the thickness of endometrium was under 10 mm, in 55.8% more than 10 mm. An intrauterine pseudo-gestation sac was detected in 6.9%, corpus luteum formation in 37.2%. With vaginosonography organs can be seen at close range, therefore it is easier to recognise the specific signs of EUP - an extrauterine ring - formation surrounded by a dam-like structure of the tube.

[Practical use of blood flow measurement with pulsed ultrasound in the 3d trimester of an at-risk pregnancy].

Using a pulsed Doppler technique measurements of blood flow of the arcuate artery, umbilical artery and foetal aorta were performed in the third trimenon in a group of 163 patients with risk pregnancies and compared with the weights of the newborn. In normal values of blood flow of the arcuate artery (n = 144) less than 10% of the weights of the newborn were below the tenth percentile. In pathological values (n = 19) about 42% newborn werde below the tenth percentile. In normal values of blood flow of the umbilical artery (n = 158) about 10% of the newborn were below the tenth percentile. In pathological values (n = 5) all newborn were below the tenth percentile. In normal values of blood flow of the foetal aorta (n = 139) about 12% of the newborn were below the tenth percentile. In pathological values (n = 4) all newborn were below the tenth percentile. Of the group with "normal" blood flow data a sub-group was formed with flow values between the first and second standard deviation. These were labelled "suspicious" and had shown a significant correlation with the birth weights of the newborn. Based on these experiences a schema was prepared comprising the blood flow measurements and cardiotocography, from which recommended clinical procedures were derived.

Vaginosonographic surveillance of cervix after conization.

A high risk patient, after conization and following abortion, was supervised vaginosonographically from the 12th gestational week. The premature shortening of the cervix, but also its almost pain-free opening, were observed with the help of this method. It seems that the lower part of the uterus can be readily visualized and objectively assessed' with ultrasonic diagnosis, especially by vaginal sonography.
