Preoperative sonographic evaluation of patients with endometrial carcinoma.

OBJECTIVE: The aim of the study was to evaluate the possibilities of endovaginal ultrasound in the preoperative clinical assessment of patients with endometrial carcinoma. METHOD: Sixty-four postmenopausal women with a diagnosis of endometrial carcinoma after dilatation and curettage were scanned before operation with a 7.5-MHz endovaginal probe. RESULTS: The location of the process and depth of myometrial invasion were estimated correctly in the vast majority of patients. Spread beyond the uterus and distance from the serosa could not be estimated precisely. CONCLUSION: Preoperative evaluation and staging of endometrial carcinoma are possible and useful for gynecologists, as they provide information on tumor location, depth of myometrial invasion, and involvement, if present, of the lower uterine segment or cervix.

[Artificial abortions in Bulgaria and their prevention].

Authors go into one extremely important problem for the family, woman, natality and family planning in Bulgaria. Scarcely during the last years it can be observed a slight reduction of the frequency of induced abortions. The average age of women having an abortion is high--about 30, which shows, that induced abortion is still a method of regulation fertility in intergenetic interval. The rate of those who have induced abortion under the age of 19 in Bulgaria is 7.8 to 53.3%, in Czechoslovakia, 6.7%, in DDR--50.0%, Greece--68%, Hungary--8.9%, Sweden--15.8%. The rate of done again induced abortion is higher, that is a result of bad preventing activities during the first abortion. Similar is the tendency of growing number of unmarried women having an induced abortion, as it is in the other countries: from 16.4% in 1980 to 21.7% in 1987. Bulgaria is on the third place in Europe according to the absolute number of dead cases after abortion (maternity death, after Rumania and USSR).

[The importance of x-ray pelvimetry for the prognosis of pelvic dystocia].

The frequency of roentgenological pelvimetry at the Research Institute of Obstetric and Gynecology during 1988 is 4.79%. Thirty-five pelvimetries out of 276 (12.68%) were urgent, but the remaining 241 (87.32%) were planned. Pelvimetries showed normal measurements in 113 of pregnant women (40.94%), but there was shortening in one or more diameters of the single planes of the pelvis in 163 women (59.06%). The measures of the diameters of the pelvic cavity were shortened most frequently, more rarely at the pelvic inlet and most rarely at the pelvic outlet. Changes in the bony pelvis were indicated after secondary traumatic deformity of the pelvis. The role of roentgenological pelvimetry in taking decision for delivery of breech presentation of the fetus was analyzed. It is pointed out that the roentgenological pelvimetry is the single, easy, convenient, safe and available method for determination of pelvic diameters, respectively for prognosis of pelvic dystocia.
