Objectives: The aim of the study was the measurement of blood flow in uterine arteries and endometrial vessels in women with postmenopausal bleeding using "power" angio Doppler technique, Materials and Methods: 256 patients diagnosed and treated because of postmenopausal bleeding participated in this study. Using doppler technique blood flow indices: pulsatility index (PI), resistance index (RI) and time average maximal velocity were measured., Results: Neovascular arteries in endometrium were found in 87,7% patients with endometrial carcinoma, 21,9% cases of endometrial hyperplasia and in 5,7% women with normal endometrium. A significantly lower PI and RI in endometrial vessels and uterine arteries were obtained in endometrial cancer cases than in patients with endometrial hyperplasia. TAMXV measured in endometrial vessels and uterine arteries was significantly higher in patients with endometrial cancer when compared to the patients with endometrial hyperplasia., Conclusions: Transvaginal ultrasonography with the "power" angio Doppler is a valuable diagnostic method in cases of early endometrial pathologies. The measurement of blood flow indices in endometrial vessels and uterine arteries is useful to differentiate benign and malignant endometrial pathologies.

Unlabelled: THE OBJECTIVES: The aim of this study was to evaluate the clinical value of blood flow indicies for differentiating between benign and malignant ovarian tumours., Materials and Methods: Realisation of the aim was based on the analysis of examinations' results of 686 ovarian tumors. For each recorded blood flow wave the followind parameters of examined tumor vessels were analysed: pulsatility index (PI), resistance index (RI), peak systolic velocity (PSV), time-averaged maximum velocity (TAMXV) and maximum and diastolic velocity (MEDV). Apart from conditional probabilities we also presented assessing areas under the ROC curves, which introducted information over practical usefulness of each test., Results: Vascular perfusion was observed in 100% of malignant tumors and 92% of non-malignant tumors. In group of patients with malignant tumors PI and RI were significantly lower; and PSV, TAMXV and MEDV were higher than in group with non-malignant tumors. (p<0.05), Conclusions: Transvaginal ultrasonography with the Doppler technique is valuable diagnostic method in preoperative differentiation of tumor malignancies. The best predictive value in analysed group was observed for PI (AUROC=o.87) and MEDV (AUROC=0.86). Similar correlation was observed for premenopausal patients. In group of postmenopausal patients the best predictive value was for RI (AUROC=0.90) and MEDV (AUROC=0.88).

Objectives: The purpose of the study was to evaluate the helpfulness of sonomorphological index in preoperative diagnosis of ovarian tumours., Material and Method: 686 patients diagnosed and treated because of adnexal tumours were analyzed. At the admission day the patient underwent an ultrasonographical examination that stated morphology of tumour using the sonomorphological index (SM)., Results: The sonomorphological index demonstrated high prognostic values: accuracy - 80.6%; sensivity - 86.7%; specifity - 77.0%. During the study, histopathological types of ovarian tumours with the lowest prognostic values were appointed. Among malignant tumours the lowest sensitivity of the test corresponded with: dysgerminoma and folliculoma. Among benign tumours the lowest helpfulness in preoperative diagnosis of ovarian tumours the sonomorphological index demonstrated in following histopathological types: mucinouse cystadenoma and adult teratoma. Particular histopathological diagnosis is the tubo-ovarian abscess--all analyzed cases had a false positive result in the test., Conclusions: In all histopathological types of malignant and benign tumours mentioned above, the use of the sonomorphological index require caution. To increase accuracy of preoperative diagnosis based on ultrasonographical examination, additional Doppler examination and also biochemical markers concentration should be considered.
