[Treatment of erectile dysfunction in cases of venous and corporovenous insufficiency of phallus].

A total of 230 patients of different age with impaired venous drainage of penis cavernous bodies were examined. Test with intracavernous injection of papaverin, dopplerography of the vessels and cavernosometry were employed. To treat venous and corporovenous insufficiency, it is suggested to make a resection of the deep dorsal vein, ligation of the superficial and circular veins with suturing tunica albuginea. In negative result of the surgery viagra in a done 50 (100) mg is recommended or penile implants.

[The current diagnostic procedure in chronic pathology of the veins of the lower extremities].

Stepwise (out- and inpatient) examination forms the basis of diagnostic examination tactics in chronic abnormalities of the veins. Noninvasive ultrasonic methods of studying the venous system are preferred. With the gradual formation of groups of patients with an affection of the veins, invasive isotope and angiographic methods are supplemented. The authors emphasize that such examination of patients in stages raises the efficacy and the quality of diagnosis in individuals with chronic venous abnormalities.

[Ultrasonic examination in the diagnosis of chronic diseases of the veins of the lower extremities].

Noninvasive diagnosis of chronic diseases of the lower limb venous system is an urgent problem of modern phlebology. Ultrasonic examination (USE) makes it possible to judge adequately the condition of the deep and surface veins and, consequently, to improve significantly the management of varicose and post-thrombophlebitic diseases. The authors elaborated an original method for the diagnosis and appraisal of the condition of the lower limb venous system by means of ultrasonic scanning and various functional tests for determining the character of affection of the venous valvular apparatus. Examination of more than 200 patients with primary varicosities and post-thrombophlebitic disease, the use of highly-resolving ultrasonic equipment, and comparison of the results of USE with the findings of radiocontrast phlebography (agreement in 99.8% of cases) allow the conclusion that noninvasive ultrasonic methods must be used widely in appraising the venous status in patients with chronic diseases of the venous system of the lower limbs.

[The informativeness of ultrasonic scanning methods in obliterating diseases of the arteries of the lower extremities].

The authors studied the diagnostic possibilities of ultrasonic angiography and doppler sonography as compared to digital subtraction angiography. A total of 506 arterial segments was examined in 116 males suffering from various degree of atherosclerosis obliterans of the lower limb vessels. The coincidence of and disparity in the diagnosis were analysed on the aortoiliac and femoropopliteal levels according to three criteria: normal vessel, stenosis, occlusion. The diagnostic efficacy was appraised with the use of the Kapp index (K), the percentage of absolute coincidence of the diagnoses, sensitivity, and specificity. The precision of doppler sonography was found to be comparable with that of digital subtraction angiography. On the aortoiliac level K-0.68 +/- 0.06, on the femoropopliteal level K = 0.78 +/- 0.05. The diagnostic possibilities of ultrasonic angio-scanning were significantly lower. Thus, on the aortoiliac level K = 0.28 +/- 0.07, on the femoropopliteal level K = 0.4 +/- 0.05. Doppler sonography is therefore a reliable noninvasive method in the diagnosis of obliterating diseases of arteries of the lower limbs.

[Extracorporeal lithotripsy in cholelithiasis].

The authors describe their first experience with treatment of 46 patients with extracorporeal lithotripsy. Its high effectiveness has been shown. The method is atraumatic and harmless, there is no risk of lethal outcome. These properties allow using the method both in patients having contraindications to operation because of their critical general state and in patients who refused to be operated upon.

[The potentialities of Doppler sonography in evaluating the distal vascular channel in chronic obliterating diseases of the arteries of the lower extremities].

The work deals with the techniques of examination of the leg arteries in patients with atherosclerosis obliterans of the lower limb vessels by the method of doppler sonography (DS) and dopplerography. The authors examined 111 arterial segments in 43 patients. The results of these methods were compared with the findings of radiocontrast angiography. The absolute percentage of the coincidence of diagnosis (AP), sensitivity (Se), and specificity (Sp) of these methods were calculated according to two criteria--"normal" vessel and "occlusion". In DS, AP was 93 +/- 2%, Se-95 +/- 4%, Sp-93 +/- 2%, the respective values in dopplerography were 81 +/- 3%, 84 +/- +/- 11%, and 79 +/- 4%. The difference between these methods according to AP and Sp was statistically significant (p less than 0.001). The authors believe that the higher percentage of coincidences of diagnosis in DS is linked with the possibility of purposeful study of the blood flow in the vessel, being guided by its image.

[Ultrasonographic examination in the differential diagnosis of jaundice].

The results of complex examination of 352 patients with various forms of jaundice are discussed. All patients underwent ultrasonic examination (USE). Comparison of the results of USE with those of other methods of examination showed it to possess diagnostic value in patients with various forms of jaundice. The highest accuracy of the diagnosis was in patients with parenchymatous jaundice. In patients with benign jaundice as well as in those with jaundice of a neoplastic origin USE is a valuable method in determining the sequence of manipulations in the diagnostic program, but it cannot be a means of making the final diagnosis.

[Assessment of the results of implantation of an anti-embolic cava-filter using the method of ultrasonic scanning].

By the method of ultrasound scanning, 56 patients were examined at the early and 115 patients at the late period after the percutaneous implantation of a cava-filter. Ultrasound scanning was performed in the cross and longitudinal section planes. In 28 patients, the embolic occlusion of the cava-filter was revealed, in 19-thrombosis of infrarenal inferior vena cava (IVC). Neither migration of the cava-filter, nor damage to the IVC wall was revealed. Ultrasound scanning permits to define the thickness of the IVC wall at the zone of the implanted filter.
