Ultrasonic and x-ray investigations were performed in 208 urolithiasis suspects. Concrements were diagnosed in 156 of them. X-rays failed to find concrements in 25 patients out of 128 with calyceal concrements diagnosed ultrasonically because of the concrements' small size, their x-ray negativity and ultrasonic hyperdiagnosis. Pelvic concrements were registered in 12 patients by both the methods. Detection of ureteroliths (16 cases) was not an easy task for echography which was, however, rather successful after the lumen extension up to 1 cm. Excretory urography provided additional information on the upper urinary tracts: stricture of the ureteropelvic segment, juxtavesical ureteral stricture, incomplete renal and ureteral doubling (15, 3 and 7 subjects, respectively), etc. Combined application of ultrasonography and excretory urography in urolithiasis facilitates the choice of optimal treatment for it can both localize concrement and assess the condition of the urinary tracts.

A program for the examination of patients with the superior vena caval syndrome, including digital subtraction angiography and computed-tomographic phlebography, is discussed. A combination of these methods is optimal and makes it possible to obtain detailed diagnostic information which is necessary for determining the therapeutic tactics in cases with the compression syndrome.

The state of the major mediastinal veins was studied in 113 patients with central cancer of the right lung upper lobe with metastases to the regional lymph nodes. Routine angiography was performed in 92 patients, digital subtraction angiography--in 21 patients. Vascularization was shown to be more common in and adenocarcinoma. The authors identified 2 groups of angiographic signs: marked and doubtful ones. They have been of opinion that only the presence of marked signs can be a contraindication for surgical intervention. The informative value of routine angiography was compared with that of digital subtraction angiography.

Optimum multimodality examination of the pancreas includes sonographic, radioimmunological, scintigraphic and angiographic studies. Sonography is a method of choice to study anatomotopographic features of the pancreas. The radioimmunoassay is intended both for the mass screening of patients with hepatogastro-duodenal diseases and for the differential diagnosis of chronic pancreatitis by the nature and type of disease. The use of pancreatoscintigraphy should be restricted in view of considerable exposure of patients. Angiography and angioscanning should be performed strictly according to indications with suspicion for a pancreatic tumor.
