[Ultrasonic diagnosis of polypoid formations of the gallbladder]. / Ul'trazvukovaia diagnostika polipoidnykh obrazovanii zhelchnogo puzyria.

Altogether 4000 patients were examined using an ultrasonograph Toshiba SAL 38AS working in the real time mode. 1.08% of the patients were diagnosed to have small polypoid formations of the gallbladder which, in many cases, could not be recognized at oral cholecystography. Routine repeated sonography of the gallbladder demonstrated that in 94.9% of cases, small polypoid formations did not increase in size for 12 to 18 months. Four patients subjected to cholecystectomy manifested polypous cholesterosis of the gallbladder.

[Diffuse thickening of the gallbladder wall detectable during echography]. / Diffuznoe utolshchenie stenki zhelchnogo puzyria, vyiavliaemoe pri ékhografii.

Echographic examination of 3900 patients showed enlargement of the gallbladder wall in 3.5%. It was seen not only in cholecystitis but also in diffuse liver injury, portal hypertension, chronic heart failure and in other pathological conditions. Examples are given of 3 different sonographic versions of enlargement of the gallbladder wall. In some patients' groups (with diffuse liver injury, chronic heart failure, portal hypertension), a correlation was established between the thickness of the gallbladder wall and the diameter of the portal vein. It is assumed that echographic demonstration of the enlarged gallbladder wall in patients with diffuse liver injury may serve an early sign of portal hypertension.

[Evaluation of the indicators of dynamic renal scintigraphy using the radiopharmaceutical preparation In-113m-DTPA in patients with chronic glomerulonephritis before and after heparin therapy]. / Otsenka pokazatelei dinamicheskoi stsintigrafii pochek s primeneniem radiofarmatsevticheskogo preparata 113mIn-DTPA u bol'nykh khronicheskim glomerunefritom do i posle geparinoterapii.

In 70 patients with a morphologically verified diagnosis of chronic glomerulonephritis, functional computer-aided scintigraphy of the kidneys was performed before and after heparin therapy. Improvement in the scintigraphic parameters following heparin therapy was apparent as the reduction of the time of the radiopharmaceutical passage and the decrease of spastic excretory disturbances. A certain deterioration of the scintigraphic parameters after heparin therapy was found in patients with fibroplastic and focal sclerotic glomerulonephritis associated with renal insufficiency.
