The use of Doppler technology in patients with renal colic is known since the mid 2000s, with Doppler technology, mainly used to actually visualize small concrements in the lumen of the urinary tract based on a twinkling-artifact. Also in many publications there are materials on the change in the parameters of arterial renal blood flow in children with acute urinary tract obstruction in the form of a reliable increase in the parameters of peripheral resistance. Venous renal blood flow has not been studied. In addition, almost all studies concern only the adult contingent of patients. In the own study, the first experience of a comprehensive assessment of renal blood flow in children with acute urinary tract obstruction in the dynamics of the pathological process is presented. A reliable increase in the resistive characteristics of arterial renal blood flow during an acute period of obstruction and a sharp increase in the venous blood flow rate in interlobar veins on day 2-3 from the onset of the disease are shown. In a single case a child with left-sided renal colic has a massive renoreteroperitoneal shunt of venous blood.

The review of foreign literature devoted to the method of cone-beam computed tomography of mammary glands is presented, the experience of which is absent in the scientific works of domestic scientists. Analyzing the results of using this technique in diagnosing various changes in the mammary glands (including cancer), we can confidently state that the cone-ray computer tomography has a huge diagnostic and differential-diagnostic potential.

A clinical case of breast sarcoma is presented. Radiation and morphological diagnostics are of particular interest. According to mammography and ultrasound, no direct signs of malignancy were identified (BI-RADS, category 4). The results of the cor-biopsy corresponded to the leaf-like tumor. After sectoral resection, sarcoma of the mammary gland was verified.

The cases of successful visualization and differential diagnosis of lesions of the thoracic wall structures (fresh and consolidated fractures of the ribs, damage to the costochondral joint). As a result of observation, it was noted that the information content of ultrasound scanning was high in differential diagnosis of injuries of ribs and costochondral joint.

Fire penetrating wounds of the heart in the vast majority of cases lead to the death of the victim at the scene of the injury. In this clinical observation, the case of left ventricular injury detected at the stage of specialized surgical care using multi-cut computed tomography (MSCT) is demonstrated. Timely diagnosis of the nature of heart damage, determination of the location of the foreign body, the choice of optimal access allowed for successful surgical intervention in the wounded. The results of MSCT angiography, ultrasound and a brief literature review are presented.

Neonatal renal vein thrombosis is a life-threatening condition which can lead to renal atrophy, and with a bilateral lesion - to renal failure. The association renal vein thrombosis with inferior vena cava thrombosis, hemorrhage to the adrenal glands, thrombosis of other localization and hemorrhages to other internals is also possible. Follow-up observations reveal nephrosclerosis in about a third of the cases. The case of prolonged follow-up observation of the boy who underwent bilateralrenal vein thrombosis, inferior vena cava thrombosis, thrombosis of the left branch of the portal vein, hemorrhage to the adrenal glands and the cerebral parenchymal hemorrhage in the neonatal period is presented in the publication. After 8 years of follow-up, nephrosclerosis on the right, preservation of left kidney functions with the development of massive renoretroperitoneal venous shunts were recorded. Laboratory examination did not reveal the signs of renal insufficiency.
