METHOD FOR ASSESSING RENAL VIABILITY BY ULTRASONIC EXAMINATION WITH ECHO CONTRAST IN THE EARLY POSTOPERATIVE PERIOD IN ANURIA AFTER EXTRACORPOREAL NEPHRECTOMY IN THE CONDITIONS OF PHARMACO-COLD ISCHEMIA WITHOUT CROSSING THE URETER WITH ORTHOTOPIC VESSEL REPLANTATION Russian patent published in 2019 - IPC A61B8/06 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to ultrasonic diagnostics, and can be used for assessment of kidney viability by data of ultrasound examination with echocontrast in early postoperative period in anuria after extracorporeal resection of kidney in conditions of pharmaco-cold ischemia without crossing of ureter with orthotopic vascular replantation. In the early postoperative period, ultrasonography is carried out in duplex scanning mode to assess intraorganic blood flow in the kidney. If blood flow in the kidney is not detected by duplex scanning data, ultrasound examination with echo contrast is performed. Ultrasonic sensor is placed in the projection of the right and/or left retroperitoneal space, depending on the side of resection, with the possibility of visualizing the kidney along its entire length. Echoconstrictive substance is introduced in dose of 2.5 ml into a central vein with subsequent introduction of 10 ml of normal saline. Examination is started at the moment of introduction of normal saline and is performed for a time sufficient for recording the arterial and venous phases. Echoconstrictor substance distribution in the renal vessels from the gate to the periphery is estimated, on the basis of which its viability is determined.

EFFECT: method provides an accurate assessment of the vascular bed of the kidney in the early postoperative period.
