FIELD: medicine, urological ultrasound diagnostics.
SUBSTANCE: ureterectasia should be developed below prepyeloureteral department, one should cause functional obstruction in ureterovesical segment: a patients should fill urinary bladder to achieve high values of pressure in it, restrict urinary passage through ureterovesical anastomosis, perform medicinal polyuria due to intravenously introduced lasix at age dosage at simultaneous introduction of an analgesic. About 10 min after lasix introduction one should perform ultrasound testing in the course of which an increased upper third of patient's ureter enables to localize pyeloureteral segment, detect the length of obstruction and due to Doppler scanning detect either availability or absence of inferior polar vessel. The method enables to determine indications to apply open surgical techniques of hydronephrosis and endoscopic methods (endopyelotomy).
EFFECT: higher efficiency of ultrasound diagnostics.
