FIELD: medicine.
SUBSTANCE: under ultrasound and X-ray control, a nephrostomy course into the calyx-pelvis system is formed. An ureteral casing with an outer diameter of 2.6 mm and inner diameter of 1.9 mm is directed into the calyx-pelvis system cavity. The finest fragmentation of the stone at the background of continuous irrigation is carried out along the working channel of ultraminerefroscope using laser radiation. Stone fragments are evacuated by washing the irrigation liquid through the ureteral casing under the endoscopic control.
EFFECT: effective low-invasive treatment of kidney stones up to 2 centimeters, reduced risk of bleeding and reduced number of postoperative complications, without the need to interrupt lithotripsy and change tools, without the use of a lithoextractor.
