Effect of Distance Piezoelectric Nephrolithotrispy on Renal Hemodynamics in Patients with Urolithiasis

The renal hemodynamics is studied in 50 patients before and after treatment using the distance piezoelectric nephrolithotri psy method by ultrasound scanning system in conditions of colour doppler and energy mapping. The reliable decrease of the index values to the initial indices occurred in two days after lithotripsy in patients with extrarenal structure of the calicle and pelvis system and only in seven days in patients with intrarenal structure in conditions of retaining the urine passage. The necessity of doppler- monitoring for determination the terms of performing regular lithotripsy seance is stressed taking into account the variation of the terms of recovering renal hemodynamics.
