Objective: to compare the severity of the urinary tract wall damage from direct electroimpulse and electrohydraulic application.

Materials and methods. Tissues were collected during the open operations. Electroimpulse lithotripter “Urolith 150M” and electrohydraulic lithotripter “Combilith” were under investigation. Impulse energy for “Urolith 150 M” was 0.4-1.0 J, probe diameters – 2.7-6.0 Fr. Impulse energy for “Combilith” was 0.36-0.96 J, probe diameter – 3.0-7.0 Fr.

Aim of the study was to compare the efficacy of the artificial stone desintegration between new nanosecond electroimpulse lithotripter (NSEIL) standard electrohydraulic lithotripter (EGL). Two types of “stones” were used, which simulated hard and soft urinary stones and were made of dental ultrastrong gypsum BegoStone. EGL was performed using sounds of 3 diameters: 3.0 Fr, 4.5 Fr and 7.0 Fr; NSEIL – using sounds 2.7 Fr, 4.5 Fr and 6.0 Fr.

Aim: to estimate efficacy and safety of the retrograde contact electroimpulse ureterolithotripsy (RECULT) depending on the stone size and location.

Goal. The aim of the study was to determine the efficacy and safety of electro-lithotripsy (EILT) apparatus “Urolit-105M” in patients with different localization of urinary stones.
