Abstract

The aim of study was to study the effectiveness of extracorporeal shock-wave lithotripsy and assess its post-procedural complications. Materials and methods. The results of treatment of 200 patients with urolithiasis who were admitted to the Republican Specialized Scientific-Practical Medical Center of Urology in the period 2019-2020 that have been exposed to ESWL because of upper urinary tract (UT) stone(s) prospectively were analyzed. The mean patients' age was 39.7 ± 14.7, BMI - 25.5 ± 4.8 (kg / m2). The affected side: 103 (51.5%) on the right, 97 (48.5%) on the left. The average stone size was 9.0 ± 0.2 (mm), of which 155 (77.5%) < 10 mm, in 45 (22.5%) 11-16 mm. The stones were located in the calycies in 55 (27.5%), in the pelvis renalis in 16 (8.0%), in the ureter in 129 (64.5%) cases. In 180 (90%) patients, there was a dilatation of UT in the form of ureterohydronephrosis / hydronephrosis / calicectasia. Electrohydraulic lithotripsy was performed; the mean generator power was 17.9 ± 0.3 V; the number of strikes was 681.35 ± 192. Results. In 186 (93%) patients, after the first session within 20 days, the stone fragments came off and we got Stone free condition. Renal colic developed in 19 (9.5%), of which 6 (3.0%) due to a steinstrasse, acute obstructive pyelonephritis in 2 (1.0%), of which 1 (0.5%) developed urosepsis. 14 (7.0%) patients required repeated lithotripsy, 2 of them for a steinstrasse. Out of 14 in 10, after the second session, the fragments came off. Also, additional interventions were required: in 3 (1.5%) cases ureteroscopy (URS) with contact lithotripsy; percutaneous nephrostomy in 1 case, URS with stone extraction in 1 case. Conclusions. Systematization of post-procedural complications according to Clavien-Dindo (2004) showed that a total of 40 (20.0%) complications developed: I -19, II - 1, IIIa - 14, IIIb - 5, IVa - 1, IV b -0, V -0.
