Aim: To evaluate the efficiency of the drug phytolysin (capsules) in the prevention of complications after extracorporeal lithotripsy.
Materials And Methods: A total of 15 patients diagnosed with urolithiasis and chronic pyelonephritis in the latent phase were treated. The predominant localization of radiopaque stones no larger than 20 mm in size was the collecting system.

Objectives: To compare the efficacy and safety of shockwave lithotripsy (SWL) using a narrow focus or wide focus for renal stones.
Patients And Methods: A double-blind randomised trial included adult patients with a solitary radio-opaque renal pelvic stone of 1-2 cm. Patients were randomised into two groups: narrow-focus (2 mm) SWL and wide-focus (8 mm) SWL.

Context: Shockwave lithotripsy (SWL) shows clear associated benefits for urolithiasis patients.
Objective: To identify and classify SWL complications according to modified Clavien-Dindo grading system while assessing the effect of different patient characteristics, stone parameters, types of lithotripters, and lithotripsy techniques.
Evidence Acquisition: Literature was reviewed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement.
Confocal lens focused piezoelectric lithotripter.

This work focuses on the evaluation of a type of piezoelectric lithotripter with similar dimensions of a commercial lithotripter and composed of either 3 or 4 large lens focused piezoelectric transducers set either in a confocal coplanar C-shape or a confocal spherical shape. Each transducer is made with a 92 mm diameter 220 kHz flat piezoelectric ceramic disc and a 3D printed acoustic lens. Both confocal setups pressure field were measured with a fiber optic hydrophone, and in vitro fragmentations of 13 mm diameter and 14 mm length cylindrical model stones were done in a 2 mm mesh basket.
