No results posted yet for this study

Summary

The purpose of this study is to investigate the effect of different salt concentrations (tonicity) in the coupling fluid used during Extracorporeal Shock Wave Lithotripsy (ESWL). The study compares three types of coupling fluids: hypotonic (degassed water), isotonic (0.9% NaCl), and hypertonic (3% NaCl) solutions. Researchers aim to determine which solution provides the best stone fragmentation success while minimizing procedure-related pain and skin complications.

Interventions

PROCEDURE

Hypotonic degassed water coupling

Hypotonic degassed water was used as the coupling fluid during the ESWL procedure.

PROCEDURE

Isotonic (0.9% NaCl) coupling

0.9% NaCl (isotonic) solution was used as the coupling fluid during the ESWL procedure.

PROCEDURE

Hypertonic (3% NaCl) coupling

3% NaCl (hypertonic) solution was used as the coupling fluid during the ESWL procedure.
