Acoustic Impedance Matching in ESWL: A Comparative Analysis of Hypotonic, Isotonic and Hypertonic Coupling Fluids
Acoustic Impedance Matching in ESWL: A Comparative Analysis of Hypotonic, Isotonic and Hypertonic Coupling Fluids
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.
