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.

Hypotonic degassed water was used as the coupling fluid during the ESWL procedure.
0.9% NaCl (isotonic) solution was used as the coupling fluid during the ESWL procedure.
3% NaCl (hypertonic) solution was used as the coupling fluid during the ESWL procedure.

Stone Fragmentation Success Rate
The percentage of patients achieving successful stone fragmentation, defined as residual fragments smaller than 4 mm.
Time frame: 2-4 weeks after the ESWL procedure
Post-ESWL Pain Scores
Pain intensity assessed using the Visual Analog Scale (VAS), where 0 represents no pain and 10 represents the worst imaginable pain.
Time frame: Immediately after the ESWL procedure
