Summary

This clinical trial compares two techniques of extracorporeal shock wave lithotripsy (ESWL) - energy ramping versus fixed dose - in adult patients with renal stones. The study aims to evaluate stone-free rates, retreatment needs, and safety outcomes across multiple clinical sites in Egypt.

Conditions

  • Renal Calculi

Interventions

PROCEDURE

Extracorporeal shock wave lithotripsy

Fixed Voltage (experimental): Subjects receive shock wave therapy at a constant energy level (e.g., 20-22 kV) for the entire duration of the session. Standard delivery includes approximately 3,000 shocks at a frequency of 60-90 shocks per minute. Voltage Ramping (control): Subjects receive shock wave therapy starting at a low energy level (e.g., 6-10 kV) for an initial "priming" phase of 100-500 shocks. Energy is then escalated in predefined increments (e.g., 1-2 kV every 250-500 shocks) until reaching the target therapeutic voltage.
