Early versus delayed shock wave treatment for leftover kidney stones after percutaneous nephrolithotomy

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective, randomized comparison of two timings for ESWL after percutaneous nephrolithotomy in patients with residual renal stones 15 mm or smaller. Eligible adults are randomized to receive ESWL early after PCNL or after a delayed interval, and are followed for stone clearance and procedure-related complications. Key outcomes include stone-free rate, need for additional interventions, and rates of bleeding or infection. The work is conducted at a single center (Beni‑Suef University Hospital) with standard ESWL protocols and predefined safety monitoring.
