A Prospective Randomized Comparison Between Shock Wave Lithotripsy and Flexible Ureterorenoscopy for Lower Caliceal Stones ≤2 cm: A Single-Center Experience

Abstract

Both SWL and RIRS are safe and efficacious for lower caliceal calculi ≤20 mm. For stones <10 mm, SWL was less invasive and safer than RIRS with efficacy comparable to it. However, for 10-20 mm stones, RIRS was more effective, with lesser retreatment rate.
