Q: Question: Do treatment of Renal Stones ≥20 mm with Extracorporeal Shock Wave Lithotripsy?
Answer: For renal stones with a surface area ≤400 mm2 and a radiodensity equal to or less than that of the 12th rib as determined by a KUB film, ESWL may be considered the first line of treatment, even for stones with a diameter ≥20 mm. For large stones requiring repeat treatments, the surface area of the residual stones after the first ESWL is a predictor of the final treatment result.
