Staghorn Stone Treatment with Extracorporeal Shock Wave Lithotripsy: The Fate of Residual Stones
Herein we describe the fate of 48 staghorn stones treated primarily with extracorporeal shock wave lithotripsy (ESWL) within an observation period of up to three years. Thirty patients (61%) who became stone free within eight months had two recurrences (6%) and were retreated within two years. Of 18 patients with residual stones, ten became symptomatic and needed auxiliary treatment, and nine eventually were rendered stone free. At 24 months, 84% of the original 48 patients were stone free, and the remainder were free of symptoms. Based on these observations, our approach to staghorn stones has been modified with regard to stone and patient-related parameters, such as stone burden, upper urinary tract anatomy, stone composition, and patient compliance.
