    Abstract:
    OBJECTIVE: The aim of the study was to determine the effectiveness of extracorporeal shock wave lithotripsy(ESWL) therapy for renal calculi. METHODS: 126 patients were treated with Shanghai HX-902 lithotriptor on an inpatient basis. The stone size varied from 0.5 to 2.5 cm. Some patients had a double-J stent inserted prior to treatment. RESULTS: The overall stone-free rate in 2 months was 45.6%, whereas it was 53.3%, 40.8% and 18.1% according to the stone size, < or = 0.8, 0.9-1.9 and > or = 2 cm, respectively. Complications were rare, including 1 subcapsular hematoma formation, 15 renal colics and 5 stone streets, which were managed by conservative treatment or ureteral stenting or additional ESWL and resulted in complete stone clearance. CONCLUSION: ESWL therapy is a reasonable and effective method for renal stone, percutaneous nephrolithotripsy(PCNL) or open surgery should be considered for stones larger than 2 cm.
