Abstract:
PURPOSE: Shock Wave Lithotripsy (SWL) has revolutionized the management of urinary stones. However, exceptions and complications have occasionally been observed. Therefore, we evaluated the success rate, indications, complications and clinical characteristics of 5,000 patients that treated with SWL. MATERIALS AND METHODS: We evaluated 5,000 patients were a SWL was performed using the EDAP LT01 and 02 piezoelectric lithotriptors, between 1987 and 2001. The study group comprised of 2,942 men and 2,058 women (1.43:1) with a mean age of 46.7 years. We evaluated the success rate of the SWL by the sizes and locations of the stones and by treatment sessions. RESULTS: The total success rate of the SWL was 91.5%. For renal stones, the success rates ranged from 95.9, for stones 0.5-1.0cm in size, to 60.0%, for stones 1.6-2.0cm in size. For upper ureter stones, the success rates ranged from 87.1, for stones 0.5-1.0cm in size, to 54.5%, for stones 1.6-2.0cm in size. For lower ureter stones, regardless of stone size, the SWL was 100% successful. The mean success rate was 99.3%. With the complications, gross hematuria was observed, with septicemia in 10 patients. CONCLUSIONS: The success rate of SWL was 91.5%. In our 14 years of experience, SWL has proved to be an effective and safe method to treat the urinary stones.
