[Clinical studies on treatment by ESWL using EDAP LT-02 for upper urinary tract calculi].
From July 1993 through March 1994, 512 ESWL therapy was performed on upper urinary tract calculi in 277 renoureteral units using an EDAP LT-02 Lithotripter. Of these cases, 244 renoureteral units which were followed up for more than 3 months after ESWL were examined. These included 124 renal stones and 100 ureteral stones. Complete removal or sufficient stone disintegration was obtained in 66.7, 98.0 and 94.1% in the R1, R2 and R3 groups of renal stones, respectively, and in 92.4, 87.5 and 100% in the U1, U2 and U3 groups of ureteral stones, respectively. The over-all stone-free and success rates were 78.2 and 95.2%, respectively for renal stones and 93.0% and 94.0% respectively for ureteral stones. These results were better than those obtained by LT-01 in our experiences. The newly built-in coaxial X-ray system greatly contributed to these high success rates. As side effects, there were no serious complications. It is concluded that ESWL using an EDAP LT-02 is safer and more effective for the treatment of upper urinary tract calculi.
