Abstract:
In situ extracorporeal shock wave lithotripsy(ESWL) monotherapy was performed in 75 cases with ureteral stones using the Modulith SL 20 electromagnetic lithotriptor between December 1990 and July 1991. The results obtained were as follows: 1. The locations of stones were upper ureter in 36 (48%) cases, midureter in 4 (5.3%) and lower ureter in 35 (46.7%). 2. The average number of ESWL was 1.27 sessions. 3. The number of ESWL sessions increased in accordance with increment of stone size. 4. The success rate was 97.2% in upper ureteral. 100% in midureteral, and 97.1% in lower ureteral stones. 5. The final success rate according to stone size was not significantly different. 6. Success rate decreased relatively in cases of complete ureteral obstruction by stones. Therefore, in situ ESWL monotherapy is considered to be a convenient safe, and efficient procedure as the first applicable method for the treatment of all ureteral stones regardless of stone size and location, because the multiple repeated ESWL monotherapy increases the success rate without ureteral deterioration.
