Abstract

Purpose
We analyzed the efficacy and safety of extracorporeal shock wave lithotripsy (ESWL) for treating patient with urinary tract calculi with using a Dornier Compact S(R)lithotriptor.
Materials and Methods
We retrospectively reviewed the records of all the patient who had urinary calculi and who were treated by ESWL between August 1, 1996 and August 1, 2001. The location and sizes of the stones, the number of sessions, the success rate, the causes of failure and the complications of ESWL were analyzed. The definition of successful treatment was no calcification on the X-ray (plain film, KUB) or residual fragments < or= 3mm in size.
Results
Of the 470 cases, there were 157 (33.4%) and 313 (66.6%) cases of renal stones and ureteral stones, respectively. The total success rate was 94.3% (445/470), with success rates of 97.4%, 90.8%, 82.1% and 88.9% for stone sized <10mm, 11-20mm, 21-30mm and >31mm, respectively.
Conclusions
The results showed that ESWL is a highly effective and minimally invasive treatment modality as the 1st therapeutic option for urinary stones. The Dornier Compact S(R)is an efficient and safe lithotripter that's capable of treating stones in the kidney and throughout the ureter.
