Purpose
I analysed the efficacy and safty of Extracorporeal Shock Wave Lithotripsy (ESWL) in patient with urinary tract calculi, using a Dornier Compact S^R lithotliptor.
Materials and method
I reviewed the records of all the patient who had urinary calculi and were treated by ESWL, between August 1, 1996 and August 1, 2001, retrospectively. The location and sizes of stones, session, success rate, and cause of failure and complications of ESWL were analysed. The definition of successful treatment was no calcification on the X-ray (plain film, KUB) or residual fragments ≤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. Total success rate was 94.3% (445/470), with success rates of 97.4%, 90.8%, 82.1% and 88.9% for stone sizes <10mm, 11-20mm, 21-30mm and >31mm, respectively.
Conclusion
The results shows 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 lithotriptor, capable of treating stones in the kidney and throughout the ureter.
