Clinical Experience of Extracorporeal Shock Wave Lithotripsy for Urinary Calculi / 대한비뇨기과학회지

ABSTRACT

Extracorporeal shock wave lithotripsy (ESWL) is a non-contact, non-invasive technique for disintegrating urinary tract calculi into sand-sized particles which can be passed spontaneously by a patient during normal urine flow. ESWL with an Edap lithotriptor which uses piezoelectric elements, was performed in 465 cases with urinary calculi from May 1987 to October 1988. The overall success rate of ESWL in 465 cases was 92.7% and renal stones were more successfully (95.9%) treated than ureteral stone (86.7%) main complications of ESWL for urinary calculi were hematuria (70.8%), hypertension(8.0 %). renal colic (2.6%), ileus (2.5%) and fever (1.2%) and then they were controlled without specific treatment. ESWL using ultrasonic localization was effective for treatment of the urinary stones.
