Shock Wave Lithotripsy Using Fluoroscopic Versus Ultrasonic Localization

Shock Wave Lithotripsy Using Fluoroscopic Versus Ultrasonic Localization for Pediatric Renal Stones.

Epidemiological studies have shown a progressive increase in the incidence of pediatric urolithiasis over the past few decades.

Pediatric stone disease is considered endemic in developing nations including Turkey, Pakistan, and eastern countries. The introduction of SWL by Chaussy et al. in the early 1980s revolutionized the management of upper urinary tract calculus disease.

Reports of successful SWL in children were first published in 1986; then several reports showed safety, and stone-free rates comparable with those of adults. For successful SWL, accurate localization of the shock waves is performed by ultrasound (US) or fluoroscope (FS) to fully focus the shock waves on the stone
