Stepwise shock wave lithotripsy: Results of initial study for the treatment of urinary stones in childhood

Abstract

Stepwise shock wave lithotripsy was an effective procedure for the treatment of urinary calculi in childhood.

Pediatric urolithiasis: an 8-year experience of single centre

“…Extracorporeal shock wave lithotripsy has been demonstrated to be effective and safe for the treatment of pediatric urolithiasis [27,28]. This treatment modality neither causes renal scars nor affects renal function and linear growth [29].…”

Comparison of Conventional and Step-Wise Shockwave Lithotripsy in Management of Urinary Calculi

“…4 To our knowledge, our randomized trial is the first to examine the impact of step-wise increase of output voltage during SWL on outcome in humans. We studied whether a stepwise increase in output energy during SWL yielded a better success rate than constant output of energy during SWL without increased morbidity.…”

“…3 Step-wise SWL was effective in the management of urinary calculi in 31 children without increased morbidity and with acceptable success rates. 4 In our clinical study, we aimed to compare the results of conventional and step-wise SWL procedures in the management of urinary calculi. stones were detected by plain radiography of the kidneys, ureters and bladder, urinary system ultrasonography, and intravenous urography.…”

Effect of output voltage distribution on stone comminution efficiency during shockwave lithotripsy in renal or ureteropelvic junction stones: A preliminary study

“…Demirci et al [7,8] have reported similar results in clinical studies. They suggested that increasing the intensity of shockwaves could compensate for the screening effect, a phenomenon whereby shockwaves are scattered and attenuated by fragmented stone powders accumulating around residual large pieces.…”
