Does a Slower Treatment Rate Impact the Efficacy of Extracorporeal Shock Wave Lithotripsy for Solitary Kidney or Ureteral Stones?

For solitary renal stones between 1 and 2 cm an SR results in a better treatment outcome than an FR for ESWL. However, when stone size is less than 1 cm, SFR differences in the SR and FR treatment groups become less significant.
