Summary

Low-frequency extracorporeal lithotripsy for kidney and ureteric stones is effective, especially for smaller stones. Repeat treatments can improve outcomes, and low frequencies avoid observed scarring from high-frequency methods.

Area of Science:

  • Urology
  • Nephrology

Context:

  • Extracorporeal lithotripsy (ECL) is a non-invasive treatment for kidney and ureteric stones.
  • Previous studies have explored various parameters affecting ECL efficacy and patient outcomes.

Purpose:

  • To evaluate the effectiveness and outcomes of low-frequency extracorporeal lithotripsy for renal and ureteric stones.
  • To assess the impact of stone size and repeat treatments on success rates.
  • To compare the incidence of scintigraphic scars between low and high-frequency lithotripsy.

Summary:

  • A total of 526 extracorporeal lithotripsy procedures were performed for renal and ureteric stones.
  • Low-frequency ECL (1.25-2.5 Hz) was administered without anesthesia in 85% of cases.
  • Success rates were 55%, with partial results in 22.5% and failures in 22.5%. Best outcomes were observed for stones <20 mm. Repeat sessions improved results. Low-frequency ECL did not result in observed scintigraphic scars, unlike high-frequency methods.

Impact:

  • Low-frequency extracorporeal lithotripsy offers a viable, often anesthesia-free treatment option for kidney and ureteric stones.
  • Optimal patient selection (smaller stones) and consideration for repeat sessions can enhance treatment success.
  • The findings suggest low-frequency ECL may be preferable to minimize potential renal scarring.
