Summary
Extracorporeal shock wave lithotripsy (ESWL) effectively treated kidney and ureter stones in 751 patients. High stone-free rates were achieved with minimal discomfort, allowing for widespread outpatient treatment.
Area of Science:
- Urology
- Nephrology
- Medical Technology
Background:
- Shock wave lithotripsy (SWL) is a common treatment for kidney and ureter stones.
- The EDAP LT-01 device was utilized for SWL procedures between 1988 and 1990.
- Patient stone characteristics and treatment outcomes require evaluation.
Purpose of the Study:
- To assess the efficacy and patient experience of ESWL using the EDAP LT-01 device.
- To evaluate treatment outcomes for both renal and ureteric stones.
- To determine the feasibility of outpatient ESWL treatment.
Main Methods:
- Retrospective analysis of 751 patients treated with EDAP LT-01 lithotripsy.
- Patients included those with renal stones (n=608) and ureteric stones (n=143).
- Ureteric stones were often repositioned to the kidney prior to treatment; double J-stents used for stones >15mm.
Main Results:
- 66% of renal stone patients were stone-free post-ESWL monotherapy; 5% required auxiliary procedures.
- 14% of renal stone patients retained fragments ≤4mm.
- 95% of ureteric stones (mobilized to kidney) were cleared by ESWL, with 74% treated as outpatients.
Conclusions:
- ESWL with EDAP LT-01 demonstrates high efficacy for renal and ureteric stones.
- The procedure is well-tolerated, requiring minimal analgesia or anesthesia, facilitating outpatient management.
- ESWL is a safe and effective treatment option for a significant majority of patients with kidney and ureter stones.
