Summary
The Lithoring multi-one lithotripter effectively treats urinary stones with a 97.9% disintegration rate and 83.3% stone-free rate after 3 months, even without anesthesia. This new technology shows comparable side effects to existing spark gap lithotripters.
Area of Science:
- Urology
- Medical Devices
- Nephrology
Context:
- The Lithoring multi-one is a novel spark gap lithotripter developed in Italy.
- It features a tunable power generator, integrated fluoroscopy and ultrasound localization, and an isocentric shock wave window.
- The device is designed for treating both urinary and biliary stones.
Purpose:
- To evaluate the experimental and clinical efficacy of the Lithoring multi-one lithotripter.
- To assess the device's performance in vitro, in vivo (pigs), and in clinical trials for urinary stone treatment.
Summary:
- Experimental studies included in vitro analysis and in vivo trials on pigs, showing favorable side effect rates compared to other spark gap lithotripters.
- Clinical experience with 50 patients treated for urinary stones (including large, ureteral, and staghorn calculi) demonstrated a 97.9% disintegration rate.
- Patients received an average of 1700 shock waves at 19.2 Kv without anesthesia, achieving an 83.3% stone-free rate at 3 months with no complications.
Impact:
- The Lithoring multi-one offers a promising alternative for urinary stone management, potentially reducing the need for anesthesia.
- Its high disintegration and stone-free rates suggest significant clinical utility.
- The comparable side effect profile indicates a favorable safety margin for this new lithotripter.
