Effectiveness and safety of the Dornier compact lithotriptor: an evaluative multicenter study

Area of Science:

• Urology
• Medical Devices
• Nephrology

Background:

• Renal stones pose a significant health burden requiring effective treatment.
• Extracorporeal shock wave lithotripsy (ESWL) is a common modality for kidney stone management.
• Advancements in lithotriptor technology aim to improve efficacy, safety, and portability.

Purpose of the Study:

• To evaluate the efficacy and safety of the Dornier compact lithotriptor for managing renal stones.
• To assess the treatment success rate and complication profile of this mobile ESWL device.

Main Methods:

• 191 treatments were administered to 169 patients with renal stones.
• The Dornier Compact lithotriptor, a mobile, ultrasound-guided device with an electromagnetic energy source, was utilized.
• Patients received combined parenteral sedation and analgesia during treatment.

Main Results:

• A stone-free rate of 72.8% was achieved, with 15.4% having small fragments (<4 mm).
• Adverse effects were predominantly mild to moderate, including pain (39%) and nausea/vomiting (14%).
• The device's mobility, user-friendliness, and lower cost were noted advantages.

Conclusions:

• The Dornier compact lithotriptor is an effective and safe option for renal stone management.
• Its performance is comparable to larger, stationary lithotripsy devices.
• The mobile nature and cost-effectiveness of this device offer significant clinical benefits.
