The Master Lithoclast device demonstrated effective stone clearance during simultaneous bilateral Percutaneous Nephrolithotomy (PCNL). This lithotripsy method proved efficient and safe for patients with kidney stones.
Area of Science:
- Urology
- Surgical Technology
Background:
- Percutaneous Nephrolithotomy (PCNL) is a common procedure for kidney stone removal.
- Evaluating novel devices for improved efficiency and safety in PCNL is crucial.
Purpose of the Study:
- To assess the efficacy of the Master Lithoclast (trilogy lithoclast) in simultaneous bilateral PCNL.
- To determine operative time and stone clearance rates using this device.
Main Methods:
- Prospective case series of 40 patients undergoing simultaneous bilateral PCNL.
- Patients were categorized using Guy's stone scoring system.
- Operative time and stone clearance were recorded.
Main Results:
- Complete stone clearance was achieved in 75% of patients.
- The average operative time was 74.8 minutes.
- The Master Lithoclast showed effectiveness regardless of stone composition.
Conclusions:
- Master Lithoclast facilitates faster stone clearance in PCNL.
- The device offers ease of use, tissue safety, and reduced fragment obstruction.
- This technology represents a promising advancement in kidney stone treatment.
