Mini-PCNL using the new Cyber Ho with Magneto technology versus thulium fiber laser: are there any differences?

Area of Science:

• Urology
• Medical Technology
• Nephrolithiasis Treatment

Background:

• Percutaneous nephrolithotripsy (PCNL) is a key procedure for kidney stone removal.
• Advancements in laser technology aim to improve the safety and efficacy of PCNL.
• Comparing different laser systems is crucial for optimizing stone treatment.

Purpose of the Study:

• To compare the safety and efficacy of Holmium: YAG Cyber Ho generator with Magneto pulse modulation technology against Thulium Fiber Laser (TFL).
• To evaluate these lasers in mini-percutaneous nephrolithotripsy (Mini-PCNL) for renal stones measuring 10-20 mm.

Main Methods:

• A comparative study involving 100 patients undergoing Mini-PCNL.
• Group A utilized Thulium Fiber Laser (TFL) Fiber Dust generator; Group B used Holmium: YAG Cyber Ho generator with Magneto technology.
• Standardized Mini-PCNL techniques were employed, with laser settings adjusted for stone characteristics.

Main Results:

• Both laser systems demonstrated comparable stone-free rates (SFR) and complication profiles.
• The Magneto group showed significantly lower mean delivered energy and energy consumption per volume ablated (p<0.05).
• While not statistically significant, the Magneto group exhibited a higher ablation speed and more frequent complete dusting.

Conclusions:

• The Holmium: YAG Cyber Ho generator with Magneto technology is a safe and effective alternative to TFL for treating renal stones up to 20 mm.
• Magneto technology presents advantages in dusting efficiency, requiring less energy and potentially offering faster ablation.
• Further research may confirm the statistical significance of observed efficiency gains.
