New monofilament basket for bladder calculi.

Area of Science:

• Urological devices
• Minimally invasive surgery

Background:

• Traditional stone retrieval baskets have limitations.
• Need for improved devices in urology and biliary interventions.

Purpose of the Study:

• Evaluate a new monofilament basket for stone manipulation.
• Compare its efficacy and safety against existing baskets.

Main Methods:

• Experimental testing and clinical application of the monofilament basket.
• Assessment of key performance metrics and safety parameters.

Main Results:

• The monofilament basket demonstrated successful stone manipulation in both experimental and patient settings.
• Key advantages observed include in vivo adjustability, reduced mucosal trauma, irrigation/aspiration capability, and compatibility with lithotriptor electrodes.

Conclusions:

• The new monofilament basket represents a significant advancement in stone retrieval technology.
• Potential applications extend to ureteral, renal pelvis, and biliary tree interventions.
