    Percutaneous nephrolithotomy (PCNL) is the standard treatment for large renal stones but carries risks of severe bleeding.

  • 2

    Conventional sharp needles used in PCNL can injure renal vessels, leading to complications such as arterial embolization.

  • 3

    A novel blunt needle design aims to reduce the risk of arterial injuries during renal puncture in PCNL procedures.

  • 4

    Research involved analyzing embolization cases to identify at-risk arteries and testing the blunt needle's effectiveness in ex vivo models.

  • 5

    The study demonstrated that the blunt needle significantly reduced arterial injuries compared to conventional needles during renal access.
