Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Nephrolithiasis Management

Background:

  • Percutaneous nephrostolithotomy (PCNL) is a key procedure for kidney stone removal.
  • Traditional PCNL involves multiple steps for sheath and dilator insertion.
  • A novel 1-step percutaneous access sheath (NS) has been developed to streamline this process.

Purpose of the Study:

  • To evaluate the initial human experience and safety of the novel 1-step percutaneous access sheath (NS).
  • To assess the efficacy of the NS in facilitating renal access for percutaneous nephrostolithotomy.

Main Methods:

  • Retrospective review of 30 consecutive patients undergoing PCNL using the NS.
  • Data collected included patient demographics, operative parameters, recovery, and complications.

Related Experiment Videos

  • Analysis of stone burden, access location, operative time, blood loss, and hospital stay.

    • Main Results:

    • The NS facilitated successful renal access in all 30 patients.
    • Mean operative time was 114.8 minutes, with a mean estimated blood loss of 145.5 cc.
    • 76.7% of patients had no residual calculi post-procedure; no complications were related to the NS.

    Conclusions:

    • The novel 1-step renal access sheath (NS) is safe and easy to use.
    • The NS demonstrates potential advantages for percutaneous nephrostolithotomy compared to conventional sheaths.
    • This technique offers a promising advancement in kidney stone treatment.
