Summary

A new single-step device for percutaneous nephrolithotomy significantly reduces insertion time for renal access. This novel Pathway Access Sheath (PAS) offers a safe and effective alternative to traditional two-step methods.

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Medical Device Technology

Background:

  • Percutaneous nephrolithotomy (PCNL) is the gold standard for large renal calculi.
  • Traditional PCNL access involves a two-step dilation process, which can be time-consuming.
  • A novel single-step device, the Pathway Access Sheath (PAS), has been developed to simplify PCNL access.

Purpose of the Study:

  • To evaluate the safety and efficacy of the novel Pathway Access Sheath (PAS) for percutaneous nephrolithotomy.
  • To compare the insertion time, blood loss, and cost of the PAS versus standard two-step access methods.
  • To assess the potential of PAS to become a new standard for renal access.

Main Methods:

  • A randomized study comparing two groups of patients undergoing PCNL.

  • Group 1 (10 patients): Standard two-step access using a high-pressure balloon catheter.
  • Group 2 (11 patients): Novel single-step Pathway Access Sheath (PAS).

    • Main Results:

    • The PAS group demonstrated a statistically significant shorter average insertion time (3 minutes) compared to the high-pressure balloon catheter group (5 minutes, 42 seconds; P <0.01).
    • Estimated blood loss and cost were comparable between the two techniques.
    • The PAS's sheath flexibility was identified as a beneficial feature in certain cases.

    Conclusions:

    • The novel single-step Pathway Access Sheath (PAS) is a safe and effective device for percutaneous nephrolithotomy.
    • PAS significantly reduces the time required for renal access.
    • Further research is needed to determine if PAS will establish a new standard in renal access procedures.
