This study shows the novel Simon clamp effectively performs laparoscopic partial nephrectomy, enabling safe tumor removal and kidney repair with minimal bleeding and no complications in three patients.

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Nephrology

Background:

  • Partial nephrectomy is the gold standard for small renal masses.
  • Laparoscopic partial nephrectomy offers benefits but requires precise control of renal blood flow.
  • Selective parenchymal clamping is crucial for minimizing ischemia and complications.

Purpose of the Study:

  • To evaluate the initial clinical experience with a novel laparoscopic clamp for selective parenchymal clamping during partial nephrectomy.
  • To assess the safety and efficacy of the Simon clamp in three laparoscopic partial nephrectomy cases.

Main Methods:

  • Three laparoscopic partial nephrectomies were performed using the Simon clamp.
  • Patients had lower pole renal tumors ranging from 2 to 2.4 cm.

Published on: July 8, 2025

  • Demographic data, operative time, blood loss, and warm ischemia time were recorded.

    • Main Results:

    • Mean operative time was 100 minutes, with mean blood loss of 16 ml.
    • Mean warm ischemia time was 33 minutes.
    • All patients were discharged on postoperative day 2 with negative surgical margins and no complications.

    Conclusions:

    • The Simon clamp facilitates effective tumor resection and renal defect repair during laparoscopic partial nephrectomy.
    • This novel instrument allows for precise clamping, preventing collateral renal injury.
    • Further development of instruments for selective clamping in various tumor locations is anticipated.
