Laparoscopic nephron sparing surgery (NSS) techniques, with and without ischemia, were evaluated over ten years. Both approaches demonstrated no tumor recurrence, indicating their effectiveness for complex kidney tumors.

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Oncology

Background:

  • Nephron sparing surgery (NSS) is crucial for preserving renal function in patients with kidney tumors.
  • Laparoscopic techniques have advanced, offering less invasive options for NSS.
  • A decade of experience provides valuable insights into the evolution and outcomes of laparoscopic NSS.

Purpose of the Study:

  • To present the institutional experience with laparoscopic nephron sparing surgery (NSS) over a ten-year period.
  • To compare outcomes of NSS performed with and without renal ischemia.
  • To analyze the evolution of surgical techniques and their impact on patient results.

Main Methods:

  • A retrospective review of 78 patients who underwent laparoscopic NSS between 1994 and the study period.

  • Patients were divided into two groups: partial nephrectomy without ischemia (Group 1, n=29) and with ischemia (Group 2, n=49).
  • Group 2 included cold ischemia (n=24) and warm ischemia (n=25); surgical techniques and reconstruction methods evolved during the study.

    • Main Results:

    • Mean operative time was 162 minutes for Group 1 and 216 minutes for Group 2.
    • Mean ischemia times were 44.9 minutes (cold) and 33.8 minutes (warm).
    • No tumor recurrence was observed at a mean follow-up of 23.9 months (Group 1) and 12.2 months (Group 2), with an acceptable complication rate.

    Conclusions:

    • Laparoscopic NSS, utilizing both warm and cold ischemia, expands indications for complex renal tumors.
    • The study demonstrates the feasibility and safety of laparoscopic NSS with effective renal reconstruction.
    • Long-term oncological control was achieved, supporting the role of laparoscopic NSS in kidney cancer management.
