Summary

The Ligasure vessel-sealing system significantly reduced blood loss and operative time during laparoscopic radical nephrectomy for renal-cell carcinoma compared to conventional methods. This advanced technology appears effective in complex laparoscopic surgeries.

Journal of endourology·2026

Area of Science:

  • Urology
  • Surgical Technology
  • Oncology

Background:

  • Laparoscopic surgery presents unique technical challenges.
  • Vessel-sealing technologies aim to address these challenges.
  • The Ligasure system is a novel bipolar radiofrequency generator for vessel sealing.

Purpose of the Study:

  • To compare the effectiveness of the Ligasure system against conventional methods.
  • To evaluate the Ligasure system in laparoscopic radical nephrectomy for renal-cell carcinoma.

Main Methods:

  • 30 patients with renal-cell carcinoma underwent laparoscopic radical nephrectomy.
  • Patients were randomized into two groups: conventional (15) and Ligasure system (15).
  • Key metrics analyzed included intraoperative blood loss, operative time, and conversion rates.

Main Results:

  • No significant differences in baseline characteristics or conversion rates between groups.
  • Ligasure group showed significantly lower mean intraoperative blood loss (100 mL vs. 485 mL).
  • Ligasure group demonstrated significantly reduced mean operative time (68 min vs. 164 min).

Conclusions:

  • The Ligasure system provides a reliable seal for vessels and tissue bundles.
  • It reduces operative time and blood loss by minimizing sutures and instrument exchanges.
  • This energy-based device is effective for advanced laparoscopic procedures.
