This study demonstrates the feasibility of using a CO2 laser delivered via a flexible fiber for laparoscopic partial nephrectomy (LPN) in pigs. The novel technique achieved precise cutting and effective hemostasis with minimal damage, suggesting potential benefits for kidney surgery.

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Surgical Technology

Background:

  • Laparoscopic partial nephrectomy (LPN) demands precise cutting and hemostasis under warm ischemia.
  • Current LPN techniques face challenges in achieving optimal tissue manipulation and minimizing blood loss.

Purpose of the Study:

  • To evaluate the feasibility of performing LPN using CO2 laser energy transmitted through a flexible optical fiber.
  • To assess the efficacy of this novel laser technique for renal mass resection and hemostasis in an animal model.

Main Methods:

  • CO2 laser energy (45W, 100mJ/pulse) was delivered via a flexible fiber for partial nephrectomy in 7 farm pigs.
  • Renal portions were excised, and the collecting system was sutured; laser pulses were used for bleeding points.
  • Animals were observed for 3 weeks post-surgery before necropsy and histological examination.

Main Results:

  • The CO2 laser enabled sharp renal cutting with minimal charring and blood loss (<10cc) for an average of 18% of kidney mass removed.
  • No significant peritoneal or retroperitoneal abnormalities were observed during necropsy.
  • Histological analysis revealed minimal coagulation necrosis (up to 100 µm) at the incision site.

Conclusions:

  • This study presents the first use of a CO2 laser via a flexible fiber for LPN in an animal model.
  • The technique demonstrated excellent parenchymal incision and hemostasis with minimal adjacent tissue damage.
  • Further research is warranted to compare this laser-based approach with standard LPN techniques for clinical application.
