Laser tissue welding with albumin effectively controlled bleeding and sealed the kidney during laparoscopic partial nephrectomy in pigs. This technique offers a promising solution for hemostasis in kidney surgery.

Area of Science:

  • Urology
  • Surgical Innovation
  • Biomaterials

Background:

  • Laparoscopic partial nephrectomy is widely used but limited by hemostasis challenges.
  • Achieving reliable hemostasis and sealing the collecting system remains a hurdle in minimally invasive kidney surgery.

Purpose of the Study:

  • To evaluate laser tissue welding using human albumin as a solder for hemostasis and collecting system closure.
  • To assess the safety and efficacy of this technique during laparoscopic heminephrectomy in a porcine model.

Main Methods:

  • Laparoscopic heminephrectomy was performed in pigs, with laser tissue welding using an albumin-indocyanine green solder applied to the renal parenchyma.
  • Procedures involved hilar vessel occlusion, laser application (810-nm pulsed diode laser), and subsequent evaluation via retrograde pyelograms and histopathology.

Main Results:

  • All procedures were completed without complications, demonstrating effective hemostasis and collecting system seal.
  • Mean operative time was 82 minutes with an average blood loss of 43.5 mL; retrograde pyelograms showed no extravasation in most kidneys.
  • Histopathology confirmed preservation of renal parenchyma beneath the welded solder.

Conclusions:

  • Laser tissue welding with albumin provides reliable hemostasis and seals the collecting system during laparoscopic heminephrectomy.
  • The technique protects the underlying renal parenchyma from thermal damage, offering a safe and effective method for kidney surgery.
