Laparoscopic laser soldering for repair of ureteropelvic junction obstruction in the porcine model. Academic Article uri icon

abstract

  • Background and Purpose: Laparoscopic pyeloplasty is used for the repair of ureteropelvic junction (UPJ) obstruction. Our objective was to introduce laser soldering to this procedure. Materials and Methods: We developed a system based on a CO2 laser, an infrared detector, and two infrared transmitting optical fibers to obtain temperature-controlled laser soldering of cuts in tissues. The system was used for laparoscopic soldering of incisions in the kidneys of pigs. Results: We carried out laparoscopic pyeloplasty successfully in a porcine model using fiberoptic laser soldering. Laparoscopic laser soldering was found to be faster than suturing. It was easier to use and provided watertight bonding. Conclusions: This technique will be useful in pyeloplasty as well as other laparoscopic surgical procedures.
