Abstract
Porcine ureters were anastomosed using an albumin stent and diode laser in vitro. The albumin stent provided precise apposition for an end to end anastomosis and enhanced welding strength. The anastomosis seam was lasered with an 810 nm diode laser using continuous wave and pulse light through a hand-held 600 micrometer noncontact optical fiber. Tensile strength, burst pressures, operative times, total energy and thermal damaged were measured in this study. The results demonstrated that using an albumin stent to laser weld ureteral anastomoses produces strong weld strengths. The liquid albumin solder also provided satisfactory welding strength. There were no significant differences of tissue thermal damage between the albumin stent alone, liquid solder alone and both combination groups. Thermal damage to tissue depended on laser setting and energy. This study determined the appropriate laser setting parameters to perform in vivo ureteral end to end anastomosis.
