Abstract

One future use of laparoscopic technology is in extravesical reimplantation of the ureters. Technical difficulty arises, however, when intracorporal fine suturing is necessary. We have assessed the efficacy of laser-activated fibrinogen solder to close vesical muscle flaps over submucosal ureters (Lich-Gregoir technique) in a canine model. Four dogs were subjected to unilateral flap closures via a protein solder consisting of indocyanine green and fibrinogen applied to the serosal surface of the bladder and exposed to 808 nm continuous wave diode laser energy. Contralateral reimplantation was performed using 4 - 0 vicryl muscle flap closures and served as controls. Urinary drainage catheters were left in place for 24 hours postoperatively. At 7 (n = 1), 14 (n = 2), and 28 (n = 1) days following reimplantation, intravenous pyelograms confirmed bilateral renal function and ureteral patency. Disruption of wound closures were considered the point of wound dehiscence, vesical diverticulum, or leakage. At intravesical pressures above 100 cm H2O there was no evidence of wound disruption in either of the groups. However, surrounding normal tissue was noted to disrupt. In conclusion, laser-welded vesical wound closures appear at least as strong as suture closures in the canine model.
