چکیده

Background and Objectives: We compared ureteral anastomosis using a laser and intraluminal albumin stent with both conventional suturing and laser soldering techniques. Study Design/Materials and Methods: Twelve pigs underwent bilateral ureteral anastomoses (N1⁄4 24) using one of the three anastomotic methods: (1) laser welding with intraluminal albumin stent (N1⁄4 11); (2) with albumin solder (N1⁄4 8); and (3) conventional suturing (N1⁄4 5). Operative parameters, leakage rate, intrapelvic perfusion pressure, urography, and histology of the anastomoses were examined. Results: Operative time for ureteral anastomosis in the stent and solder groups were significantly shorter than the suture group (means 370 seconds and 360 vs. 710 seconds, both P1⁄4 0.02). Leakage rate of the anastomoses was lower in the stent group (9%, 1/11) as compared to the solder group (25%, 2/8). The Whitaker test showed that the intrapelvic perfusion pressure elevated gradually after anastomosis and significantly increased at 4 weeks postoperatively in all three methods. Various degrees of hydronephrosis were also noticed in three groups after 4 weeks of surgery. Conclusions: Use of the intraluminal albumin stent increased the reliability of laser welding for ureteral anastomosis. The clinical significance of using this technique should be investigated further. Lasers Surg. Med. 32:294–298, 2003. 2003 Wiley-Liss, Inc.

Intraluminal albumin stent assisted laser welding for ureteral anastomosis.

BACKGROUND AND OBJECTIVES The success of laser tissue welding or soldering depends on optimal laser settings, solder material, and tissue type and geometry. To develop a practical laser welding technique for ureteral repair, an intraluminal albumin stent was designed to enhance the welding effects on ureteral end to end anastomosis. STUDY DESIGN/MATERIALS AND METHODS In vitro porcine ureters ...

Laser Welding with an Albumin Stent: Experimental Ureteral End to End Anastomosis

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 μm noncontact optical fiber. Tensile strength, burst pressures, operative times, total...

Sutureless End to End Ureteral Anastomosis Using a New Albumin Stent and Diode Laser

Sutureless end to end ureteral anastomoses was successfully constructed in acute and chronic experiments. A photothermal sensitive hydrolyzable (PSH) albumin stent played roles as solder and intraluminal supporter to adhesion and position the anastomosed ureter by end to end fashion. The anastomosis seam was lased with 810 nm diode laser energy supplied through hand-held 600 mm noncontact optic...

Laser-assisted vascular end to end anastomosis of elastin heterograft to carotid artery with an albumin stent: a preliminary in vivo study.

BACKGROUND AND OBJECTIVES Laser-assisted end to end vascular anastomosis of an elastin heterograft to native artery may prevent problems associated with currently available vascular synthetic grafts and conventional suture anastomosis. STUDY DESIGN/MATERIALS AND METHODS A total of 21 anastomoses in the carotid arteries of 7 domestic swine were performed with an 800 nm laser and an albumin ste...
