biostudies-literatureUnknown10(4)Soria F<h4>Background</h4>We assessed an antireflux biodegradable heparin-coated ureteral stent (BraidStent^®-H) in an animal model comparative study after endoscopic treatment of ureteral strictures.<h4>Methods</h4>A total of 24 female pigs underwent initial endoscopic, nephrosonographic, and contrast fluoroscopy assessment of the urinary tract. Afterward, unilateral laparoscopic ureteral stricture model was performed. Three weeks later, the animals underwent laser endoureterotomy and were randomly assigned to Group-I, in which a double-pigtail stent was placed for 6 weeks, or Group-II, in which a BraidStent®-H was placed. Follow-up was carried out by ultrasonography, contrast fluoroscopy, ureteroscopy, urinalysis and bacteriuria assessment at 3, 6, 12 and 5 months.
