“…Efforts to augment or replace the bladder are old (1,2), and most commonly digestive tract segments were used for this purpose (3). Considering, however, the characteristics of intestinal mucosa, structurally and functionally distinct from the bladder, problems such as production of secretions, infection, electrolytic changes and even developing of tumors still await for a definitive solution (4).…”

Objective: To assess the value of the silicone modeler in preventing graft retraction in dogs undergoing bladder replacement with de-epithelialized ileum.Materials and Methods: Twelve female dogs underwent total cystectomy and bladder replacement by neobladder made of demucosalized ileal segment, comparing the group with modeler (group I) and the group without modeler (group II). Cystometry data, graft epithelization and radiological assessment (cystography and excretory urography) were analyzed.Results: Neobladder capacity, at 2 months, ranged from 50 to 250 mL (mean 191 mL) and from 5 to 60 mL (mean 22 mL) and at 6 months, from 60 to 270 mL (mean 202.5 mL) and from 5 to 75 mL (mean-30.5 mL), respectively in groups I and II, with a statistically significant difference between groups. After 30 days, postoperatively the presence of transitional epithelium was observed in all fragments obtained by biopsy.Conclusion: The use of the intravesical silicone modeler prevented the retraction of the neobladder of de-epithelialized ileum.

“…No such a complication has been reported in dogs in which a gastric segment was simply anastomosed to the bladder [17][18][19], Therefore, the gastric cuff facing the bladder wall must have eroded the bladder with its acid secretion. The pyloric glands in the stomach secrete mucus to protect the gastric mucosa from the digestive action of gastric juice.…”

Construction of a Continent Catheterizable Urinary Valve from a Gastric Segment in Dogs

We constructed a continent, catheterizable urinary valve from a gastric segment in 7 dogs. A vascularized gastric segment was isolated from the greater curvature and was tubularized. A cuff was made at the distal end of the tube. The gastric tube was anastomosed to the dome of the bladder with intussusception of the cuff portion into the bladder cavity. The valve provided continence over a wide range of bladder pressure. However, an ulcer of the bladder developed where the gastric mucosa of the cuff faced the bladder mucosa in 5 dogs, with a resultant intraperitoneal perforation in 2 dogs. The development of the bladder ulcer may be a serious complication of an anastomosis of an isolated gastric segment to the bladder.
