    Author: Ibrahim ME, Ezzat MM, Ezzat WM.
    Journal: Int Urol Nephrol; 2010 Sep; 42(3):697-701. PubMed ID: 20013053.
    Abstract:
    PURPOSE: To assess the capability of urothelium to proliferate, creep and line the inner surface of the interposed seromuscular tapered ileal tube. MATERIALS AND METHODS: Under general anesthesia, 15 female dogs underwent resection of 5 cm of the mid ureter and replaced with tapered seromuscular ileal tube stented for 6 weeks. The animals were sacrificed, and cross section of the ileal ureters were examined histologically for the lining cells. RESULTS: Multilayer of transitional epithelium was seen covering all the inner surface of the interposed seromuscular tube at the end of 6 weeks. Excessive inflammatory cell infiltration was a prominent finding in the submucosal layer. CONCLUSION: Transitional epithelium has the capability to proliferate, grow and cover the inner surface of the interposed seromuscular ileal tube. Urothelium lining avoid the metabolic complications of the intestinal mucosa.
