Morphologic changes in the canine urinary tract after ureteral reconstruction with the tunica albuginea (experimental study)*

Abstract

(1) The success of reconstructive procedures in the ureters can be achieved if the continuity of the ureter is preserved and the catheter is removed after 14 days. (2) The substitution of a complete ureteral loss with a tube-graft of the tunica albuginea results in necrosis of the graft and restenosis.

Avaliação morfofuncional do enxerto de túnica albugínea suína na cistoplastia em ratos

“…Gadja et al(2006) utilizaram retalhos de túnica albugínea na reconstrução do ureter de cães e observaram bons resultados na substituição de parte do órgão. O uso da túnica albugínea como biomaterial mostrou-se vantajoso por ser um tecido de fácil obtenção, processamento e aplicação (Nunes, 2007).…”

Tissue Engineering and Ureter Regeneration: Is it Possible?

“…One ureter was regenerated with preservation of ureter continuity and a second on the entire ureter length (2–3.5 cm). Ureter regeneration occurred only when continuity of ureter was preserved; substitution of complete ureteral loss with tube-graft resulted in necrosis and restenosis (124). Regeneration of the ureter segment is possible only when ureteral continuity is maintained.…”
