ABSTRACT

Objective To study the effect of extracellular matrix(ECM)of xenogenic femoral fascia which is a tissue-engineering material in repair of renal trauma.Methods Twenty-four experiment dogs were divided into 3 groups:group 1(n=10),the kidneys were repaired using ECM of xenogenic femoral fascia;group 2(n=10),the kidneys were repaired using self-omentum;group 3(n=4),xenogenic femoral fascia was used as repair materials.The animals were sacrificed separately at 1,2 weeks and 1,2,4 months after renal repair operations in group 1,2.In group 3,the animals were sacrificed separately at 2 weeks and 2 months after renal repair operations.The examinations of blood routine were performed before and after operations immediately,blood creatinine and serum renin were measured before operations and before death.The creatinine clearances of affected and contralateral normal kidneys were evaluated before death and the local areas of renal repair were studied by light and scan electron microscopy.Results In group 1,bleeding stopped rapidly and completely after the entire patch was sutured,only mild adhesions to surrounding tissues were found in various times after operations.As time passed,the repair patch was replaced by smooth neocapsule just like a normal one.In group 2,the bleeding volume in the operations was larger than the other 2 groups.It was diffieult tO separate the kidneys from the surrounding tissues.The wounds gradually contracted because of the scar forming.In group 3,there were severe immunological reactions in the patchs.Conclusion ECM of xenogenic femoral fascia is an ideal tissue-enginee rjng material for renal repair.
