Chronic renal insufficiency is a prelude to the majority of renal allograft dysfunction, although new immunosuppressant and infection prevention measures of the application, make acute renal graft loss decreased significantly, but the long-term graft loss has not improved, the main risk factors in renal transplant patients: due to cardiovascular disease, malignant tumor, infection and death and chronic renal allograft dysfunction leads to graft loss.
There are a number of factors that cause chronic kidney failure.
1,Type of donor (living or corpse);
2,Long absence of cold and heat;
3,In the past, there has been an acute rejection of rejection;
4, the late stage of chronic rejection;
5,Recurrence of primary glomerular disease;
6,Postoperative renal delay recovery;
7,BK virus associated nephropathy;
8,Transplanting renal doppler ultrasonography, vascular resistance index (R I) > 0.80;
10, the histocompatibility antigen pairing does not meet, the group reactive antibody level rises;
12,The patient has a poor adherence to sex and treatment is not compliant;
13,The transplantation of renal artery stenosis;
14,The transplantation of renal urinary tract obstruction;
15,The obstruction of the urinary tract by the recipient;
All of these cases can cause chronic kidney failure, so it is important to identify these reasons for the protection of kidney function. For a number of reasons, a kidney biopsy is clearly needed, so a kidney biopsy is important. Only through examination, and even a kidney biopsy can be diagnosed, and treatment can be achieved to extend the duration of the kidney transplant.
