ABSTRACT
Objective To study long term renal function of Donation after citizen's deceased transplantation.Methods We compared the data of 38 subjects who got Delayed Graft Function(DGF) with 80 Immediate Graft Function (IGF) subjects underwent DCD transplantation in our hospital before June 2016.Evaluated the renal function by detecting the serum creatinine (sCr),the estimating glomerular filtration rate (eGFR) calculated with MDRD formula and urine protein at the 1,2,3 year post transplantation.Results Analyzed the serum eGFR of two groups,there was no significant differences at 1 and 2 year post transplantation,sCr of two groups showed no significant differences at 3 year (P =0.053)post transplantation,eGFR of two groups showed significant differences at 3 year (P =0.042)post transplantation and positive incidence of urine protein showed significant differences at 2 year (P =0.028)and 3 year (P =0.037)post transplantation.Conclusion DGFoccuring after DCD transplantation had an effect on long term renal function,.mainly on reducing of eGFR and increasing of urine protein positive rate 2 or 3 years after transplant.
ABSTRACT
Objective To investigate the clinical value of color Doppler flow imaging (CDFI) for evaluating transplant renal artery stenosis (TRAS).Methods Clinical and ultrasonographic data of 216 kidney transplant recipients were collected by follow-up monitoring from September 2015 to July 2016.CDFI indexes included the peak systolic velocity (PSV) in the renal artery and resistant index (RI).Renal artery PSV and RI were measured.All suspected TRAS patients accepted transplant renal artery angiography (DSA).Results Fourteen patients with suspected TRAS accepted DSA,of which 12 patients were confirmed.The diagnostic accuracy of CDFI was 85.7％.When the POST-PSV ratio＞ 1 0,the sensitivity and specificity of diagnosis of TRAS were 91 ％ and 95 ％,respectively.CDFI indexes remarkably changed after the TRAS patients had undergone renal artery dilatation or stent implantation.PSV of the main renal artery and the POST-PSV ratio decreased significantly,and the PSV of interlobar arteries increased.Conclusions CDFI is a reliable first choice for screening transplant renal artery stenosis.The POST-PSV ratio has relatively higher sensitivity and specificity in the diagnosis of TRAS.
