Factors of Acute Kidney Injury Donors Affecting Outcomes of Kidney Transplantation From Deceased Donors.

BACKGROUND: This study aimed to investigate the outcomes of kidney transplantation (KT) from deceased acute kidney injury (AKI) donors and analyzed the factors affecting these outcomes. METHODS: All patients who underwent KT from deceased donors at our institution from 1998 to 2016 were retrospectively reviewed. Recipients were divided into the AKI and non-AKI donor groups. We analyzed delayed graft function (DGF), serum creatinine levels at 1 month and 1 year after KT, cold ischemia time, donors' initial and terminal serum creatinine levels, Kidney Donor Profile Index, and patient and graft survival in each group. RESULTS: Of 181 recipients, 30 received kidneys from 21 AKI donors, whereas the remaining 151 received kidneys from donors without AKI. DGF more frequently developed in the AKI donor group than in the non-AKI donor group (40% vs 7.28%; P = .001). Allograft functions at 1 month and 1 year after KT did not differ between the AKI and non-AKI donor groups (1 month: P = .469; 1 year: P = .691). Factors affecting DGF were recipient weight and donor AKI. Recipient factors affecting graft function at 1 year were recipient height, length of hospital stay, serum creatinine levels at 1 month and 6 months, and biopsy-proven acute rejection. Older donor age was the only donor factor that affected graft function at 1 year. CONCLUSION: KT from deceased AKI donors showed a higher DGF rate but favorable patient and graft survival and graft functions. Donor AKI and recipient weight affected DGF, and only older donor age affected graft function at 1 year.

Extrinsic compression of left iliac vein does not predict the development of post thrombotic syndrome in left side deep venous thrombosis.

PURPOSE: Left side deep venous thrombosis (DVT) is associated with May-Thurner's anatomical variation and is often instigated by invasive treatment. The aim of this study is to analyze the influence of left iliac vein narrowness on incidence of post thrombotic syndrome (PTS) that developed after left side DVT. METHODS: Forty-one left side DVT cases that were followed up for more than 1 year were enrolled. The iliac vein narrowness was measured by the shortest distance from the right iliac artery to the 5th lumbar vertebra overlying left iliac vein in computed tomography (CT) scan. The incidence of PTS was measured by phone-call history taking for specific symptoms of PTS. The means of the shortest distance were compared by independent t-test. RESULTS: The number of PTS cases was eleven (26.8%). The level of thrombus, demographic data and other risk factors were similar in both PTS and non-PTS groups except the mean risk factor score. The mean of the shortest distance of PTS group and non-PTS group were 5.56 mm and 5.89 mm, respectively. CONCLUSION: The degree of left iliac vein narrowness measured by the shortest distance from the right iliac artery and the 5th lumbar vertebral body was not a predictive factor for PTS.
