چکیده
BACKGROUND/AIMS We have reported that the eGFR overestimates renal function when glycemic control is poor. It has been reported that eGFR calculated by serum creatinine underestimates GFR in living kidney donors. We compared the utility of the eGFR in diabetic patients, non-diabetic patients and living kidney donors. Forty diabetic patients, 40 non-diabetic patients, and 40 living kidney donors were enrolled. METHODS GFR was measured by inulin clearance (C(in)). eGFR was calculated based on serum creatinine (eGFR(cr)) or serum cystatin C (eGFR(cys)). We compared the agreements between each of the eGFR and C(in) in each group. RESULTS There were significant and positive correlations between each eGFR and C(in) in diabetic patients and non-diabetic patients. However, the intraclass correlation coefficients (ICC) between each eGFR and C(in) in diabetic patients (ICC: eGFR(cr) 0.699, eGFR(cys) 0.604) were weaker than those in non-diabetic patients (ICC: eGFR(cr) 0.865, eGFR(cys) 0.803). The correlation coefficients between each eGFR and C(in) (eGFR(cr); r = 0.422, p = 0.0067 and eGFR(cys); r = 0.358, p = 0.0522) in living kidney donors were significantly weaker than those in non-diabetic patients. The ICCs between each eGFR and C(in) (ICC: eGFR(cr) 0.340, eGFR(cys) 0.345) in living kidney donors were significantly weaker than those in non-diabetic patients. CONCLUSIONS Based on C(in), eGFR was accurate in non-diabetic patients. However, eGFR was inaccurate in living kidney donors and relatively inaccurate in diabetic patients.

Introduction: The constantly increasing incidence of type 2 diabetes, probably due to obesity and sedentary life, has led to the increased incidence of macro- and microvascular diabetic complications such as nephropathy. Despite the prompt efforts to develop effective treatments for diabetes and slow the progression of its complications, it is still reported as the most common cause of chronic ...

BACKGROUND Patients with medullary sponge kidney (MSK) commonly encounter recurrent nephrolithiasis. The existing knowledge on safety of donors with MSK has not been studied. METHODS We conducted a retrospective cohort study at a tertiary referral hospital to assess the outcomes of living kidney donors with MSK. All adults with MSK (N = 26) who underwent nephrectomy as living kidney donors be...

BACKGROUND Neutrophil gelatinase-associated lipocalin (NGAL) is a promising biomarker of acute kidney injury. There is a growing body of evidence suggesting that NGAL is also a marker of kidney disease and severity in chronic kidney disease (CKD). We studied the utility of urinary NGAL in more accurately predicting renal function in patients with diabetic CKD. METHODS We studied possible rela...
