External validation of yonsei nomogram predicting chronic kidney disease development after partial nephrectomy: An international, multicenter study

Abstract

AbbreviationsAKI = acute kidney injury BMI = body mass index CKD = chronic kidney disease DM = diabetes mellitus PN = partial nephrectomy PPV = positive predictive value RN = radical nephrectomy RPN = robotic partial nephrectomy WIT = warm ischemia time

Editorial Comment on External validation of Yonsei nomogram predicting chronic kidney disease development after partial nephrectomy: An international, multicenter study

“…In this issue of the International Journal of Urology, the external validation of the Yonsei nomogram is provided, based on a multicentric dataset including 3500 patients of various ethnicities with a minimum follow‐up of 12 months (median = 47 months) 4 . CKD‐free progression probability at 1, 3, 5, and 10 years was calculated for all patients.…”

Editorial Comment to External validation of Yonsei nomogram predicting chronic kidney disease development after partial nephrectomy: An international, multicenter study

“…Abdel Raheem et al. conducted an external validation study of the Yonsei nomogram with 3526 patients in mostly Western countries 2 . The area under the curve value was 0.69, 0.72, 0.77, and 0.78 for the prediction of new‐onset CKD at 1, 3, 5, and 10 years, respectively.…”

“…The original MDRD equation improved the accuracy of GFR estimation in the Japanese population by a coefficient of 0.881 4 . Patients who developed new‐onset CKD were 13.1% of the original Korean cohort, whereas they were 19.4% of the external validation cohort 2 . In addition, the overestimation of eGFR in Asian patients may have caused the miss determination of patients without CKD.…”
