The reduction of renal mass after radical nephrectomy (RN) for renal neoplasm, could be associated with compensatory hypertrophy of the contralateral kidney. The capacity of compensation will determine the renal function (RF) evolution. Measuring of total renal volume (TRV) of the remaining kidney pre and post RN can help assess the RF evolution. To determine the correlation between TRV pre and post nephrectomy (a year of follow-up) with RF. A retrospective cohort study was carried out in 47 patients who had undergone RN from 2014 to 2018, due to renal cell carcinoma (confirmed by histopathology). The TRV was calculated, pre and post (a year of follow-up) RN, using ellipsoid formula equation, which were compared with clinical and analytical data. The results were analyzed by multivariate linear logistic models. The median age at the time of RN was 70 years old (range, 40-88 years). Most of them were men, 66%. The estimated glomerular filtration rate (eGFR) pre and post nephrectomy was 78 (40-100) and rrelated negatively (β=-1.18; P=.047) CONCLUSIONS The measurement of pre and post nephrectomy TRV can help to predict renal function evolution at a year of follow-up.Pasteurized donor human milk is in wide use for preterm infants in neonatal intensive care units when maternal milk is unavailable. Pasteurization of donor milk is required to prevent bacterial contamination, and multiple methods are used in the non-profit and commercial milk banking industries. Pasteurization results in changes in the nutrient and bioactive components in donor milk compared to unpasteurized human milk, and these changes vary by the type of pasteurization process. Other milk bank practices including freezing of milk, pooling of milk from multiple donors and use of pre-processing macronutrient analysis
