Dr. Lee is a board-certified nephrologist and Postdoctoral Research Fellow in the Nephrology Division of the Stanford Department of Medicine.

He delivers expert, compassionate kidney care personalized to each patient he serves. Dr. Lee is committed to improving both the health and quality of life of his patients.

He has conducted research and presented peer-reviewed abstracts on topics such as the kidney secretions of hemodialysis patients and the risk of postoperative kidney injury in patients with chronic kidney disease. He also has presented on the association of therapeutic hypothermia after cardiac arrest with serum potassium levels and mortality.

His work scholarship has appeared in the Journal of the American Society of Nephrology, Kidney Week, Critical Care Medicine, Chest Journal, and Journal of Hospital Medicine.

Dr. Lee has received honors and awards including the prestigious Ben J. Lipps Research Fellowship from the American Society of Nephrology. The program funds original research projects by nephrology fellows.

  • Impaired Tubular Secretion of Organic Solutes in Advanced CKD. Journal of the American Society of Nephrology : JASN Mair, R., Lee, S., Plummer, N., Sirich, T., Meyer, T. 2021


    Background The clearance of solutes removed by tubular secretion may be altered out of proportion to the glomerular filtration rate (GFR) in chronic kidney disease (CKD). Recent studies have described considerable variability in the secretory clearance of waste solutes relative to the GFR in patients with CKD. Methods To test the hypothesis that secretory clearance relative to GFR is reduced in patients approaching dialysis, we used metabolomic analysis to identify solutes in simultaneous urine and plasma samples from 16 CKD patients with an estimated GFR of 7±2 ml/min per 1.73m2 and 16 control participants. Fractional clearances were calculated as the ratios of urine to plasma levels of each solute relative to those of creatinine and urea in CKD patients and to those of creatinine in controls. Results Metabolomic analysis identified 39 secreted solutes with fractional clearance >3.0 in control participants. Fractional clearance values in CKD patients were reduced on average to 65%±27% of those in controls. These values were significantly lower for 18 of 39 individual solutes and significantly higher for only one. Assays of the secreted anions phenylacetyl glutamine, p-cresol sulfate, indoxyl sulfate, and hippurate confirmed variable impairment of secretory clearances in advanced CKD. Fractional clearances were markedly reduced for phenylacetylglutamine (4.2±0.6 for controls versus 2.3±0.6 for CKD patients, P<0.001), p-cresol sulfate (8.6±2.6 for controls versus 4.1±1.5 for CKD patients, P<0.001), and indoxyl sulfate (23.0±7.3 versus 7.5±2.8, P<0.001), but not for hippurate (10.2±3.8 versus 8.4±2.6, P=0.13). Conclusions Secretory clearances for many solutes are reduced more relative to the reduction in GFR in advanced CKD. Impaired secretion of these solutes might contribute to uremic symptoms as patients approach dialysis.
