摘要

These authors postoperatively quantified renal functional loss in patients with a solitary kidney undergoing PN. They evaluated the correlation of tumor complexity measured by the nephrometry score with eGFR changes. The primary conclusion was that the nephrometry scoring system did not predict renal functional loss. We caution that eGFR estimations were not developed or validated to measure short-term changes in renal function but rather to classify CKD stages. Functional loss can be determined more accurately by othalamate glomerular filtration rate measurement.
