Preoperative Prediction and Postoperative Surgeon Assessment of Volume Preservation Associated With Partial Nephrectomy: Comparison With Measured Volume Preservation

摘要

OBJECTIVE To evaluate whether surgeons can predict the percent parenchymal mass that will be preserved by partial nephrectomy (PN) based on preoperative imaging, which could have potential utility for preoperative surgical planning and patient counseling. The proportion of preserved viable parenchyma following PN is the primary determinant of functional recovery. However, direct measurement of parenchymal volume preservation (VP) can be complex and time consuming.
