ICD-9 codes from the National Inpatient Sample, from 2001 to 2013, were used to collect data for a retrospective cross sectional analysis. A total of 106,721 radical nephrectomies were performed during the study period. Of this total, 87,951 were open, 15,105 were laparoscopic, and 3,665 were robotic. Additionally, a total of 29,370 partial nephrectomies were performed, of which 20,532 were open, 2,056 were laparoscopic, and 6,782 were robotic.

Researchers concludes that while minimally invasive approaches have been increasing, open renal surgery still represents a larger proportion of the cases being performed at teaching institutions. One member of the audience made note on how the study has a tremendous amount of implications on training and its somewhat comforting to see that open nephrectomies still exist. However, it was found surprising that open radical nephrectomies are increasing and this raises the question of what type of complex tumors are being dealt with that require for physicians from teaching hospitals to be referred. One future direction can be to assess the tumor complexity of this dataset to further gain insight on the trends of open and minimally invasive approaches for radical and partial nephrectomies, in training and nonteaching institutions.
