Abstract

Fifty years ago, Robson introduced radical nephrectomy (RN) setting the gold standard for treating kidney tumors. Experience has shown that partial nephrectomy (PN) can be equally effective with the advantages of preserving kidney function and avoiding unnecessary nephrectomies for benign tumors. The purpose of this report is to demonstrate the evolution of clinical presentation and choice of treatment for patients with kidney tumors at our department, emphasizing changes in the PN utilization trends. Clinical data were abstracted for the years 2002, 2007 and 2012. We assessed annual trends for changes in the choice of operative treatment related to tumor size, pathologic stage and diagnosis. During the study, there was an increase in the share of T1 tumors, from 46.6% in 2002 to 69.8% in 2012. The rate of PN increased more than ten-fold, from 2.7% in 2002 to 31.7% in 2012. The annual rates of PN for T1 tumors increased even more, from 6.6% in 2002 to 46.7% in 2012. Opposite to RN group, there was an increase in the mean tumor size in PN group (from 1.8 cm in 2002 to 3.9 cm in 2012). The rate of RN for benign tumors was reduced impressively from 85.7% in 2002 to 23.1% in 2012. Our data argue strongly that PN should be expanded and not restricted. Robson's principles have been partially deserted over the last decade; however, proving that PN is superior to RN still remains to be elucidated.
