Renal Hilar Lesions: Biological Implications for Complex Partial Nephrectomy.

ABSTRACT:

Objective

To perform a comprehensive histopathologic review of sporadic resected solitary cT1 renal masses comparing those with and without radiographic involvement of the hilum.

Materials and methods

A prospectively maintained database was queried for all cT1 renal masses undergoing resection classified per the R.E.N.A.L. nephrometry score. Hilar masses were defined as tumors that abut the main renal artery or vein on cross-sectional imaging. Demographic, treatment, renal mass, and histopathologic characteristics were compared between hilar and nonhilar renal masses. Multivariate regression model analyses were performed to assess factors associated with renal mass upstaging and disease recurrence.

Results

A total of 1324 stage 1 renal masses met criteria for analysis
