Kidney Neoplasms
Conditions
Brief summary
The purpose of this study is to determine if biopsy for non-neoplastic renal disease for patients with a small renal mass results in greater postoperative renal function than the current standard of care (no additional biopsy).
Interventions
• Patients in the experimental group receive the additional biopsy for non-neoplastic disease during the same procedure before the biopsy of the renal mass (with potential for direct benefit to the patient by revealing non-neoplastic renal disease).
