Robot-Assisted Ultrasound for Thermal Ablative Therapy in Treating Patients With Small Kidney Masses Undergoing Surgery

Inclusion Criteria: * Presence of an enhancing solid renal mass =\< 3.0 cm on radiological examination * Tumors with a depth of not greater than 3.0 cm from a laparoscopically accessible surface-meaning no part of the tumor should be deeper than 3.0 cm from the surface * Patients with solitary kidneys, bilateral renal tumors, compromised renal function (baseline creatinine \> 1.4) * Subjects must have given written informed consent * Previous chemotherapy, and/or biological therapy for cancer are permitted provided that the acoustic properties of the tumor were not affected, but the subject should have recovered from the effects of these or of any prior surgery * Subjects must be free of any clinically significant disease other than cancer that would interfere with the study evaluations * Absolute neutrophil count (ANC) \>= 1500 mm\^-3 * Platelet count \>= 100,000 mm\^-3 * Hemoglobin \>= 10 g/dl * Prothrombin time (PT) =\< 1.5 times upper limit of laboratory normal (ULN) * Activated partial thromboplastin time =\< 1.5 times ULN * Urea and serum creatinine \< 2.5 times ULN * Total bilirubin \< 1.5 times ULN * Aspartate aminotransferase (AST) =\< 3 times ULN * Alkaline phosphatase \< 2 times ULN, unless arising from bone Exclusion Criteria: * \< 90% solid component on screening cross-sectional imaging * Subjects deemed unsuitable candidates and not medically optimized for partial nephrectomy * Tumors greater than 3.0 cm at their widest point * Subjects with tumors lying \< 1…
