Incidental mass
A finding on ultrasound, CT, or MRI performed for another reason.

Kidney oncology
Kidney cancer and kidney preservation.
Evaluation of kidney masses and surveillance, partial surgery, radical surgery, or ablation based on size, location, and risk.
A kidney mass needs characterization before a decision. Size, anatomy, function of both kidneys, other health conditions, and the likelihood of malignant behavior help determine whether surveillance, biopsy, local treatment, or surgery is appropriate.

Reasons for evaluation
Confirmed diagnosis
A need to review stage, anatomy, and kidney-preserving options.
Surgical second opinion
Compare partial nephrectomy, radical nephrectomy, ablation, or surveillance.
Structured evaluation
Kidney planning
Cancer control is balanced with preserving kidney function when safe and technically feasible.
01
Characterize the lesion
Contrast CT or MRI may define size, location, and vessel relationships.
02
Review kidney function
Laboratory results, the opposite kidney, and health conditions influence strategy.
03
Define extent
The evaluation determines whether disease appears localized or needs further study.
04
Choose an approach
Surveillance, biopsy, ablation, or surgery are compared around risk and feasibility.
Informed decisions
Options based on anatomy and stage
Not every kidney mass requires removal of the whole kidney.
Active surveillance
Monitoring selected small masses when the clinical balance supports it.
Partial nephrectomy
Removing the tumor while preserving the remaining kidney when appropriate.
Radical nephrectomy
Removing the kidney when size, location, or extent makes it necessary.
Ablation or other therapies
Local or systemic options considered in selected settings.

Safety notice
Visible blood in urine, new severe pain, fever, marked weakness, or rapid deterioration require timely assessment. Decisions should use complete imaging and clinical context.
Frequently asked questions
Answers to prepare your next step.
No. Some are benign or indeterminate. Imaging, growth, clinical context, and selected biopsy can help.
