 Many patients are seen in The Urology Clinic for the evaluation of a mass in the kidney. This mass may have been discovered at the time of an x-ray or ultrasound being performed for another reason (an incidental finding) or as part of an investigation into a patient’s symptoms or abnormal lab results.
Causes of Kidney (Renal) Mass
There are many causes for a mass in the kidney and may include the following:
- Renal cyst (benign)
- Anatomic variations
- Infection of kidney
- Hydronephrosis or partial blockage of kidney
- Kidney tumors (benign and malignant)
Evaluation
The evaluation begins with a detailed history and physical examination and may include the following:
- Urine cytology
- Cystoscopy
- CT scan
- Renal ultrasound
- MRI scan
- Basic Metabolic Panel (BMP)
- Complete Blood Count (CBC)
Treatment
The course of treatment of a kidney mass is individualized to each patient. Many masses are benign (non-cancerous) and may need no further evaluation. Some masses require followup CT scan, ultrasound, or MRI imaging. Others that appear to be cancerous may be treated in a variety of ways depending on the size, location, and other medical problems and may include the following:
- Radical nephrectomy
- Partial nephrectomy
- Laparoscopic radical nephrectomy
- Laparoscopic cryotherapy
