What is Renal Oncocytoma?Renal oncocytoma is a rare benign (non-malignant) tumour of the kidney. They are benign tumours and usually do not spread to the other distant parts of the body. They account for approximately 5% of primary renal epithelial cell carcinoma. Renal cancer usually affects people between the ages of 60 and 70, with a peak incidence at the age of 50. It occurs in men 2 times more often than in women.
Disease Etiology (Causes)There is no well-known cause; however, they are associated with certain genetic diseases such as Birt-Hogg-Dub syndrome and tuberous sclerosis.
Signs and SymptomsIn most cases, there are no symptoms, and cancer or renal tumour is detected on the occasional radiologic examination. In advance cases, the patient may develop the following signs and symptoms. These are
- Pain in the loin
- Passage of blood or blood particles in the urine
- A palpable mass in the loin or abdomen
- Unexplained weight loss
- Night sweats
- High blood pressure
DiagnosisThe following diagnostic tests and procedures can be used to make a diagnosis. These are
- Imaging techniques like CT-abdomen and pelvis, USG abdomen and pelvis, MRI, CT-chest, and X-ray to assess the site, size, extent, and distant metastasis of the tumour.
- Renal arteriography ( Ultrasonography of the main artery of the kidney)
- Intravenous pyelogram
