Kidney masses
An_251817 posted:
My relative was recently diagnosed with kidney failure, and the nephrologist says she has a few masses in one kidney. He wants her to see a urologist. I am confused. I thought urologists dealt with the bladder and other urinary structures/functions and nephrologists dealt with the kidneys. The nephrologist also stated they would probably need to remove the affected kidney. Is there no other way to determine if these masses are malignant?

Nephrologists deal with all the complex biochemical process of the kidneys, everything from signalling bone marrow how many red blood cells to produce to blood pressure. Urologist deal with the physical structures of the whole urinary system, but not the body chemistry is controls.

The reason that percutaneous needle biopsy is often not used for kidneys is this: because of the texture of renal tissue and the location of the organs, there is a risk that---should the mass be malignant---there is a chance of spreading a few random cells around in the abdomen, and that poses a chance of creating metastatic problems where there was none before.

It's a case by case judgement for the urologist and the oncologist.
