Is a kidney biopsy necessary to find out why there is protein leakage?

Doctor's Answer

Hello,

Without knowing all the pertinent details, it sounds like your relative has been advised to go for a kidney biopsy procedure to find out the cause for the protein leakage, which seems like it has faced a sudden jump in a relatively short period of time (ie 2 months).

A kidney biopsy is NOT a surgery per se; rather, it is a minor procedure whereby a doctor inserts a thin biopsy needle through the patient’s side to remove a very small amount of kidney tissue. This is then sent to the lab for examination.

Again, I do not know the exact circumstances in which the doctor has advised for this procedure, but my best guess is that there was no obvious cause for this sudden jump in protein leakage.

A kidney biopsy will be able to reveal much more information than blood and urine tests, and sometimes a correct diagnosis can only be made from the results of the biopsy.

It may be important to find out the cause to prevent the condition from worsening.

Can diet contribute to a patient’s major change in protein leakage?

A diet rich in protein can result in more issues with protein leakage for patients with kidney problems, so they are often placed on special diets. She should speak to the dietician about what diet to be on.

However, it’s unlikely in this case that her diet alone caused the jump in protein leakage.

Will she have to go for kidney dialysis soon? Anything she can do on her side to prolong her health to prevent condition from worsening?

I’m unable to comment on the need for dialysis, as there are too many factors that control when a patient needs to be placed on dialysis. You or she needs to talk to the kidney doctor about this, including how to prevent her condition from worsening. This will in turn depend on the cause for her kidney problems.
