Sir/Madam,My wife get urinary infection 5 years ago. Ultrasound suggestd that her left kidney is shrinking and uretor not seen.  Though no solid ground was known but on the basis of 40 ESR, Doctor in PGI Chandigarh started Tuberculosis treatment for 18 month.  One year ago, treatment stoped. DTPA Scan showed Left kindney (shrink) is functioning only 10% while right kindly function is shown 90%.  In routine check up ultrasound not suggest that left kidnly is NOT SHRINK [mean it has grown to full] (bigger then right kidney)but function of kidney is less then 5%.  I am afraid, there may be some reason for its grow (may be cancer or any other thing).  I discussed the issue with Urologist who suggested kidney removal. Presently, Ceretine is 1.07 and urea is within limit.My question is :1. who is best nephrologist/ urologist to decide whether the kidney should be removed or not2. Is Urologist is competent to remove the kidney?2. Should I go to nephrology department for this operation. 3. Any other advise and 4. what is the cost involved in treatment.

### output:

Hello and welcome to Chat Doctor. As a Urologist, I can understand your anxiety very well.1. Both are equally competent to decide on kidney removal. Kidney showing less than 10% function are always removed, due to potential infection, affecting the normal kidney(right).2. Urologists are the most competent and experienced surgeons for this.3. Delay in treatment is risky. 4. Cost of treatment varies in hospitals, but free in medical college hospital. You may send doubts, as a direct question to me, for an expert opinion. Chat Doctor.
