Question: Cyst and tumor in Kidney


 Ankit - Thu Nov 19, 2009 2:36 am

Dear Doctor,

My mother is 45 years of age. A cyst measuring 12cm has been detected in the CT scan. In addition to that the doctors said that there is a tumor also and that the cyst has covered the whole kidney and kidney is not funtioning. The treatment they have suggested is Surgical and that they would removing one of the kidney. Is this the only solution and wouldnt the removing of one of the kidney create problem in future. Please suggest.

Thanking You

Ankit

User avatar Hi,
Currently the standard for further evaluation of renal cysts is abdominal CT with or without contrast. Bosniak has proposed a classification of renal cystic lesions based on abdominal CT findings.Based on this system, they are classified as
Bosniak I— IV. This roughly means...

Bosnaik 1- it's a benign cyst. 2- We're still pretty certain it's a cyst. 3- We don't know what it is. 4- It's probably a tumor.

Renal cell carcinomas may occassionally present as cystic masses. Perhaps that is what happened in your mother's case(Bosniak IV).

Usually following a nephrectomy, the remaining kidney(if normally functioning) is adequate enough. In renal cell carcinoma,if 'paraneoplastic syndromes' (esp, hypercalcemia,amyloidosis and hypertension) do not develop and the patient (if obese) reduces weight/stops smoking, the remaining kidney has a fair chance of lasting the lifetime of the patient.

Best wishes!
