Hello Dr. My wife, aged 54 years, is a Type 2 Diabetic patient for > 8 years. An expert opinion from Urologist is requested for the condition mentioned below: We had taken (at Anderson Diagnostics & Labs, Nungambakkam Centre) whole abdomen CT on 23.7.2017. And FDG P.E.T. WHOLE BODY & Mr. SCREENING on 3.8.17. Both reported that" ill-defined heterogeneously enhancing hypodense lesion (size 34*25*20 mm) was noticed in the anterior parapelvic region of her Left Kidney near the lower pole" In these two reports, there is no word about malignancy, tumor or cancerous growth. Then, > 3 nephrologist had stated that, it is up to the Urologist to decide about further course of action. As per Urologist's opinion, (without removing her left kidney), the lesion must be surgically removed. My questions are: (1) Is it necessary to do nephrectomy at the earliest or can we wait and do a short term review after about one month? (2) What will be the side effects of the surgical procedure? (3) For how many days the patient may be required to be hospitalized and what will be the approx. Total expenditure for this in any standard hospital in Chennai? (4) What could happen in future, to the left kidney of my wife, if she simply, as usual remains at house, without undergoing this surgery? P.S. The size of both her kidneys had shrunk by one sq. Cm. During the past 2 years. The old reports, dated 30.11.2016. And 30.05.2015. Did not indicate any mass or lesion. After 2014, she had lost > 20 kg of her body weight. There is no physical discomfort to her till date and she is able to carry on her daily routine. Thank you.
