Sir after ultrasound scan of abdomen of my grandfather.reports noted that exophytic SOL in mid pole of  left kidney which  is isoechoic with hyoerechoic foci within.that  is of size 20x18mm . Doctors are giving tablets. What is the best treatment please suggest.
After hearing of the lesion, first thing which concerns me is tumor (malignant/otherwise). I think, if after a course of antibiotics (which is unlikely to benefit, unless there is fever) if the SOL persists, it is better to get it removed.
