they found in the ultrasound of my husband a 2cm cyst in his left lower pole kidney, what is the best way we will do because his doctor told him to take injection for 12 days and antibiotic to observe if the cyst will get small otherwise they will do surgery,
Simple cyst of the kidneys do not require any surgery unless there is repeated bleeding into the cyst in which case there may be debris with in the cyst on ultrasound. It is best left alone.
