Your symptoms are characteristic for partial renal or ureter
obstruction (described as hydronephrosis
). This state may be caused by kidney
stones (what is quite often), kidney/ ureter tumor, ureter narrowing, ureter compressions from outside (something inside abdomen cavity). Your ultrasound
shows a lobulated complex what should not be neglected (hypoecholic SOL - space occupied lesion is just a cyst, what is very often and not significant in that case). FNAC means fine-needle aspiration
cytology. It is a very good idea to rule a cancer out. This procedure looks like a regular injection where a sample of cells is being aspirated and can be exterminated under a microscope.
It is very important for you to find what is wrong with your kidney, as hydronephrosis is a pathological process which destroys your kidney.
Hope this will help
