Hi and welcome to HCM.
The most common liver disorder is fatty liver
which can be found in healthy people, but usually is resulting from elevated blood lipids
and elevated blood sugar. If ultrasounds didnt find anything and viral markers are negative then you have no reason to be concerned. YOu should treat it by changing dietary and lifestyle habits. Do exercise, avoid alcohol, smoking
, fats, fast food and carbonated drinks. Eat more fruit and vegetables, boiled meat and follow some of hepatoprotective diets. Findings usually improves on such measures. If not, then some medicines can be prescribed. dilatation of pelvicanaela sytem is mainly caused by stone and you need justr frequent check ups. Rarely it can be caused by tumors so if there is progression of dilatation you should do intravenous urography or ct scan
Wish you good health.Regards
