Dear Doctor, My husband was diagnosed with mild left pelvicalceal dilation with normal uretic jets. So far his other laboratory test for kidney, liver and artery doppler test were normal. But my problem is he has microscopic hematuria. Does it has something to do with the dilation of the left kidney?What causes the dilation? His GP did not give him medicine cause according to him sometimes it is normal to have hematuria and laboratory were normal. Please enlighten me about this. My husband is 43 years old, non smoker/ non drinker and don t feel any pain when urinating.Thank you,Len
