Hi and welcome to Chat Doctor. Thank you for your query. Nothing is wrong with you. This is common finding and as it says this is just mild dilatation. It means that there is some minor obstruction of your urogenital tract. This is most common in prostate or ureterocystic junction. You need to do prostate ultrasound first to evaluate this. ALso, there could be some stone which passed, and it could cause cancel dilatation. There is no treatment necessary at this point but taking enough liquids. You just need to do frequent check-ups.Wish you good health.
