Infections

Different imaging modalities can rule out predisposing causes for urinary tract infections, but (except in rare conditions) the infection per se can not be visualised. Some predisposing factors are: congenital abnormalities of the collecting system like obstruction and duplications, stone disease with or without obstruction, contemporary tumours.

Especially in recurrent upper urinary tract infections it is important to do diagnostic imaging to rule out occult predisposing disease.
