[Diagnosis of diseases of the urinary tract]

Radiological exploration of the urinary tract has become highly sophisticated. The information provided by the new imaging techniques is extremely accurate and useful in the diagnosis and pretherapeutic assessment of most urinary tract diseases. Interventional radiology has given radiologists an important role in the treatment of some types of pathology. The authors describe the value of modern imaging and its different aspects in each of the principal branches of urinary tract pathology, viz.: tumours, obstructions, infections, vascular and prostatic diseases.
