— Renal pelvis tumours represent 5–10% of renal neoplasms. 75–80% are malignant and 90% of these are transitional cell tumours. Haematuria is the most common sign It is important that a correct management of diagnostic imaging should be followed. For this reason a retrospective study on 51 patients with carcinoma of the pelvicalices has been carried out. By comparing the association of all three examinations (ultrasonography, urine cytology and urography) a more specific diagnosis can be obtained. A single exam has already proved to be insufficient, and risks being false negative. Retrograde pyelography and CT also proved to be very useful in completing the diagnosis.
