HEMATURIA - INTRAVENOUS UROGRAPHY, ULTRAS OUND OR BOTH

Purpose: To compare the diagnostic value of intravenous urography (IVU ), ultrasound (US) and their combination in detecting upper urinary tr act malignancies in patients with haematuria. Materials and Methods: I n a prospective study, 360 consecutive patients who consulted the urol ogist for haematuria without renal colic were scheduled for IVU and US on the same day. The two procedures were performed by two different r adiologists and reported independently. Histology or clinical follow-u p of one year served as the gold standard. Results: 63 patients droppe d out. Of the remaining 297 patients, 9 (3%) had a malignancy in the u pper urinary tract. Sensitivity and specificity with regard to the upp er urinary tract pathology were 67% and 91% for IVU and 56% and 94% fo r US, respectively. For both techniques combined this was 79% and 88%, respectively. Conclusion: An acceptable sensitivity for detecting upp er urinary tract malignancies is obtained only by combining IVU and US .
