OBJECTIVES: We reviewed the data of patients with upper urinary tract (UUT) tumors to evaluate the effectiveness of diagnostic procedures. METHODS: This retrospective study evaluated tumor characteristics, imaging procedures, epidemiological and follow-up data of 113 patients. We analyzed the importance of non-invasive and endoscopic diagnosis in addition to imaging as well as the influence of stage and grade on recurrence rate. RESULTS: Most tumors were urothelial carcinomas (92.9%). The cardinal symptoms were hematuria (40.7%), flank pain (2.7%), and urinary obstruction (14.2%). Forty-seven patients received intravenous urograms (IVUs), 57 retrograde ureteropyelography (RUP), 89 CTs, 6 an MRI. The correct positive tumor identification was reached by IVU in 27/47 patients, by RUP in 50/57, by CT in 74/89, and by MRI in 3/6 patients representing sensitivities of 57.4% (IVU), 87.7% (RUP), 83.1% (CT), and 50% (MRI). Sixty-four patients had urine cytology, which was correctly positive in 60.9% and 56 had a diagnostic ureterorenoscopy, which was correctly positive in 83.9%. During follow-up more than 20% of patients developed a recurrence. CONCLUSION: In patients with hematuria and flank pain, UUT must be considered a differential diagnosis. UUT to the extent of 76.6% showed more invasive growth (>Ta). Thus, rapid and efficient diagnosis based primarily on imaging is required. Contrast CT scan seems to be the imaging modality with the best performance. However, often only a combination of diagnostic procedures gives a certain diagnosis. Due to the high recurrence rate, close follow-up is needed.
