Detection of renal and renal pelvic tumours with urography and ultrasonography.
Urography and ultrasonography of the urinary tract were compared prospectively and blindly in 1306 patients. The patients were a non-selected group referred for urography over 1 year. Renal cell carcinomas were detected in seven patients and carcinomas of the renal pelvis in four patients. Urography detected carcinomas in 10 patients (sensitivity 91%) and falsely suggested malignancy in 52 (specificity 96%). Ultrasonography detected carcinomas in 10 patients (sensitivity 91%) and falsely suggested malignancy in 13 (specificity 99%). No difference between the two methods in detecting renal and renal pelvic tumours was observed in the studied population.
