Over a 5-year period, 1007 patients with haematuria were investigated, using a protocol based on ultrasonography as the upper tract imaging modality of choice. Intravenous urography (IVU) was only used in selected individuals, including those patients with bladder cancer suspected on cystoscopy, suspicious or malignant cytology, previous investigation for haematuria, on-going haematuria at the time of their clinic visit, a history of flank pain or hydronephrosis on ultrasonography. Of this series, 840 (83%) had visible haematuria, 158 (15%) had microscopic or chemical haematuria and 9 (0.9%) had unspecified haematuria. A total of 133 bladder transitional cell tumours, 21 renal cell cancers and 2 upper tract transitional cell cancers (TCC) were diagnosed. The sensitivity of ultrasound with respect to bladder cancer was 63% and the specificity 99%. The odds ratio of diagnosing cancer in patients with visible haematuria compared to microscopic or unspecified haematuria was 3.3. No upper tract tumours were missed using this investigational protocol. An ultrasonography-based protocol could miss fewer upper tract TCCs than a standard IVU-based service would miss renal cell cancer. Provided there is no history of flank pain, no malignant cytology, no hydronephrosis and no previously investigated haematuria, IVU could be safely omitted.
