- Objective Computed tomography urography (CTU) can be used to direct further investigation of patients if the bladder tumour detection rate is high. The aim of this study was to compare a CTU protocol including an enhancement-triggered scan and flexible cystoscopy for detecting bladder tumours.Materials and methodsPatients with gross haematuria undergoing CTU during 2005–2008 were included. For patients younger than 50 years the CTU protocol included unenhanced, enhancement-triggered corticomedullary, and excretory phases. Patients older than 50 years followed the same protocol plus a nephrographic phase. The entire urinary tract was examined in all phases.ResultsOf 435 patients, 55 patients were diagnosed with bladder tumour. CTU detected bladder tumour in 48 patients (87%). Five CTU examination reports were false positive. With CTU, sensitivity for finding bladder tumour was 0.87, specificity 0.99, positive predictive value (PPV) 0.91 and negative predictive value (NPV) 0.98. Cystoscopy detected bladder tumour in 48 patients (87%) and had one false-positive finding, resulting in sensitivity of 0.87, specificity 1.0, PPV 0.98 and NPV 0.98.ConclusionsThe detection rate of bladder tumours for the CTU protocol including an enhancement-triggered scan was high and comparable to flexible cystoscopy. Hence, this protocol could be used to assess the bladder as the primary investigation and direct further investigation of the patient.
