Abstract
Abstract Aims Upper tract urothelial cancer’s (UTUC) are rare of which 17% have concurrent BT’s. Whilst CTU is the gold standard imaging for UTUC, its routine use is questionable due to low diagnostic yield.1 There is no consensus in our department regarding the use of CTU in screening haematuria patients, regardless of whether a BT is identified. We therefore sought to investigate the diagnostic yield of CTU. Method Retrospective case-note review of haematuria patients (May-October 2018), screening tests utilised and their diagnostic yield. Results 764 patients (mean age=68) presented with VH (n = 448) or NVH (n = 316). All underwent flexible cystoscopy (FC) and upper tract imaging, (346 = USS; 126=CTU; 257= USS and CTU). BT and UTUC were diagnosed in 69 (9%) and 5 patients (0.7%), respectively. Of the 5 patients with UTUC (VH = 4, NVH=1) 2 had synchronous bladder tumours, both were low grade. All 5 underwent CTU but only 3 had a prior USS, of which USS detected UTUC in 2 of these 3. CTU was performed in 384 patients (VH n = 323, NVH n = 61) yielding only one UTUC diagnosis when other investigations were negative. This patient presented with VH. CTU provided no additional cancer detection in all patients with BT. Conclusions Due to the small sample of synchronous tumours, location or grade of BT is not a predictor of UTUC2. In all patients screened with FC and USS, CTU only detected one additional UTUC. On the basis of these results, CTU screening is not indicated for patients presenting with NVH.
