The sensitivity of ultrasound for detecting upper tract TCCs is low (13%) which is potentially related to user technique and the limited assessment of the ureter on ultrasound.
CT has excellent sensitivity for detecting upper tract TCCs (100%) but our pick up rate was 84%.
The low sensitivity of US and diagnostic misses by radiologists has contributed to delays in diagnosing upper tract TCCs.
Common pitfalls in identifying these tumours included not recognising hyperattenuating lesions within the renal collecting system and not identifying ureteric wall thickening.
Having presented these findings at our local radiology and urology departmental meetings we are aiming to change to CT as the initial imaging test for macroscopic haematuria.
