In total, 90% of uroepithelial tumours are TCCs and 90% are found in the bladder. The remainder are SCCs, associated with chronic infection and strictures. Most TCCs are exophytic/polypoid (papillary TCC). Non-papillary is flat, aggressive and stricturing. About 30% with upper tract tumours will develop disease in the bladder (i.e. it drops down). Metastasises to local nodes, liver, lung and bone.
US
• Obstructed kidney
• Polypoid lesion in the bladder with or without vascularity
CT
• Intraluminal filling defect/mass showing arterial enhancement or thickening/narrowing of the ureter/collecting system
• Infiltration of the renal parenchyma or renal sinus
MRI
• T1 useful for assessing extension into perivesical fat
• Tumour brighter on T2 than adjacent bladder wall
