Upper tract urothelial carcinoma (UTUC) diagnosis include urography using computed tomography urography (CTU) or urography using MRI (MRU). The sensitivity of CTU decreases substan¬tially with decreasing lesion size. Other drawbacks of CTU include the radiation exposure and potential adverse effects in patients with allergic reactions or pre-existing renal impairment. In terms of urine cytology, the major drawbacks of urine cytology are low sensitivity and highly dependent of the experience and skills of the cytopathologist. We here intended to investigate whether UroCAD can be added in the diagnostic work-up of UTUC patient, and improve the accuracy of predicting UTUC before surgery.
