Methods and materials
We conducted a retrospective review of patients diagnosed with upper tract TCCs over a 5 year period from 2013-2017.
we accessed the pathology database to identify all patients who underwent nephro-ureterectomy with a subsequent diagnosis of TCC during this time period.
Patients with metastatic disease or those who underwent ureteroscopic laser treatment for upper tract TCCs were not included in analysis.
All scans prior to the date of surgery that included the renal tract were reviewed.
Discrepant cases were highlighted and the sensitivity of both US and CT in detecting these tumours was determined.
The time to diagnosis was recorded as the number of days from the initial imaging test that showed the tumour to the earliest CT scan where the tumour was correctly identified.
