    Video Interview on Optical coherence tomography as a tool for in vivo staging and grading of upper urinary tract urothelial cell carcinoma: Comparison with biopsies and histopathology of the resected specimen

    Introduction and Objectives: Optical Coherence Tomography (OCT) has potential to provide real-time information on UUT-UC grade and stage. In this study we compare a) biopsy and b) OCT with gold standard histopathology of the resected specimen (HRS) for grading and staging of low- and high-grade UUT-UC. Methods: 16 patients with UUT-UC underwent diagnostic URS, including OCT and biopsy of places with visible tumour. The 2.7 Fr OCT probe was delivered through the ureteroscopes work channel. Subsequently biopsy was performed. At a later stage, patients underwent nephroureterectomy. For staging by OCT, in-house developed protocols were used and visible lesions were ...
