Comparison of biopsy devices inupper tract urothelial carcinoma

Introduction A correct characterization of upper tract urothelial carcinoma (UTUC) lesions is fundamental to appropriately select patients suitable for endoscopic management. We analyzed the diagnostic yield of three different biopsy tools for the histology evaluation of the UTUC. Furthermore, the concordance between biopsy grading and final UTUC pathology results at specimen (i.e., after ureterectomy or radical nephroureterectomy—RNU) was evaluated.
