title: High-grade Carcinoma of the Proximal Ureter With Negative Nephroureteroscopy Detected by a Positive FISH Test: A Rare Case Report.
abstract: Upper tract urothelial carcinomas in the proximal ureter are an uncommon disease. We present a case in which it was firstly detected by fluorescence in situ hybridization and not by endoscopy and radiologic imaging. Consequently, a radical nephroureterectomy with excision of the bladder cuff was performed as the gold standard treatment.
