Urothelium is the specialized epithelium that covers the urinary collecting system from the tips of the renal papillae to the prostatic urethra. Tumors of the urothelium can be benign but the vast majority are malignant carcinomas. Carcinomas of the urothelium are common and the upper urinary tract is the affected site in roughly 5% of cases. Similarly, 5–10% of tumors that involve the kidney a...

متن کاملEndoscopic Management of Upper Urinary Tract Urothelial Carcinoma
Upper urinary tract urothelial carcinoma (UTUC) is relatively uncommon. Radical nephroureterectomy with an ipsilateral bladder cuff excision has been the gold standard treatment for UTUC. However, recent advances in technology have made possible the increased use of endoscopic management for the treatment of UTUC. The definitive goal of endoscopic management of UTUC is cancer control while main...
متن کاملUpper urinary tract urothelial carcinoma with intratubular spread.
Upper urinary tract urothelial cell carcinomas (UUT-UCs) are uncommon and are defined as urothelial carcinoma involving the urinary tract from the renal calyces, renal pelvis to the distal ureter.
