Adjuvant Intraluminal Therapies in Upper Urinary Tract Urothelial Tumors

Abstract

The gold standard treatment option for upper urinary tract urethelial tumors is radical nephroureterectomy and bladder cuff resection. On the other hand, with the development of surgical techniques, improvement in endoscopic instruments and better risk stratification in recent years, minimally invasive endoscopic procedures and renal-sparing surgical approaches such as segmental/total ureterectomy have begun to be applied. Metachronous tumor recurrences can be seen despite the use of renal-sparing approaches in selected patients. Adjuvant intraluminal treatments are applied in upper urinary tract tumors to reduce tumor recurrences. In this review, we discussed the role of adjuvant intraluminal therapies.
