Kidney-Sparing Surgery Has Equivalent Oncological Outcomes to Radical Nephroureterectomy for Ureteral Urothelial Carcinoma

Kidney-sparing surgery (KSS) for upper tract urothelial cancer (UTUC) has gained increasing interest recently. However, there is limited contemporary data regarding the role of KSS in ureteral urothelial carcinoma. Therefore, we investigated the survival outcomes of ureteral urothelial carcinoma after KSS from a large, prospective international UTUC registry.
