Renal Function and Oncologic Outcomes of Parenchymal Sparing Ureteral Resection Versus Radical Nephroureterectomy for Upper Tract Urothelial Carcinoma

Abstract

Parenchymal sparing ureteral resection is associated with superior postoperative renal function. However, the impact on cancer control cannot be determined conclusively due to the small sample size and putative selection bias.
