What are the differences in outcomes between radical nephroureterectomy and conservative, endoscopic management of urothelial tumors of the renal pelvis and ureters?

Answer

No randomized studies have been performed, and no studies have had good long-term follow-up. Selection bias confounds nonstandardized studies. Tumors treated with endoscopic management are generally smaller, of low grade, and of low stage.

The 5-year disease-specific survival rate in patients with low-grade disease is statistically similar for conservative treatment and immediate nephroureterectomy, at 86.2-100% vs 87.4-89%, respectively. [56, 57]

Silberstein et al, in a 2012 study, showed that although oncologic outcomes were similar, a significantly larger decrease in glomerular filtration rate was noted in patients undergoing nephroureterectomy compared with endoscopic treatment. [58]
