Segmental ureterectomy is not inferior to radical nephroureterectomy for either middle or distal ureter urothelial cell carcinomas within 3.5 cm

Objective To evaluate oncologic outcomes of segmental ureterectomy (SU) compared with radical nephroureterectomy (RNU) for urothelial carcinoma of ureter. To evaluate whether tumor position is a factor to influence outcomes of different surgical procedures.
