Upper tract urothelial carcinoma (UTUC) accounts for roughly 5% of urothelial carcinomas. Historically, the gold standard for high-risk or bulky low-risk UTUC was an open radical nephroureterectomy with formal bladder cuff excision (BCE). The development of novel endoscopic, laparoscopic, and robotic techniques has transformed this operation, yet no level I evidence exists at present that demonstrates the superiority of one strategy over another. While new approaches to nephroureterectomy in the last decade have shifted the management paradigm to decrease the morbidity of surgery, controversy continues to surround the approach to the distal ureter and bladder cuff. Debate continues within the urologic community over which surgical approach is best when managing UTUC and how various approaches impact clinical outcomes such as intravesical recurrence, recurrence-free survival (RFS) and disease-specific mortality (DSM). When focusing on the existing treatment algorithm, key metrics of quality include (I) removal of the entire specimen en bloc, (II) minimizing the risk of tumor and urine spillage, (III) R0 resection, and (IV) water-tight closure allowing for early use of prophylactic intravesical chemotherapy. In the absence of robust evidence demonstrating a single superior approach, the urologic surgeon should base decisions on technical comfort and each patient's particular clinical circumstance.
