OBJECTIVES: Upper tract urothelial carcinoma (UTUC) is relatively rare. While nephroureterectomy is considered the gold standard for treatment, endoscopic nephron- sparing techniques have emerged for select cases with equivalent cancer specific survival (CSS). We present the largest series with longest follow-up to date of retrograde ureteroscopy as the primary treatment of UTUC. METHODS: A retrospective review was performed of 258 patients diagnosed with UTUC who were initially evaluated and managed by a single surgeon. Patients were followed from 1994 to 2017. Clinical records were evaluated for patient and tumor characteristics, operative parameters and outcomes. Statistical analysis was performed to identify risk of recurrence, progression, cancer and overall survival. RESULTS: Following exclusion criteria, 168 patients were evaluated. Average tumor size on initial excision was 16.8mm. Mean age of the cohort was 70 years, with mean follow-up of 5.53 years. The 5-year overall survival was 80.9%, but CSS was 92.6%. Recurrence free survival was 30% with average tumor size on recurrence of 6.39mm. Progression free survival was 75% with a renal preservation rate of 71.4%. CONCLUSIONS: Ureteroscopic management of UTUC is a successful alternative to nephroureterectomy in select cases of UTUC. With strict surveillance protocols to manage frequent local recurrence rates, it is possible to achieve high renal preservation rates with acceptable CSS, even in the long-term.
