OBJECTIVE: To assess oncological outcome after first-line management of upper urinary tract urothelial cell carcinomas (UUT-UCCs) by exclusive flexible ureteroscopy.
MATERIALS AND METHODS: A retrospective review was performed for 35 patients treated between 2003 and 2007. All patients underwent retrograde flexible ureteroscopy for diagnosis, treatment (i.e., holmium:YAG vaporisation), and follow-up. The following data were reviewed: sex, age, ASA score, presence of a solitary kidney, unifocal or multifocal tumour, history of bladder cancer, tumour localisation, tumour size, stage and grade, outcome, recurrence, and progression.
RESULTS: The mean age was 67 + or - 13.1 years (range: 38-88). The tumour involved the renal pelvis and the caliceal system in 19 cases (54%), the ureter in 8 cases (23%), and both in 8 cases (23%). Twelve patients (34%) had a history of bladder carcinoma. Tumour stage was superficial in 63% (57% were pTa and 6% were pT1) and not available in 37%. Tumour grade was low, high, and unavailable in 49, 14, and 37%, respectively. The median follow-up was 30 months (range: 12-66), and 21 patients had a recurrence (60%). The median survival rate without recurrence was 10 months (95% CI [5-22]). Four patients underwent nephroureterectomy during follow-up. No patient died of disease progression. The main limitation was the limited length of follow-up.
CONCLUSIONS: Flexible endoscopic management can be advocated in selected cases of non-muscle invasive UUT-UCCs as an alternative to nephroureterectomy. Because of a high recurrence rate, long-term and stringent surveillance is needed, including iterative ureteroscopies at least every 3 months for 2 years.
