When disease travels downstream: The effect of intravesical recurrences in patients treated for upper tract urothelial carcinoma

BJUI Compass, Volume 7, Issue 7, July 2026.
Abstract Background Treatment of upper tract urothelial carcinoma (UTUC) depends on risk stratification and tumour characteristics. Kidney‐sparing surgery (KSS) is preferred for low‐risk disease, whereas radical nephroureterectomy (RNU) is the standard for high‐risk UTUC.

Who needs further evaluations to diagnose upper urinary tract urothelial cancers among patients with abnormal findings by enhanced CT?

Asian Journal of Urology, 2016
Objective: We evaluated who would need further evaluations such as retrograde pyelography (RP) and/or ureteroscopy to diagnose upper urinary tract urothelial cancers (UUTUCs) when abnormal findings for the upper urinary tract (UUT) were detected by ...
