Preoperative hydronephrosis and diabetes mellitus predict poor prognosis in upper urinary tract urothelial carcinoma

Abstract

Tumour location is not a factor influencing RFS, except in the pT2 stage. However, severe hydronephrosis is associated with a higher recurrence in UUTUC. Also, DM is related to disease recurrence. Further prospective studies are needed to establish the prognostic significance of DM in large populations.
