Clinical investigation reports upper tract urothelial carcinoma risk after double-J stenting in bladder cancer, highlighting concerns regarding tumour seeding.
It is controversial whether the use of a double-J stent (DJ) in patients with bladder cancer before radical cystectomy (RC) increases the risk of tumour seeding in the upper tract and thus the risk of metachronous upper tract urothelial carcinoma (UTUC). The aim of our study is to investigate the risk of upper tract recurrence after RC in patients previously managed with a DJ stent.
