Upper tract urinary carcinoma (UTUC) and bladder cancer (BCa) share similar biological, histological and pathological characteristics. These resemblances could explain the high rate of synchronous and metachronous tumors affecting both upper urinary tract and bladder. In patients affected by primary UTUC bladder recurrence is quite common and it represents one of the major concerns during the follow-up of patients who underwent radical nephroureterectomy. Conversely, UTUC recurrence after primary non-muscular invasive BCa is a relatively rare event. Moreover, there is no clear evidence on whether the use of Double-J stenting as drainage in patients affected by BCa increases the risk of UTUC recurrence. The aim of the current study was to summarize the most recent evidence regarding the bladder recurrence after UTUC surgical treatment, and the UTUC recurrence after stent positioning in patients affected by primary BCa.
