“…Risk factors such as tumor configuration [8], tumor multiplicity [6,7,9,10], tumor stage [6,7,11,12], tumor grade [5,13], tumor location [5,14,15], patient gender [8,16,17], postoperative adjuvant systemic chemotherapy [16,18], and preoperative voided urine cytology [15,19] have been proposed, but the results remain controversial and no reliable conclusions could be drawn to aid surveillance strategies. Therefore, a clear knowledge of potential predictive factors for bladder recurrence in UUT-UC would allow better prognostic evaluation and aid surveillance strategies.…”
