OBJECTIVES: To evaluate the preoperative risk factors for early intravesical recurrence after radical nephroureterectomy (RNU) in patients with upper urinary tract carcinoma (UTUC) according to the history of non-muscle invasive bladder cancer (NMIBC).
METHODS: We retrospectively evaluated patients who underwent RNU for UTUC between 2012 and 2022 at 14 hospitals. Early recurrence was defined as intravesical pathologically confirmed recurrence within 1 year after RNU. Patients who received single-dose immediate intravesical instillation (IVI) as prevention for intravesical recurrence were excluded. Using preoperative factors, we examined the risk factors for early intravesical recurrences in patients with and without a history of NMIBC. Death from any cause within 1 year after RNU was regarded as a competitive risk.
RESULTS: We included 504 UTUC patients who were treated with RNU. Among these patients, 126 (25.0%) had a history of NMIBC, whereas 378 (75%) did not. According to multivariate analysis, the presence of macrohematuria, positive cytology in self-voided urine, and performing diagnostic ureteroscopy prior to RNU were risk factors in patients without a history of NMIBC. On the other hand, an NMIBC diagnosis within 1 year prior to RNU and an extravesical approach for bladder cuff management were risk factors in RNU-treated patients with a history of NMIBC.
CONCLUSIONS: Early intravesical recurrence risk factors differ between UTUC patients with and without a history of NMIBC. Different stratification may be needed to predict intravesical recurrence risk in these two types of UTUC patients.
