    AbstractThis study investigates the difference in overall survival rates after transurethral resection of bladder tumor between solitary and multiple bladder cancers, aiming to provide guidance for clinical practitioners. A retrospective analysis was conducted on 133 patients with bladder cancer who underwent transurethral resection of bladder tumor from April 2017 to October 2023, of which 112 patients had complete clinical and follow-up data. Clinical and follow-up data were collected, and the overall survival rates after surgery were compared between solitary and multiple bladder cancers. In this study, the recurrence rate after transurethral resection of bladder tumor was 23.21% (26/112), and the overall survival rate was 80.36% (90/112). The overall survival rate after transurethral resection of bladder tumor was 92.11% (35/38) in the solitary bladder cancer group and 74.32% (55/74) in the multiple bladder cancer group, with a statistically significant difference between the 2 groups (P = .025). The proportion of high-grade pathology was 7.89% (3/38) in the solitary bladder cancer group and 25.68% (19/74) in the multiple bladder cancer group after transurethral resection of bladder tumor, with a statistically significant difference between the 2 groups (P = .025). The mean tumor diameter after transurethral resection of bladder tumor was 2.76 ± 1.66 cm in the solitary bladder cancer group and 4.04 ± 3.17 cm in the multiple bladder cancer group, with a statistically significant difference between the 2 groups (P = .023). Univariate and multivariate regression analyses revealed that the number of bladder tumors is a risk factor for overall survival after bladder cancer surgery (P = .004). Multiple bladder cancers have a higher pathological grade, larger tumor diameter, and poorer prognosis after transurethral resection of bladder tumor compared to solitary bladder cancers. The number of bladder tumors is an independent risk factor for overall survival after bladder cancer surgery.Copyright © 2024 the Author(s). Published by Wolters Kluwer Health, Inc.
