Purpose : To evaluate the residual tumor rate and location in second transurethral resection after Ta high-grade bladder cancer.
Patients and methods : Patients with Ta high-grade bladder cancer were evaluated retrospectively. Thirty-nine patients had Ta high-grade bladder cancer and received a second TUR at our institution.
Results : Ten of the 39 (25.6%) patients had residual cancer. Tumor diameter of less than 10 mm was a predictive risk factor for residual cancer at the 2nd TUR in multivariate analysis (p=0.009). Seven of the 10 (70%) patients with residual cancers were detected at the edge of the initial TUR scar, and 2 patients cancers were found at the edge of the 2nd TUR resection lesion.
Conclusion : Residual cancers were mostly located around the initial and 2nd TUR resection areas. Wide resection should be performed in the 2nd TUR for a Ta high-grade tumor even if the tumor is small at the initial TUR.
