Objective: To analyses the residual tumor and staging after transurethral resection of bladder tumor (TURBT). Moreover, to analyze the recurrence and free survival patients who received treatment by re-transurethral resection of bladder tumor (RE-TURBT) and their complications.

Materials and Methods: A retrospective study from 35 patients operated by RE-TURBT between January 2010 and December 2018 was done. The patients in the present study were qualified by 1) incomplete resection from the first TURBT, 2) the detrusor muscle did not appear in specimen for high grade transition cell carcinoma, 3) any T1 lesion, or 4) large or multifocal lesion. The analysis of the residual tumor included staging, recurrence-free survival, and complication after RE-TURBT from the pathology report and follow up method.

Results: Thirty-five patients were included in this study. The average age of the patients operated by RE-TURBT was 69 years old, with a range of 44 to 87 years old. The presenting symptom was hematuria with gross hematuria in 28 patients (80%) and microhematuria in seven patients (20%). Twenty-five patients (71.4%) were male. The relative factor was smoking in 23 patients (65%) and coexisting with irritative voiding symptom in 11 patients (31.4%). The present study found that there was incomplete resection in 11 patients (31.4%), with under-staging in five patients and incomplete resection in six patients. There were 14 months recurrence-free survival and minor complication in RE-TURBT patients.

Conclusion: One third of the patients operated by RE-TURBT had unreasonable staging, especially in Ta high grade staging. This could change the treatment in two patients (5.7%), which found minor complication from RE-TURBT, and improve recurrence-free survival.
