Purpose: To evaluate factors related to the recurrence of TCC(transitional cell carcinoma) in the urinary bladder after transurethral resection of bladder tumor(TUR-BT). Materials and Methods : We retrospectively reviewed 54 patients in whom TCC (transitional cell carcinoma) after TUR-BT had been confirmed. Recurrence was evaluated by US, CT, cystoscopy and urine smear during the follow-up period of 6 months. The multiplicity, shape, size, and calcification of TCC, as revealed by radiologic studies, were evaluated retrospectively before TUR-BT. After TUR-BT, the histologic grade and pathologic stage of TCC were evaluated. Results : According to the multiplicity of TCC, the recurrence rate was 66.7% in the multiple type and 28.6% in the single type(p=0.039);according to shape, this rate was 61.5% in the sessile type and 29.3% in the pedunculated type(p=0.0505), and according to mass size, the rate was 41.7% in tumors more than 3cm in diameter and 35.7% in tumors less than 3cm(p=0.706). In the presence of calcification, the recurrence rate was 40.0% and in its absence, this rate was 36.7%(p=0.885). Pathologically, the higher the grade and stage of TCC, the higher the recurrence rate(respectively p=0.010 and 0.041). Conclusions : Radiologically, multiple and/or sessile type TCC had a higher recurrence rate than the single and/or pedunculated type. Pathologically, when the grade and stage of bladder tumor were higher, recurrence rates were higher.
