Aim: Bladder cancers are the ninth most common malignancies in the world. These are the most common malignancies of the urinary tract. The most common histological type of this cancer is urothelial cell carcinoma. It has very high rates of recurrence and invasion. The aim of this study is to evaluate the results of bladder TUR and re-TUR cases in terms of invasion and histological grade, to share the results with the literature, to determine the prognosis of patients and to contribute to the clinical follow-up and treatment. Material and Method: Pathology archive of Erzincan Binali Yıldırım University was used in this study. Cases with urothelial carcinoma of the bladder were included in the study. A total of 177 cases who underwent bladder TUR between 2013–2018 were examined. Sections from the paraffin blocks of these cases were evaluated with Hematoxylin-Eosin staining. Re-TUR results were compared with the first TUR diagnosis. Results: 153 of the patients were male and 24 were female. In 103 cases, the tumor was high-grade and 74 patients had low-grade tumor. Sixty-six cases had non-invasive urothelial carcinoma. Lamina propria invasion was detected in 102 cases and muscularis propria invasion in 9 cases. 46 (26%) cases had a recurrence. Recurrence rates were significantly higher in the cases with high-grade tumor and in the invasive cases. 3 (27.2%) of the recurrent 11 low-grade cases had a high-grade tumor in the recurrence material. The invasion was detected in 2 (18.2%) of 11 noninvasive cases. Conclusion: Bladder TUR and re-TUR results were shared with the literature. It was emphasized that if there is invasion and histological grade changes in the recurrence and the first TUR diagnosis, treatment and follow-up of patients should be re-planned.
