Objectives: In this study, the epidemiological analysis of the bladder cancers was performed accompanied by the known environmental factors. Materials and methods: In this retrospective study, pathology archival materials of 420 patients (350 men (83.4%) and 70 women (16.6%) consisting of bladder by transurethral resection, cystectomy and cystoprostatecto­my specimens, histopathologically diagnosed as urothelial carcinoma and papillary urothelial neoplasia with low malignant potential, were included. For bladder carcinomas, the parameters such as tumor types, age, sex, and invasiveness of tumor were evaluated and analyzed. Results: In the study, it was found that 24.7% of papillary urothelial neoplasia with low malignant potential, 46. 1% of low-grade urothelial carcinoma, and 29.0% of high-grade urothelial carcinoma. The rate of bladder urothelial carci­nomas was 5 times greater in men than in women. In addition, the high-grade papillary urothelial carcinoma was seen more frequently in men than in women (31.2% and 23.1% respectively), while low-grade papillary urothelial carcinoma was seen more frequently in women than in men (32.9% and 18.5% respectively).
