Urothelial malignancy of urinary bladder is the most common malignancy of urinary tract. It is the sixth most common malignancy in India. Few literatures are available on epidemiological data of urinary bladder cancer at eastern part of India. The aim of our study is to provide the epidemiological scenario and detecting risk factors contributing to the urothelial carcinoma of bladder in the southern part of West Bengal. It is a prospective observational study. All data regarding the urinary bladder tumors were recorded in Case Record Proforma (CRP) of Bladder Tumour Registry, department of Urology, Calcutta National Medical College, Kolkata, from June, 2015 to May, 2018. Initially total 124 patients were enrolled for the study; later only 120 patients were included as they had biopsy proven urothelial carcinoma on histopathological report of tissues obtained by transurethral resection. In our study, males were more frequently (71.6%) affected than females (28.33%) and urothelial malignancy was more prevalent in Hindus. On blood group analysis, disease was more prevalent in individuals with ‘B’ positive blood group. Tobacco smoking was revealed to be an important causative factor (67.5%). Low socioeconomic class (80.83%), less water intake (56.67%) were important contributory factors. Intake of alcohol and caffeine are probably confounding factors. High grade tumors with the high stage malignancy were more prevalent among aged patients. The study suggests that epidemiological survey using bladder tumor registry should be incorporated in the evaluation of bladder cancer to formulate any disease control programme.
