Histopathological Study of Urinary Bladder Tumors at Tertiary Care Centre - A Retrospective Study of 2 Years

Background: The main aim of this study was to analyze the histomorphological patterns of urinary bladder tumours in relation with age and sex and to analyse the relation between stage and grade of urothelial tumors. Methods: This is a retrospective study of 2 years.90 cases of bladder tumours were studied in the age group between 30 - 80 years. The consecutive cases from both TURBT biopsies and cystectomy specimen were included in the analysis. Result: The maximum no. of cases was in the eighth decade. Low grade urothelial carcinoma constituted the maximum number of cases (40 %). Muscle invasion was seen more commonly in high grade carcinoma. Conclusion: Urothelial carcinoma is the most common bladder tumour with male preponderance, most common age group is 8thdecade. The inclusion of smooth muscle in the biopsy specimen needs tobe emphasized as there is direct correlation between advancing tumour grade and muscle invasion.
