Histopatological Study of Urinary Bladder Tumors- A 10 Year Study

Urinary bladder cancer is the sixth most common cancer worldwide and the fourth most common cancer in men. Histopathology is an important tool to grade and type different types of bladder tumors. The aim of this study is to evaluate and grade different types of bladder tumors along with presence or absence of invasion over a period of 10 years. This is a prospective study of 261 cases presenting with bladder growth operated in the Urology Department J L N Medical College Ajmer between January 2006 and December 2015. Histopathological examination of the biopsies submitted in pathology department was done and typing and grading of the tumors was done using WHO/ISUP Grading System. Results showed that the maximum prevalence of bladder tumors was seen between the age group of 61 to 70 years. (35.2 %) with a male preponderance (82.3 %). The commonest type of carcinoma was Urothelial carcinoma (92.7 %). The commonest Urothelial tumour was non-invasive high grade papillary carcinoma. (29.1 %).
