Abstract: The study was designed to assess the urinary bladder carcinoma with respect of patient`s age, sex and stages and grades. A total of 100 cases of diagnosed (for last five years) patients (mean age 58.05±11.96 years) of urinary bladder carcinoma visiting various hospitals in private sector in Karachi were selected on the basis of their biopsies were seen for staging and grading of the tumor and the information obtained were correlated with each other. From the total cases males were 79% and females were 21%. The most common age group involved in this malignancy i.e., 38% was found to be 60-69 (64.5±6.36) years old. Most of the cases reported were from grade II (47%) and the second most common grade was grade III (36%). As far as staging is concerned, out of 100 cases only pT1 and pT2 were reported that were found to be 63 and 37%, respectively. It can be concluded that, male to female ratio was remained 3:1. The prevalence of cancer increased with age and reached at maximum at the age group of 60-69 years. Biopsies showed the most common grade i.e., grade II (47%) and most common stage i.e., pT1 (63%).
