Back ground: rnBladder Cancer is the sixth most common cancer in the world, the seventh most common cancerrnin men, and the seventeenth most common cancer in women. Although the incidence of malignantrntumors of the bladder is increasing in developing countries, like Ethiopia, there is a lack of evidencernregarding the overall profile of bladder cancer in Ethiopia. rnObjective: To asses the demography, clinicopathology and treatment patterns of urinary bladderrncancer attending at oncology department and Urology unit of Tikur Anbessa Specialized Hospital,rnAddis Ababa, Ethiopia during the study period. rnMethods: An institution based descriptive cross-sectional study was conducted in TASH,rndepartment of Oncology and Urology unit, Addis Ababa, Ethiopia, and comprised medical records rnrelated to urinary bladder tumors between September 2018 and August 2021. rnResults: Of 158 cases, 81% were of males while 19% were of females making a male to femalernratio of 6.74:1. The mean age was 57.41Â±13.662 years (ranged from 22 to 88years). Hematuria rnwas the most common presenting symptom occurring in 143 (90.5%). Transitional cell carcinomarn(urothelial carcinoma) was the most common histology which accounted 87.4% followed byrnSquamous cell carcinoma (6.3%), adenocarcinoma (1.9%), sarcoma (1.3%) and mixed histologyrnvariants (1.3%). Overall, 45.6% was non-muscle invasive, 37.3% was muscle invasive and thernremaining 17.1%was metastatic at presentation. Majority of patients were treated with radicalrnintent. TURBT was the most commonly practiced type of treatment. Intravesical chemotherapy,rnperioperative chemotherapy and cystectomy were rarely practiced as compared with standardrnguidelines and text books. rnConclusion: The most common type of bladder cancer in TASH is TCC. Bladder tumor is morernfrequent in men than in women. Hematuria was the most common presenting symptom. The rncommonest procedure for bladder tumors was TURBT which is the golden standard for nonmusclerninvasiverntumors.
