title: [Clinical statistics of the bladder tumor--clinical and pathological aspects of 325 cases].
abstract: We analyzed 325 primary bladder tumor patients who were treated in our hospital during the past 15 years. There were 242 males and 83 females who were between 20 and 84 years old with an average age of 63 years old. The most frequent complaint was macroscopic hematuria in 76.9% of the patients (250/325). Cystoscopically, a single tumor was seen in 71%, the tumor was medium sized (1 to 3 cm) in 32%, and 56% were papillary tumors with a stalk. Histologically, 300 (92.3%) cases were transitional cell carcinoma. There were 42, 206 and 52 patients with grades 1, 2 and 3 transitional cell carcinoma and stage Tis, Ta, T1, T2, T3a, T3b, T2-4M1 and Tx were 2,46, 151, 30, 15, 16, 37 and 3 cases each. Transurethral resection was performed in 231 (71.1%), partial cystectomy in 6 (1.8%) and total cystectomy in 44 (12.5%) cases each.
