title: [Clinical statistics of the bladder tumor--transurethral resection cases].
abstract: Two hundred and thirty one patients who underwent transurethral resection of a bladder tumor (TUR-Bt) at our hospital during the past 15 years were analyzed. There were 176 males and 55 females, and the average age at the initial TUR-Bt was 62 years old. Histopathologically, 225 cases were of transitional cell carcinoma, 4 cases of papilloma and 2 cases of squamous cell carcinoma. Grading and staging of 225 transitional cell carcinoma cases revealed grades 1, 2 and 3 in 32, 132 and 21 cases, and stages Ta, T1, T2, T3 and T2-4M1 in 48, 135, 20, 17 and 11 cases, respectively. The frequency of TUR-Bt varied from 1 to 10 times. Among the 231 cases TUR-Bt was done once, twice and three times in 149 (64.5%) and 41 (17.8%), and 22 (9.6%) cases, respectively and the total number of TUR-Bt was 400 times. The duration of the TUR-Bt operation was from 5 min. to 160 min. (mean: 32.4 min.) and the resected weight of tumor between 0.5 g and 85 g (mean: 5.4 g). As a complication of TUR-Bt, TUR-fulguration was necessary to control postoperative bleeding in 7 cases (1.7%), and blood transfusion was required in 13 cases (3.3%) during TUR-Bt. Postoperatively blood transfusion was required in 8 cases (2%), intraperitoneal perforation in 2 cases (0.5%), extraperitoneal perforation in 6 cases (1.5%) and hyponatremia in 1 case (0.3%).(ABSTRACT TRUNCATED AT 250 WORDS)
