RESUMO
We reviewed 80 cases of hemorrhagic radiation cystitis(HRC) treated in the Department of Urology, Korea Cancer Center Hospital from March, 1985 to July, 1990. The results were obtained as follows. 1. Primary underlying diseases were 1 bladder tumor and 79 cervix cancers. Main presenting symptoms and signs on hospitalization were gross hematuria, passage of blood clots and vesical irritability symptoms. 2. The range of radiation doses to the bladder was from 5,000 to 11,086 cGy and the ratio of cases receiving irradiation over 7,000 cGy was 56.3 %(45 among 80 cases). Time elapsing between termination of radiation therapy and occurrence of HRC was ranged from 1 month to 14.5 years. 3. We performed histopathologic examination in 22 cases. Microscopically, diffuse mucosal edema and ulceration, vascular telangiectasia, submucosal hemorrhage were observed. The areas of ulceration contained acute inflammatory cells at their base and the lamina propria was hyalinized with enlarged atypical fibroblasts and endothelial cells. Of 22 cases, 4 cases of the secondary neoplasia (1 case of transitional cell papilloma, 2 cases of transitional cell carcinoma(TCC) and 1 case of adenocarcinoma), 1 case of TCC of recurrent bladder tumor and 1 case of recurrent cervix cancer invading bladder were observed. 4. Hematuria was controlled in 57 cases receiving transurethral fulguration(TUF), but repeated TUF (2-4 times) was performed for recurrent severe gross hematuria in 7 cases and the ratio of cases requiring re-hospitalization due to recurrent severe gross hematuria after TUF was 16.4%. Of complications due to treatment of HRC, no significant complication was found after TUF, but incontinence due to contracted bladder was occurred in 1 case of 3% formalin instillation.
