膀胱エンドメトリオーシスの1例

Endometriosis of the bladder is an uncommon disease, but is common in gynecology. A 34-year-old woman visited us to be explored for the cause of microscopic hematuria and proteinuria, but gross hematuria had never been observed. Cystoscopic examination revealed a great number of pea size, hemispheric cysts on the trigone and the posterior wall of the bladder. Histopathological examination of the specimen taken by TU-biopsy showed vesical endometriosis. Danazol (17 alpha-Pregna-2, 4-dien-20-yno[2, 3-d] isoxazol-17-ol) was given to induce menostasia and thereafter endoscopic findings and subjective symptoms were improved. Seventy-five cases of vesical endometriosis in the Japanese were reviewed.
