A 40-year-old woman suffered from severe bladder endometriosis involving the bladder trigone and left urethral orifice. Severe dysmenorrhea, lower urinary tract symptoms (pollakiurea and discomfort while urinating) were the chief complaints. The findings of magnetic resonance imaging (MRI) and transurethral resection of the tumor (TUR-BT) confirmed the diagnosis and revealed the extent of the lesion. Surgical resection of the lesion was not performed because of the difficulty anticipated for complete resection and the fear of affecting the bladder function after the resection. The administration of leuprolide acetate followed by genogest successfully reduced the tumor size and alleviated the symptoms for 14 months. Partial cystectomy is essential for complete remission and is indicated for patients who desire pregnancy. However, a high incidence of recurrence after resection of the tumor that involved the bladder fundus has been reported. Hence, it is important to individualize the treatment strategy for bladder endometriosis by accurately evaluating the location and the extent of the lesion.
