Leiomyoma of the urinary bladder treated by transurethral resection: a case report

A 59-year-old woman with complaints of pollakisuria and dysuria, was referred to our hospital. Magnetic resonance imageing (MRI) revealed a tumor, about 59 mm in diameter. Cystoscopy showed a submucosal tumor covered with a normal mucosa. Histological diagnosis was leiomyoma of the urinary bladder by transurethral biopsy. So we performed complete resection of the tumor. To our knowledge, 30 cases of leiomyoma of the urinary bladder by transurethral resection have been reported in the Japanese literature.
