Transvaginal ultrasonography of female urethral carcinoma treated with radiation therapy: report of two cases.
Female urethral carcinoma is an uncommon disease that often cannot be detected precisely by computed tomography and MR imaging. Therefore, we applied transvaginal ultrasonography (TVUS) using a real-time scanner with 7.5 MHz transducer to two female patients with urethral carcinoma who were treated with radiation therapy, to evaluate tumor extension and radiation response. Sagittal images of the urethra along a 3.0 cm long axis were obtained through the vaginal anterior wall with penetration of about 4.0 cm. TVUS demonstrated the tumor locations and dimensions, especially whether the tumor was located in the distal half of the urethra or involved the proximal urethra. TVUS was also useful for the assessment of radiation response.
