title: Transvaginal ultrasonography of nongynecologic pelvic lesions.
abstract: Transvaginal ultrasonography (TVUS) is one of the preferred imaging modalities in patients with gynecologic problems because of its high diagnostic accuracy, noninvasiveness, and wide availability. In endovaginal scanning, the problem of sonic attenuation is much less significant than with the transabdominal approach in the evaluation of the viscera in the true pelvis. Placement of high-frequency, high-resolution probes within the vagina allows accurate assessment of all anatomic structures of the female reproductive tract within the pelvis, and, incidentally, a variety of pathologic conditions affecting the intestinal tract, the urinary system, the pelvic walls, vessels, lymph nodes, and peritoneum can be assessed by this technique. In this article, we show the appearances of nongynecologic lesions of the female pelvis as imaged with TVUS and discuss the clinical indications to this kind of study and the role of TVUS in guiding interventional maneuvers through the vaginal vault. All endovaginal scans were taken with transducers at frequencies of 5.0-7.5 MHz.
