Transvaginal sonography has become an invaluable technique for examining the uterus, adnexa, and other nongynecologic structures in the pelvis because it provides better spatial resolution than transabdominal sonography [1]. Transvaginal sonography is a technique that complements manometric urodynamic examination by permitting a precise study of periurethral soft tissue. However, the principal disadvantage of transvaginal sonography is the distortion it provokes in vesicourethral anatomy [2]. Furthermore, transvaginal sonography cannot be used in small girls, virgins, and women with narrow vaginas, nor can it be used in assessing incontinence and other voiding dysfunctions because of direct effects on the physiology of the urinary tract caused by the probe itself [3]. Translabial sonography, which we have routinely used since 1990 [4], is an excellent alternative means of examination for these patients and for disorders of the lower urogenital tract. We have used translabial sonography in different types of incontinence. To learn more about the physiology of micturition, using translabial sonography, we let patients micturate not only in a recumbent position but also standing while straining and coughing. The latter position simulates a provocative cystometry. In this paper, we describe the translabial sonographic technique and some of the disorders we have encountered.
经阴道超声检查已成为检查子宫、附件及骨盆内其他非妇科结构的一项重要技术，因为它比经腹超声检查具有更好的空间分辨率[1]。经阴道超声检查是一种通过对尿道周围软组织进行精确研究来补充压力性尿动力学检查的技术。然而，经阴道超声检查的主要缺点是它会引起膀胱尿道解剖结构的变形[2]。此外，经阴道超声检查不能用于小女孩、处女以及阴道狭窄的女性，也不能用于评估尿失禁和其他排尿功能障碍，因为探头本身会对尿路生理产生直接影响[3]。自1990年以来我们一直常规使用的经阴唇超声检查，是这些患者以及下泌尿生殖道疾病的一种极好的替代检查方法。我们已将经阴唇超声检查用于不同类型的尿失禁。为了更多地了解排尿生理，我们让患者不仅在卧位排尿，还在站立时用力和咳嗽时排尿，使用经阴唇超声检查。后一种体位模拟激发性膀胱测压。在本文中，我们描述经阴唇超声检查技术以及我们遇到的一些疾病。
