Visualization of free peritoneal fluid during sonographic examination is often of considerable clinical importance. To determine the sensitivity of transvaginal sonography in the detection of this finding, measured amounts of isotonic saline were instilled into the abdominal cavities of 15 women undergoing diagnostic laparoscopy while a 5-MHz transvaginal probe was employed to view the pelvic contents. Small amounts of free fluid could be visualized easily in all the patients (mean +/- SD, 25.8 +/- 6.4 mL). Fluid was first seen in the cul-de-sac in 10 patients and in the adnexal region in 5. When fluid instillation was continued to a total volume of 200 mL, the pelvic viscera were distinctly outlined in all the patients, markedly enhancing visualization of the uterus, tubes and ovaries. Transvaginal sonography seems to be a sensitive and reliable method of detecting free peritoneal fluid. Instillation of fluid into the peritoneal cavity may be a clinically useful technique for enhancing the sonographic visualization of pelvic structures.
超声检查时观察到腹腔内有游离液体往往具有相当重要的临床意义。为了确定经阴道超声检查对这一发现的检测灵敏度，在15名接受诊断性腹腔镜检查的女性腹腔内注入定量的等渗盐水，同时使用5兆赫的经阴道探头观察盆腔内的情况。所有患者均能轻松观察到少量游离液体（平均值±标准差，25.8±6.4毫升）。10例患者首先在直肠子宫陷凹处见到液体，5例在附件区见到。当继续注入液体至总量达200毫升时，所有患者盆腔脏器轮廓清晰，子宫、输卵管和卵巢的显像明显增强。经阴道超声检查似乎是检测腹腔游离液体的一种灵敏且可靠的方法。向腹腔内注入液体可能是一种临床上有助于增强盆腔结构超声显像的有用技术。
