To evaluate the diagnostic accuracy of transvaginal ultrasonography in detecting and measuring free pelvic fluid.
Eighty-two patients undergoing diagnostic or therapeutic laparoscopy at a tertiary care center were prospectively assessed before surgery by transvaginal ultrasound. Free pelvic fluid was measured in two ultrasonographic planes. These measurements were compared to the volume of fluid aspirated during laparoscopy.
The mean volumes reported for transvaginal ultrasound were significantly lower than those observed at laparoscopy (mean milliliters +/- SEM, 2.54 +/- 0.5 versus 9.42 +/- 1.3, P < .001). The smallest volume of free pelvic fluid that was consistently detected by ultrasound was 8 mL. Whenever no fluid or < 1 mL was detected by transvaginal ultrasound, a small volume of fluid was found at laparoscopy (mean milliliters +/- SEM, 1.6 +/- 0.47). The sensitivity of transvaginal ultrasound was 83% and specificity was 69%.
Transvaginal ultrasound is a sensitive method of detecting the presence of > 8 mL of free pelvic fluid and therefore is an important diagnostic tool in the assessment of pelvic pathology associated with increased peritoneal fluid.
评估经阴道超声检查在检测和测量盆腔游离液体方面的诊断准确性。
在一家三级医疗中心，对82例行诊断性或治疗性腹腔镜检查的患者在手术前进行经阴道超声前瞻性评估。在两个超声平面测量盆腔游离液体。将这些测量结果与腹腔镜检查时吸出的液体量进行比较。
经阴道超声报告的平均液体量显著低于腹腔镜检查时观察到的量（平均毫升数±标准误，2.54±0.5对9.42±1.3，P<.001）。超声始终能检测到的最小盆腔游离液体量为8毫升。当经阴道超声未检测到液体或检测到的液体量<1毫升时，腹腔镜检查发现有少量液体（平均毫升数±标准误，1.6±0.47）。经阴道超声的敏感性为83%，特异性为69%。
经阴道超声是检测盆腔游离液体量>8毫升的一种敏感方法，因此是评估与腹膜液增加相关的盆腔病理情况的重要诊断工具。
