The qualitative and quantitative effects of bladder and vaginal balloon volumes on the sonographic diagnosis of paravaginal defects were evaluated. Transabdominal ultrasound measurements were performed on patients with stage 4 prolapse and coexisting paravaginal defects (study group) as well as on nulliparous patients without prolapse or paravaginal defects (control group). Paravaginal defects were measured, first without a water-filled condom in the vagina, and then sequentially with a 30, 60 and 90 ml water-filled balloon in the vagina at bladder volumes of 150 and 300 ml. Paravaginal defects were detected on transabdominal ultrasound in both groups. In both the study and the control groups the size of the paravaginal defect was directly related to the size of the balloon placed in the vagina (P<0.0001). There were no significant differences in the size of the paravaginal defects measured at a bladder volume of 150 ml compared to those measured at 300 ml. We conclude that transabdominal ultrasound is not useful in detecting paravaginal defects.
评估了膀胱和阴道球囊容积对阴道旁缺陷超声诊断的定性和定量影响。对患有4期脱垂并伴有阴道旁缺陷的患者（研究组）以及未生育且无脱垂或阴道旁缺陷的患者（对照组）进行经腹超声测量。测量阴道旁缺陷，首先在阴道内不放置充水避孕套时进行，然后在膀胱容积为150和300 ml时，依次在阴道内放置30、60和90 ml的充水球囊进行测量。两组均通过经腹超声检测到阴道旁缺陷。在研究组和对照组中，阴道旁缺陷的大小均与放置在阴道内的球囊大小直接相关（P<0.0001）。膀胱容积为150 ml时测量的阴道旁缺陷大小与300 ml时测量的大小相比，无显著差异。我们得出结论，经腹超声在检测阴道旁缺陷方面并无用处。
