A simple method for clear visualization of the vagina during ultrasound scanning is described. A sealed cylinder, filled with water, is introduced into the vagina. This device, used when the urinary bladder is full, improves visualization of the pelvic organs and facilitates interpretation of the scans. The technique may be employed during all stages of pregnancy, provided there is no bleeding or dilatation of the cervix.
本文描述了一种在超声扫描时清晰显示阴道的简单方法。将一个装满水的密封圆柱体插入阴道。当膀胱充盈时使用该装置，可改善盆腔器官的可视化并便于扫描结果的解读。只要没有出血或宫颈扩张，该技术可用于妊娠的各个阶段。
