The author endeavours to detail the technical modalities which can be used to avoid uncertainty in urodynamic sonography, and to obtain easily reproducible quality imaging. The 5 major techniques (transparietal, transperineal, introital, endovaginal and endorectal) are compared. The artifacts generated are described. A choice between these different techniques is performed as a function of the methodological advantages specific to each of them and the clinical applications contemplated by the sonographer. The characteristics of the "ideal" equipment are defined to help the sonographer-to-be to choose his or her equipment with full awareness of the facts (characteristics of the probe, emission frequency, settings by the sonographer, automatic image freeze during coughing). The methodology is described in detail and widely illustrated: position of the patient, choice of the section plane, choice of the reference system, location of the urethra, and definition of the vesical neck, maintenance of the probe position during effort or free movement, degree of vesical fullness, choice of the parameters. Some difficulties can be linked to the patient's anatomical characteristics (vaginal scar, short or narrow vagina, twisted urethra,...); ways to avoid them are briefly described.
作者致力于详细阐述可用于避免尿动力学超声检查中不确定性并获得易于重复的高质量成像的技术方法。对五种主要技术（经腹、经会阴、经阴道开口、经阴道和经直肠）进行了比较。描述了所产生的伪像。根据每种技术特有的方法学优势以及超声检查人员所考虑的临床应用，在这些不同技术之间进行选择。定义了“理想”设备的特性，以帮助未来的超声检查人员在充分了解实际情况（探头特性、发射频率、超声检查人员设置、咳嗽时自动图像冻结）的情况下选择其设备。详细描述并广泛说明了该方法：患者体位、切面选择、参考系统选择、尿道定位、膀胱颈定义、用力或自由移动时探头位置的保持、膀胱充盈程度、参数选择。一些困难可能与患者的解剖特征（阴道瘢痕、阴道短或窄、尿道扭曲等）有关；简要描述了避免这些困难的方法。
