According to literature and to our experiences sonography should be the first investigation of the lower urinary tract in children, if there is suspicion of obstruction or malformation. In many cases the localisation of obstruction or the diagnosis of malformation can be found. Furthermore by sonographic follow-up studies of ureter obstructions by tumors, by concrements or after surgery, the normal radiographic investigations like urography or retrograde pyelography can be reduced. Sonography is a valuable enrichment for investigations of functional and morphological changes of the urinary bladder, especially for the classification of bladder tumors: whereas the diagnosis of urethral diseases still is found by clinical investigations and conventional radiological procedures.
根据文献及我们的经验，如果怀疑存在梗阻或畸形，超声检查应作为儿童下尿路的首选检查方法。在许多情况下，可以确定梗阻的部位或畸形的诊断。此外，通过对肿瘤、结石或手术后输尿管梗阻的超声随访研究，可以减少诸如尿路造影或逆行肾盂造影等常规影像学检查。超声检查对于膀胱功能和形态学变化的研究是一种有价值的补充，特别是对于膀胱肿瘤的分类：而尿道疾病的诊断仍通过临床检查和传统放射学方法进行。
