利尿B超在诊断重复肾双输尿管合并输尿管开口异位中的应用

采用利尿Ｂ超诊断重复肾双输尿管合并输尿管开口异位８例，结果令人满意。普通Ｂ超多不能显示正常输尿管。利尿可以使输尿管扩张（上、下半肾输尿管均扩张），操作者可以在同一切面上同时见到重复肾及双输尿管，而且可以在膀胱后方发现扩张的输尿管不进入膀胱而向尿道方向延伸。正常输尿管呈纤细狭长的回声带，开口于膀胱三角区。小儿重复肾双输尿管合并输尿管开口异位的诊断有时很困难。利尿Ｂ超为该病的诊断提供了确切的依据，并且简便易行，为超声诊断提供了新的方法与手段。

Diuresis Ultrasound Diagnosis or Duplex Kidney with Double Ureters and Ectopic Ulsteral Oririce

Diurests ultrasound was used to diagnose duplex kidney with double ureters and ectopic ureteral orifice in 8 cases.The result was satisfactory.In most cases the conventional ultrasound examination cann't show the normal ureter.Diuresis caused the ureter to be dilated(both upper and lower ureter).The duplex kidney and double ureters could be shown at same plane simultaneously.The ectopic dilated ureter did not enter into the bladder but extended along with.the urethra behind the bladder.While the normal ureter showed as a slender and fine echo band, emerged into the trigone of bladder.The diagnosis of this abnormality in children sometimes may be very difficult.Diuresis ultrasound provides a reliable metod to detect this disease.The method is simple, easy to perform and also throws new light on ultrasound diagnosis.
