输尿管结石的超声诊断

Ultrasound diagnosis of ureteral stones

目的针对急腹症病例,探讨超声在输尿管结石中的诊断价值。方法反复肾绞痛、血尿者结合病史及实验室检查,对拟诊为尿路结石的180例患者进行两侧肾、输尿管及膀胱的超声检查。结果超声诊断输尿管结石的180例中,160例有输尿管梗阻,15例无肾盂积液,结石最大者约0.8 cm,最小者约0.3 cm,位于膀胱壁内段150例,腹段20例,盆腔段10例。结论超声根据尿路梗阻声像、输尿管内强回声团块伴声影,对输尿管结石可以作出准确诊断。对肾盂无积液者,结合病史,有肾绞痛及血尿者,也能准确诊断。

Objective In cases of acute abdomen,of ultrasound in the diagnosis of ureteral stones.Methods Repeated renal colic,hematuria,combining history and laboratory examination,is proposed for the 180 patients with urinary stones,carried out on both sides of kidney,ureter and bladder ultrasound.Results Ultrasound diagnosis of ureteral calculi in 180 cases,160 patients with catheter obstruction,15 patients with no hydronephrosis,the biggest stone about 0.8vcm,the least 0.3vcm,located within a section of bladder wall 150 cases,20 cases of abdominal segment,pots in 10 cases.Conclusion Ultrasound audio and video according to urinary tract obstruction,ureter strong hyperechoic mass with acoustic shadow,and can make an accurate diagnosis of ureteral calculi.Of the pelvis were without water,combined with a history of renal colic and hematuria are also able to accurately diagnose.
