Objective:to probe the application on the hearing screening of the neonatus by transcience otoacoustic emission.methods: to undertakethe hearing screening of the neonatus by transcience otoacoustic emission of 2 100 neonatus from 2006.1~2006.12.results: 2 058 (98.4%) full-term newborn infants pass the transience otoacoustic emission once and 33(1.6%) full-term newborn infants can not pass it once.9(77.8%) premature infants pass the transience otoacoustic emission once and 2 premature infants can not pass it once.conclusion: the transience otoacoustic emission is worth to application because it has non-wound, fast, objective merit.

目的：探讨观察瞬态耳声发射在新生儿听力筛查中的应用。方法：对2006年1月~2006年12月2 100例新生儿利用瞬态耳声发射进行听力筛查的资料进行分析。结果：2 091例足月新生儿中，一次通过瞬态耳声发射进行听力筛查 2 058例，占98.4%，未通过33例，占1.6%，早产儿9例中，一次通过检测7例，占77.8%，未通过2例，占22.2%。全部未通过新生儿检查abr，确诊有异常15例，正常7例。结论：瞬态耳声发射具有无创伤、快速、客观、敏感度高等优点，值得在新生儿听力筛查中广泛推广应用。

objective to study the ct diagnosis of ureteral calculus at the distal end of ureter.methods 82 cases of ureteral caculus were examined by ct scanning.all cases were proved by clinical therapeutic results.results ureteral calculuses were showed as high density image in ct scanning.the ct values of the ureteral calculuses less than 7.5mm in diameter were beyond 83hu.the detection rate by ct was 96.3%.in all the 82 cases,ureteral with calculuses were found dilated and 69 cases with nephrohydrosis.in 13 cases with no nephrohydrosis,caculuses less than 3.8 mm in diameter were found.conclusion ct is the most valuable way to diagnose ureteral calculus at the lower end of ureter.appropriate methods of ct scanning are essential.

目的 回顾性分析输尿管膀胱入口处结石的ct诊断结果，评价其ct检查的临床应用价值。方法分析82例输尿管膀胱入口处结石的ct检查结果，所有病例均经尿道排石证实。结果输尿管膀胱入口处结石具有特征性的ct表现，即圆形或枣核状钙化高密度影，结石直径＜7.5mm，ct值≥83hu，ct确诊率96.3%。82例均发现病侧输尿管增粗，69例发现病侧肾盂少量积水，肾盂未见积水的输尿管膀胱入口处结石13例，其结石直径＜3.8mm。结论 ct检查输尿管膀胱入口处结石具有准确、无创、直观等优点，是诊断输尿管膀胱入口处结石不可替代的检查方法。

Objective:to explore the evaluation of color doppler ultrasonography in differential diagnosis of renal cystic disease.methods:theultrasonographic finds of cystic renal cancer in 4 cases,renal cyst in 30 cases, renal tuberculosis in 3 cases,nephropyosis in 8 cases,renal hydatid in 2 cases were analyzed.compared with each other in size,shape,edge, echo of cyst wall and cyst water,intracapsular membrane,blood flood.results:two-dimensional and color ultrasonography are helpful in showing the characteristic of structure and blood flow.the signal of blood flow can be found in cystic wall.node of cystic wall and intracapsular membrane of cystic renal cancer.the rate ofintracapsular membrane and node of cystic wall is higher than nephropyosis,renal tuberculosis and cystic renal disease.

目的：探讨彩色多普勒超声在肾脏囊性病变鉴别诊断中的价值。方法：对临床和病理证实的4例囊性肾癌，8例肾脓肿，2例肾包虫，3例肾结核，30例肾囊肿的二维超声及彩色多普勒超声表现进行了分析，对每例病灶的大小、形态、边界、囊壁回声、囊液回声、囊内分隔及彩色血流的有无、性质进行比较。结果：二维超声和彩色多普勒超声可以反映肾脏囊性病变的结构特征及血流特征。
