    • 摘要: 目的 探讨儿童先天性肾积水(CH)早期筛查的临床意义及对其早期随访的临床价值.方法 选择2019年8月1日至2020年7月31日,在中山市博爱医院产科出生,于生后7 d内接受泌尿系统超声筛查,并且临床病例资料完整的4811例新生儿为研究对象(男性新生儿为2566例,女性为2245例).对其中符合C H诊断标准者进行随访,观察CH患儿生后6个月肾积水部位及分度变化、并发症发生情况.本研究遵循的程序经中山市博爱医院伦理委员会批准(审批文号:KY-2019-002-17),与受试儿监护人均签署泌尿系统超声筛查知情同意书.结果 ①本组4811例受试儿中,生后7 d内新生儿泌尿系统超声筛查结果提示,先天性肾脏尿路发育异常(CAKUT)者为268例(5.6%),其中CH患儿为248例.本组CAKUT新生儿的肾积水阳性率为92.5%(248/268).248例C H患儿中,男性患儿为164例,女性为84例;轻、中、重度肾积水患儿分别为213、19、16例.②本组4811例受试儿中,产前胎儿超声筛查肾积水阳性率为2.3%(111/4811),显著低于生后7 d内新生儿泌尿系统超声筛查阳性率(5.2%,248/4811),并且差异有统计学意义(χ2=99.408、P<0.001).③对248例CH患儿随访至3个月时,肾积水恢复正常患儿为125例(50.4%),好转为37例(14.9%),维持原状为61例(24.6%),加重为18例(7.3%),7例发生发热性尿路感染(UTI).④随访至6个月,213例轻度肾积水患儿中,170例肾积水恢复正常,4例加重;19例中度肾积水患儿中,11例恢复正常或好转;16例重度肾积水患儿中,无一例恢复正常,12例好转.15例发生发热性UTI.对本组16例重度肾积水和4例肾积水加重患儿进行磁共振泌尿系水成像(MRU)或多层螺旋CT尿路造影(CTU)检查发现,先天性肾盂输尿管连接部梗阻(UPJO)和尿道瓣膜症(PUV)分别为15、1例,无一例患儿由单侧肾积水发展为双侧.⑤6个月的随访期内,248例CH患儿中,19例(7.7%,19/248)出现发热性UTI中,男性为14例,女性为5例.16例重度肾积水患儿的发热性UTI发生率为31.2%(5/16),显著高于轻度肾积水患儿(6.6%,14/213),并且差异有统计学意义(χ2=411.776、P<0.001).这19例出现发热性UTI患儿中,对13例进行MCU检查,7例被确诊膀胱输尿管反流(VUR),均为轻度肾积水患儿.⑥其中12例重度肾积水患儿接受外科手术后好转,5例VUR患儿随访结束时,尚需继续预防性长期口服小剂量抗菌药物治疗.对重度肾积水、肾积水加重和发生并发症患儿进行肾小球滤过率(eGFR)等检查,均提示正常.结论 生后新生儿早期泌尿系统超声筛查CH具有重要临床意义.多数轻、中度肾积水患儿于生后6个月内可自行恢复正常,重度及随访中呈加重趋势的轻、中度肾积水患儿多为因发生UPJO所致.

    • 摘要: 目的探讨高频超声对肉芽肿性乳腺炎的诊断价值。方法回顾性分析106例经手术或粗针穿刺活检病理确诊为肉芽肿性乳腺炎的超声表现,肉芽肿性乳腺炎依据超声表现不同可分为低回声结节(或)肿块型、弥散分布型、混合回声型。结果106例肉芽肿性乳腺炎共115个病灶中,高频超声诊断肉芽肿性乳腺炎良恶性的准确率为62.6%,其中低回声结节(或)肿块型为31.5%,弥散分布型为71.4%,混合回声型为81.6%。结论肉芽肿性乳腺炎超声声像图缺乏特异性,其良恶性诊断正确率与超声分型有关,综合评价分析有助于提高疾病诊断的准确率。

    • 摘要: 精索静脉曲张是青年男性的常见疾病之一,主要以左侧多见,严重者可引起睾丸发育不良和男性不育,发病机制目前仍不是很明确,其治疗的方法和时机的选择也存在争议.彩色多普勒超声在精索静脉曲张的诊断中应用广泛.治疗精索静脉曲张分药物治疗和手术治疗.常用的手术方法有传统开放手术(腹股沟管精索静脉结扎术、腹膜后精索静脉高位结扎术)、腹腔镜/机器人下精索静脉高位结扎术、精索内静脉栓塞术、显微外科外环口精索静脉结扎术.但各方法的疗效及并发症也存在许多争议.现就近年来有关精索静脉曲张诊治的进展作一综述.

    • 摘要: 目的 通过受试者工作特征(receiver operating characteristic,ROC)曲线分析评估经颅彩色多普勒超声(transcranial color-coded sonography,TCCS)和磁共振血管成像(magnetic resonance angiography,MRA)对于单侧大脑中动脉(middle cerebral artery,MCA)狭窄的诊断价值.方法 选取行 TCCS、MRA 及头颈部 CT 血管成像(CT angiography,CTA)3种检查方法的单侧 MCA 狭窄患者127例,以 CTA 检查结果为标准,其中137根正常MCA,117根狭窄者,按程度分为正常、轻度狭窄、中度狭窄及重度狭窄,然后进行 ROC 曲线分析.结果 TCCS与MRA在诊断单侧 MCA狭窄的曲线下面积分别为0.989(95%CI 0.967~0.998)、0.991(95%CI 0.970~0.999),差异无统计学意义(P>0.05);在诊断单侧MCA轻度-中度狭窄的曲线下面积分别为0.959(95%CI 0.796~0.941)、0.882(95%CI 0.894~0.989),MRI诊断价值高于TCCS,差异有统计学意义(P0.05).结论 TCCS和 MRA 2种检查作为筛查单侧 MCA 狭窄方法均具有较高的诊断价值,尤其在诊断轻度-中度狭窄分级上,MRA诊断价值高于TCCS.%Objective To evaluate transcranial color-coded sonography(TCCS)and magnetic resonance angiography(MRA)in screening of diagnosing unilateral middle cerebral artery(MCA)stenosis by using receiver operating characteristic(ROC)curve analysis.Methods A total of 127 patients with unilateral middle cerebral artery(MCA)stenosis were enrolled in this study.TCCS,MRA and CT angiography(CTA)of head and neck were performed in all patients. Based on CTA results,1 3 7 normal MCA of root in the control group,1 1 7 MCA with stenosis were divided into 4 categories:normal,mild stenosis,moderate stenosis and severe stenosis, then the data were evaluated using ROC curve analysis.Results The two diagnostic methods of TCCS and MRA were of high value in the diagnosis of stenosis in the unilateral MCA.The area under the curve of TCCS and MRA were 0.989(95%CI 0.967-0.998)and 0.991(95%CI 0.970-0.999),and the area under the curve was not statistically significant(P>0.05).The diagnostic value of MRI was higher than that of TCCS in the diagnosis of mild to moderate stenosis in the unilateral MCA.The area under the curve was 0.959(95%CI 0.796-0.941)and 0.882(95%CI 0.894-0.989)respectively,and the area under the curve was statistically different(P0.05).Conclusion Both TCCS and MRA tests have high diagnostic value as a method for screening the arterial stenosis in the unilateral MCA,especially in the diagnosis of mild to moderate stenosis,the diagnostic value of MRA is higher than that of TCCS.

    • 摘要: 目的 研究急性闭合性跟腱断裂病人下肢深静脉血栓(DVT)的发生及相关情况.方法 连续收集2014年1月-2016年8月我院收治的急性闭合性跟腱断裂病人214例,其中男188例,女26例,年龄19~74岁,平均(38.7±11.3)岁.根据Kuwade分型将跟腱断裂分为Ⅰ、Ⅱ、Ⅲ、Ⅳ型.采用彩色多普勒超声检查作为下肢DVT的诊断标准,分析各型跟腱断裂病人下肢DVT的发生率、血栓检出时间,以及血栓范围分布情况.分别采用卡方检验和秩和检验比较不同跟腱断裂分型的血栓发生率和血栓检出时间.结果 本组病人DVT总发生率为10.7%,其中周围型(血栓累及腘静脉以下)DVT 22例,混合型(血栓累及全下肢深静脉)DVT l例.不同跟腱断裂分型间血栓发生率差异无统计学意义(P>0.05).不同跟腱断裂分型间血栓检出时间差异有统计学意义(P<0.05),Ⅰ+Ⅱ型跟腱断裂血栓检出时间最长,Ⅲ型次之,Ⅳ型检出时间最短.结论 急性闭合性跟腱断裂病人DVT相关检查不可忽视,及早发现及早采取预防措施可避免发展成为致命的中央型血栓.彩色多普勒超声可作为跟腱断裂后下肢DVT的首选检查方法.%Objective To investigate the incidence and related factors of deep venous thrombosis (DVT) in patients with acute closed Achilles tendon rupture.Methods A total of 214 patients with acute closed Achilles tendon rupture in our hospital from January 2014 to August 2016 were collected.There were 188 males and 26 females,aged 19-74 years,with an average age of 38.7±11.3 years.According to the Kuwade classification,the rupture of Achilles tendon was divided into Ⅰ,Ⅱ,Ⅲ,and Ⅳ types.Color Doppler ultrasonography was used as the diagnostic criteria for deep venous thrombosis of lower extremities to analyze the incidence of DVT of lower extremity,the time of thrombosis,and the distribution of thrombus.Chisquare test and rank sum test were used to compare the incidence of thrombosis and the time of thrombus detection among different types of Achilles tendon rupture.Results The total incidence rate of DVT was 10.7%,including peripheral DVT (the thrombus involved below the popliteal vein) in 22 cases,and mixed type DVT (the thrombus involved the entire lower extremity vein) in 1 case.There was no significant difference in the incidence of thrombosis among different types of Achilles tendon rupture (P>0.05).There was a significant difference in the mean time among the different types of Achilles tendon rupture thrombosis (P<0.05).The detection times of Type Ⅰ and type Ⅱ thrombosis were the longest,followed by the one of type Ⅲ,the detection time of type Ⅳ was the shortest.Conclusion In patients with acute Achilles tendon rupture complicated with deep venous thrombosis,related examination cannot be ignored.Early detection and early preventive measures can avoid the development of a central type of fatal thrombosis.Color Doppler ultrasound can be used as the first choice method for DVT of lower limbs after Achilles tendon rupture.
