【摘要】：目的探討術(shù)前超聲預(yù)判睪丸扭轉(zhuǎn)患兒轉(zhuǎn)歸的應(yīng)用價(jià)值。方法回顧性分析45例兒童睪丸扭轉(zhuǎn)的臨床及超聲資料。按不同轉(zhuǎn)歸分為存活組(手術(shù)復(fù)位后隨訪(fǎng)睪丸存活)及失睪組(因缺血、壞死接受患側(cè)睪丸切除術(shù)或手術(shù)復(fù)位后隨訪(fǎng)患側(cè)睪丸萎縮),對(duì)比觀(guān)察兩組聲像圖特征,包括患側(cè)睪丸大小改變、軸向改變、內(nèi)部回聲、血流改變及鞘膜積液。并進(jìn)行統(tǒng)計(jì)學(xué)分析,選取組間差異有統(tǒng)計(jì)學(xué)意義的聲像圖特征,建立Logistic回歸模型預(yù)判患側(cè)睪丸轉(zhuǎn)歸。結(jié)果 45例患兒均為單側(cè)扭轉(zhuǎn),其中左側(cè)27例,右側(cè)18例;最終納入存活組11例,失睪組34例。失睪組34例中,32例患側(cè)睪丸回聲不均勻,2例回聲尚均勻;33例患側(cè)睪丸實(shí)質(zhì)內(nèi)未探及血流信號(hào),1例探及少量血流信號(hào);6例患側(cè)睪丸周邊可見(jiàn)"環(huán)島"征。存活組11例中,9例睪丸實(shí)質(zhì)內(nèi)回聲均勻,2例回聲不均勻;9例患側(cè)睪丸實(shí)質(zhì)內(nèi)血流較健側(cè)減少,2例未探及血流信號(hào)。兩組間內(nèi)部回聲及血流改變差異有統(tǒng)計(jì)學(xué)意義(P均0.05),患側(cè)睪丸大小改變、軸向改變及鞘膜積液差異均無(wú)統(tǒng)計(jì)學(xué)意義(P均≥0.05)。Logistic回歸模型結(jié)果顯示,術(shù)前超聲的陽(yáng)性(失睪)預(yù)測(cè)值為97.10%,陰性(存活)預(yù)測(cè)值為81.80%,預(yù)判睪丸扭轉(zhuǎn)患兒轉(zhuǎn)歸的準(zhǔn)確率為93.30%。結(jié)論術(shù)前超聲對(duì)預(yù)判兒童睪丸扭轉(zhuǎn)的轉(zhuǎn)歸具有較高準(zhǔn)確率,聲像圖中患側(cè)睪丸內(nèi)部回聲及血流改變可作為預(yù)判指標(biāo)。
[Abstract]:Objective to evaluate the value of preoperative ultrasonography in predicting the outcome of testicular torsion in children with testicular torsion. Methods the clinical and ultrasonic data of 45 children with testicular torsion were analyzed retrospectively. According to the different outcomes, the patients were divided into survival group (survival of testis after surgical reduction) and denervated testis group (with ischemic, necrotic or postoperative testicular atrophy). The sonographic features of the two groups were compared and observed. These include changes in the size of the affected testis, axial changes, internal echoes, changes in blood flow, and hydrocele. Statistical analysis was carried out, and the characteristics of sonogram with statistically significant differences were selected, and logistic regression model was established to predict the outcome of the affected testis. Results all 45 cases were unilateral torsion, including 27 cases left and 18 cases right, and 11 cases were included in survival group and 34 cases in denervated testis group. There were 32 cases of testicular heterogeneity and 32 cases of testicular heterogeneity. 33 cases had no blood flow signal in the affected side testicular parenchyma and 6 cases had "ring island" sign around the affected side testis. In the survival group, 9 cases had homogenous echo in testis parenchyma and 2 cases had uneven echo. 9 cases had less blood flow in the affected side than in the normal side, 2 cases had not detected the blood flow signal. There were significant differences in internal echo and blood flow between the two groups (all P 0.05). There was no significant difference in testicular size, axial change and hydrocele between the two groups (P 鈮，
