摘要
目的增加对此病的认知度,提高此病的检测率,延长患儿生命。方法采用仪器为DiasonicGat-way和Sequoia512型彩色多普勒超声诊断仪,探头频率3.5～6MHz。对32例患此病患儿肾脏的大小、形态、结构、病灶的分布、回声以及血供情况进行检测。结果病变均为双侧,患肾有正常的肾轮廓,肾包膜完整。型患儿的肾髓质回声显著增高,高回声的锥体围绕肾窦呈放射状排例,内部为光亮的细点状回声,后方淡声影或无声影。早期肾血供无明显改变,晚期段动脉、叶间动脉可受压变细,弓形动脉以下血供减少。型患儿几乎无肾钙沉着。结论超声对型肾小管性酸中毒有很高的诊断价值,对临床确诊的病例,超声可作为鉴别型或型病变的重要手段之一。
Objective To increase the awareness of type 1 renal acidosis among our colleagues, improve detective rate and prolong life of the patients. Methods Size, morphology, structure of the renal lesions, their disribution, ultrasound echo and their blood supply of the studied subjects were determined with color Doppler ultrasound diagnositic devicen （Diasonic Gatway, sequoia 512 and probe frequency at 3.5-6.0 mega）. Results All the lesions were bilateral, the involved kidneys have normal renal profile with integrated renal capsule. There was significantly increases of renal medulla echo in patient with type Ⅰ renal tubular acidosis, renal pyramid with high echo of ultrasound around the renal sinus dmonstrated radial arrangement and had bright fine granular spotty echo with light echo shadow or without echo shadow behind them. There wasn＇t significant changes of renal blood supply during the early stage, however, the segmental renal arteries and interlobular areries were compressed and became finer,blood supply beyond the arteriae arcuata was decreased. There was almost no renal calcium deposition for type Ⅱ hatients. Conclusions Ultrasound has high diagnostic value in type Ⅰ renal tubular acidosis, and for patients of chinical diagnosis, ultrasound is and improtant tool in the differentiation betwwen type Ⅰ and type Ⅱ renal tubular acidosis.
