【摘要】 目的为统计胎儿肾盂轻、中度扩张发展为明显肾输尿管病变的发病率,同时评估新生儿超声作为一项筛查手段用于儿童肾输尿管病变的价值进行研究。方法利用超声诊断仪对5475例胎儿检查时发现有肾盂轻、中度扩张者249例(失访41例),剩余208例参与随访,参与随访的所有新生儿出生后满1周及满4周连续2次超声检查,同样在出生后3、6、12及24个月对婴儿肾脏超声检查。结果208例中65例(31%)发现明显的肾输尿管异常,其中3例(5%)需外科手术。另143例(69%)正常或轻微异常。结论胎儿期肾盂轻、中度扩张与儿童肾输尿管病变发病率高有关,同时产前超声检查胎儿肾盂轻、中度扩张及产后超声定期复查是筛查儿童肾输尿管病变的有效方法。更多还原

【Abstract】 Objective To count the incidence rate from fetus light-heavy pyelectasis to children ureter affection,to evaluate ultrasonic diagnosis for the newborn as a filter approach of children ureter affection.Methods Longitudinal study to the 208 cases of 249 (41 missed) samples with fetus light-heavy pyelectasis discovered in 5475 fetuses were examined with ultrasonic equipment.All the new bornes were treated with ultrasonic diagnosis when they were 1 week and 4 week old,and their kidneys in 3,6,12,24 months as well.Results 65 samples of the 208 (31%) were discovered ureter apparently abnormal,among them 3 samples(5%) needed operation.The rest 143(69%) appeared in normal or slight abnormal.Conclusions Light-heavy pyelectasis relates to high incidence rate of children ureter affection.Meanwhile,the antenatal ultrasonic diagnosis of fetus light heavy pyelectasis and postpartum ultrasonic diagnostic re-examination are effective methods in filtering children ureter affection.更多还原
