【摘要】 目的 :探讨围产儿单纯肾盂积水的预后与结局。方法 :选择 1 86例妊娠 2 8周后B超诊断围产儿一侧或双侧肾盂积水宽度≥ 8mm者为观察对象 ,定期随访至产后 3个月。结果 :发围产儿肾盂积水宽度与膀胱储尿及排空有一定相关性。经 2～ 4周膀胱排空后复查 ,肾盂积水 <8mm者占 62 .3 %。其余围产儿于计划分娩前、临产后、产后 1～ 4周及 3个月继续随访 ,最终恢复正常者占 94.0 9%。结论 :围产儿单纯肾盂积水 ,如不伴有其他泌尿系统异常 ,可能与膀胱储尿有关 ,应看作是一种良性、可逆性、功能性变化更多还原

【Abstract】 Objective:To investigate the pr og nosis and outcome of simple hydronephrosis in perinatal infant.M ethods :186 gravidae with gestational age longer than 28 weeks were ex amined by B-ultrasonography and unilateral or bilateral hydronephrosis with wid th no less than 8mm was found in the fetuses.The following-up observation was c arried out till 3 months after parturition Results:Hydronephrosis width of perinatal infant has ce rtain relevance to urine storage and evacuation of bladder.62.3% cases of hydron ephrosis whose widths were proved to be less than 8mm after evacuation of bladde r through reexamination by B-ultrasonography 2～4 weeks later,The others were r eexamined at the times of antepartum,postpartum,1～4 weeks and 3 months after pa rturition.Eventually,94.0% cases regained to normal.Conclusion: Simple hydronephrosisin perinatal infant without other abnomalit ies in urinary system may be only relevant to urine storage of bladder and be re garded as one benign,reversible and functional change.更多还原
