- W3031045464 abstract "目的探讨新生儿肾积水盂管交界处狭窄段的病理变化、手术及保守治疗的指征. 方法总结10例新生儿肾积水的治疗.10例均行B超、IVU或CTU、ECT检查.7例8个肾因肾盂及肾盏明显扩张、肾功能中至重度损害,行切除盂管狭窄段、肾盂成形及肾盂输尿管吻合手术治疗,切除的盂管狭窄段行病理及超微结构观察;1例由输尿管末端囊肿引起的肾积水,经膀胱行输尿管囊肿开窗术;另3例肾积水较轻,肾功能正常或轻度受损,未手术只行长期观察随访.结果 7例手术患儿术后恢复顺利,术后随访3个月～3年,肾积水减轻,肾功能明显改善.病理检查,见管腔内上皮细胞无明显变化,管壁平滑肌细胞排列紊乱、退化、变性,细胞间隙增大,管壁内有大量胶原纤维增生致管腔狭窄.3例观察随访的患儿无明显变化.结论①对肾盂轻度扩张(肾盂直径<12 mm),肾功能正常或接近正常(相对肾功能大于40% )的患儿,可随访观察;②对肾盂扩张,积水程度严重(中～重度),肾功能受损;或在观察治疗过程中,肾功能进行性减退的患儿,应行手术治疗,这类患儿多已存在不可逆的病理组织变化." @default.
