摘　　要：目的探讨中孕期胎儿单纯性肾窦分离的程度与预后的关系。方法对88例超声检查发现的中孕期单纯性肾窦分离胎儿进行跟踪检查,并与晚孕期、出生后随访结果或尸检病理结果进行对比研究。结果 88例胎儿在中孕期有144只肾脏表现为肾窦分离,间距为(4.21±2.66)mm,晚孕期有74只肾脏表现为肾窦分离,间距为(3.68±4.50)mm;中孕期与晚孕期肾窦分离宽度比较差异无统计学意义(P>0.05);中孕期肾窦分离<10mm的肾脏中91.2%(124/136)自然恢复正常,≥10mm的仅有2/8恢复正常(P<0.01)。结论中孕期单纯性肾窦分离大多为一过性,肾盂扩张较轻者多可恢复正常,但需要进行随访观察;少数胎儿单纯性肾窦分离虽然较轻但未能恢复正常,应进行超声随访。Objective To explore the relationship between the degree of simple hydronephrosis during second trimester and its prognosis. Methods Eighty - eight fetuses with simple hydronephrosis confirmed by uhrasonography were examined, the results were compared with those of the third trimester, postnatal outcome or pathologic findings. Results One hundred and forty -four renal pelvis dilation were found in 88 fetuses in second trimester, the distance was （4.21± 2.66） ram, and 74 renal pelvis dilation were found in third trimester, the distance was （3.68 ± 4.50 ） mm, there was no significant difference between the second trimester and third trimester （P 〉 0. 05 ）. 91.2% （124/136） of renal pelvis dilation less than 10 mm in the second trimester baeame normal, and 2/8 of renal pelvis dilation more than 10 mm became normal （ P 〈 0.01 ）. Conclusion Most simple hydronephrosis in second trimester is transient, most patients with mild pevieetasis can return to normal without any intervention, and simple hydronephrosis in fetus needs ultrasonic observation and follow- up.
