Abstract:
Objective To observe the ultrasonic manifestations and outcomes of fetal congenital kidney anomalies(CKA)during the second trimester of pregnancy.Methods Data of 223 singleton fetuses with CKA detected with ultrasound during the second trimester of pregnancy were retrospectively analyzed.The ultrasonic manifestations of fetal CKA during the second trimester of pregnancy were observed,and the changes till the third trimester of pregnancy were analyzed.Results Among 223 CKA fetuses,simple renal pelvis separation was detected in 142 fetuses,while simple double renal pelvis malformation in was found in 41,polycystic kidney disease in 11,absent kidneys in 7,simple renal cysts and ectopic kidneys each in 6,smaller kidneys in 4,horseshoe kidneys and unilateral renal pelvis separation complicated with contralateral double renal pelvis malformation each in 2,unilateral renal cyst swelling complicated with contralateral double renal pelvis malformation and unilateral renal double renal pelvis malformation complicated with renal pelvis separation was noticed each in 1 fetus.Abnormalities such as renal pelvis separation,renal pelvis malformation,renal cysts and smaller kidney changed during the third trimester of pregnancy,while polycystic kidney disease,absent kidney,ectopic kidney and horseshoe kidney not significantly changed.Conclusion Fetal CKA had various types being able to change dynamically with the development of pregnancy,among which renal pelvis separation was the most common type.
