The Role of MRI in Evaluation of Fetal Urinary Tract Anomalies with Normal and Abnormal Volume Amniotic Fluid

Abstract

Purpose to evaluate the role of magnetic resonance imaging MRI in evaluation of fetal urinary abnormalities with normal and abnormal volume amniotic fluid after ultrasound examination Methods The prospective study from April to January comprised fetuses with normal volume amniotic fluid patients and abnormal volume amniotic fluid an oligohydramnios patients All fetuses with suspected congenital urinary tract anomalies based on ultrasound underwent MRI examination with T and T MRI The MRI findings were compared to ultrasound micturition urethrocystography MUC computed tomography CT and magnetic resonance imaging MRI findings as a gold standard postpartum imaging and surgical findings Gestational age range was weeks Result In anhydramnios fetuses showed concordant with MRI bilateral multicystic dysplatic kidney MCDK and normal kidney fetus with hypoplasia kidney between ultrasound US and MRI is discordance in oligohydramnios fetuses MRI has additional information autosome recessive polycystic kidney dysplasia ARPKD with fibrocystic liver anterior urethral valve and posterior urethral valve obstruction In normal amniotic fluid MRI gave additional information in patients left hydronephrosis HN prune belly syndrome vesicourinary junction obstruction VUJO bilateral megacystis microcolon intestinal hypoperistaltic syndrome MMIH cloaca Left multicystic dysplastic kidney MCDK L pelvic cyst and horseshoe kidney patients showed concordant with MRI L pelviuretero junction obstruction PUJO Conclusion Fetal MRI can be used as a complementary toll in evaluation of fetal urinary tract anomalies with normal and abnormal volume amniotic fluid cases
