“…However, postnatal kidney function is difficult to predict based on ultrasound studies, especially the long-term outcome [4,5]. Magnetic resonance imaging scans can provide additional information on fetal urinary tract abnormalities in some cases, but these have not been evaluated as a modality to predict postnatal outcome [6,7]. Therefore, some studies have focused on the assessment of biochemical markers in fetal urine or blood to predict the postnatal outcome of kidney function.…”

The presence of renal oligohydramnios (ROH) in a fetus has been associated in the past with a poor prognosis for survival, although recent studies have shown that survival has improved considerably due to the advances in neonatology and pediatric nephrology. In an article recently published in Pediatric Nephrology, evaluation of a large series by Mehler and colleagues confirms the improved prognosis, showing a survival rate of 32 of 38 (84%). In addition, only 12 of 35 (34%) neonates required renal replacement therapy. In five of these 12 children the dialysis could be terminated after the neonatal period. This study has important implications on the decision-making process and counseling of families. While 37% of families of the study opted for termination of pregnancies, palliative care was chosen by 8% of the families, representing an important option when a decision cannot be made rapidly by affected families. A multidisciplinary approach is not only necessary in the active treatment of neonates with a history of ROH but also in antenatal counseling. In this regard future efforts should establish consensus on an ethical framework for the decision-making process in ROH.

“…Gupta et al conducted a prospective study in which they performed MRI studies of fetuses with suspected renal abnormalities based on sonographic examination. These authors reported that MRI results confirmed ultrasound findings in 70.4 % of fetuses and supplied additional information in 25.9 % [20]. Especially in fetuses with ROH, MRI may therefore provide more specific information that can be important for postnatal management and prognosis.…”

It was reported that unilateral hydronephrosis is the most common fetal renal anomaly and normal amniotic fluid volume is the usual finding, but oligohydramnios is associated with bilateral renal anomalies (18,19).…”

“…Fetal MRI was introduced in 1983, but the ultra-fast MRI sequences allows excellent detection of fetal anatomy without the need for maternal sedation (7)(8)(9). MRI as a complementary modality is more popular in such a setting because it enables the fetus to be viewed in multiple planes, irrespective of fetal lie and has excellent resolution (10,11). This study was designed to detect the role of magnetic resonance imaging in refining the diagnosis of suspected fetal renal anomalies detected during screening sonography.…”

Objective: This prospective study was designed to detect the role of magnetic resonance imaging (MRI) in refining the diagnosis of suspected fetal renal anomalies detected during screening sonography.Material and Methods: 54 pregnant women, with suspected fetal renal anomalies detected during routine ultrasound screening, were rescanned by MRI to refine the diagnosis of the suspected renal anomalies. The pregnancy outcome was examined externally and by postnatal ultrasonography.Results: Fifty-four cases of suspected renal anomalies detected during screening sonography of 8400 pregnant women (0.6%), were rescanned by MRI in this study. The MRI gave a similar diagnosis to postnatal ultrasound in 46 cases (16 cases of hydronephrosis, 14 cases of Polycystic Kidney Disease (PCKD), 9 cases of Multicystic Kidney Disease (MCKD), 2 cases of Renal Agensis (RA), 3 cases of single renal cyst and 2 cases of megacystis+hydroureter), while it gave a different diagnosis (false positive) in 6 cases (4 cases of hydronephrosis diagnosed by MRI confirmed to be PCKD by postnatal ultrasound, also, 1 case of MCKD diagnosed by MRI confirmed to be hydronephrosis by postnatal ultrasound and 1 case of RA diagnosed by MRI confirmed to be normal by postnatal ultrasound). The prenatal ultrasound gave a similar diagnosis to postnatal ultrasound in 43 cases (14 cases of hydronephrosis, 13 case of PCKD, 9 cases of MCKD, 2 cases of RA, 3 cases of single renal cyst and 2 case of megacystis+hydroureter), while it gave a different diagnosis (false positive) in 9 cases; 4 cases of hydronephrosis diagnosed by prenatal sonography confirmed to be PCKD by postnatal ultrasound, one case of PCKD+one case of MCKD, and one case of megacystis+hydroureter confirmed to be hydronephrosis by postnatal ultrasound, while one case of MCKD diagnosed by prenatal sonography was confirmed to be PCKD by postnatal ultrasound and one case of RA diagnosed by prenatal ultrasound was confirmed to be normal by postnatal ultrasound. Conclusion:The MRI can be used as a complementary adjunctive modality with excellent tissue contrast, especially in equivocal cases or inconclusive sonographic findings.

The role of magnetic resonance imaging in fetal renal anomalies

Abstract: Ultrasound is the imaging modality of choice for the diagnosis of fetal renal anomalies; fetal MRI is a useful adjunct, especially when ultrasound is inconclusive owing to oligohydramnios.
