“…Although ultrasound is the primary imaging tool in prenatal diagnosis of fetal renal anomalies, the efficacy of ultrasound is decreased in the presence of oligohydramnios, which is a common association with fetal renal anomalies 12–15 . Recent MRI techniques, considered safe for fetuses, can be obtained during breath holding by the mother instead of maternal sedation 16–19 …”

“…Oligohydramnios is commonly associated with fetal urinary tract anomalies and the efficacy of ultrasound as a primary imaging tool in the diagnosis of fetal anomalies is decreased in the presence of oligohydramnios (12)(13)(14)(15). Fifty-four (0.6%) cases of suspected renal anomalies, detected during screening sonography of 8400 pregnant women (0.6%) over two years, were rescanned by MRI to refine the diagnosis of suspected renal anomalies in this study.…”

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.

“…When a fetal ureterocele is diagnosed, close sonographic surveillance should be offered, and when indicated fetal therapy should be performed [5]. All ureteroceles must be prenatally referred to pediatric urology, and ultrasonographic findings should be carefully analyzed before delivery, in order to program postnatal therapy, institute adequate prophylaxis to minimize infectious complications, and to prevent renal damage [11].…”

“…However, prenatal diagnosis has increased with the evolution of prenatal ultrasound assessment. On ultrasound, the ureterocele presents as a cyst inside the bladder [5] and may be suspected in the presence of two separated noncommunicating renal pelvises and a dilated ureter.…”

Ureteroceles are cystic dilations of the intravesical submucosal ureter. Most cases are associated with complete ureteral and renal duplication, and association with ureterohydronephrosis is frequent. The authors describe the 4 cases of fetal ureterocele diagnosed from March 2008 to March 2012. Mean gestational age at diagnosis was 23 weeks (16-34 weeks). One of 4 cases progressed to severe hydronephrosis with megacystis and was referred to a Fetal Medicine Center for fetoscopy and laser ureterocelotomy. The remaining 3 cases did not need fetal therapy. Mean gestational age at delivery was 37 weeks. One case abandoned follow-up; 2 children were submitted to cystoscopic ureterocele incision and the child submitted to fetal therapy needed heminephrectomy due to recurrent urinary tract infections. In those 3 cases renal function was preserved. When a fetal ureterocele is diagnosed, close sonographic surveillance should be offered to monitor the possible urinary tract obstruction and assess the need for prenatal intervention. Fetal diagnosis is important to program the timing of delivery and postnatal care.
