Results of systematic screening for minor degrees of fetal renal pelvis dilatation in an unselected population

OBJECTIVE: The purpose of this study was to determine the incidence of minor degrees of renal pelvis dilatation that is detected by antenatal ultrasound scanning in an unselected population and its value in the prediction of significant uropathies. STUDY DESIGN: This prospective study was conducted over a 24-month period. Infants with an anteroposterior pelvic diameter of ≥4 mm in the second trimester and/or ≥7 mm but <15 mm in the third trimester were enrolled. RESULTS: Pyelectasis was found in 4.5% of 5643 fetuses (1.5% with significant uropathy). Among the 213 infants whose cases were followed, 132 infants (62%) had renal anomalies, but only 83 infants (39%) had significant uropathies. The ability of the third-trimester renal pelvis dilatation to predict renal abnormalities showed a positive predictive value of 69%. Pyelectasis that was detected only in the second trimester revealed a significant uropathy in 12% of the infants. CONCLUSION: Pyelectasis was found in 4.5% of fetuses. The third-trimester anteroposterior renal pelvis diameter of ≥7 mm was the best ultrasound criterion to predict postnatal uropathies.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Postmortem fetal magnetic resonance imaging: where do we stand?

Abstract Postmortem fetal magnetic resonance imaging (PMFMRI) is increasingly used thanks to its good overall concordance with histology paralleling the rising incidence of parental refusal of autopsy. The technique could become a routine clinical examination but it needs to be standardized and conducted by trained radiologists. Such radiologists should be aware of not only the (congenital and acquired) anomalies that can involve the fetus, but also of the “physiological” postmortem changes. In this article, we intend to focus on the contribution of PMFMRI based on the existing literature and on our own experience, as we presently perform the technique routinely in our clinical practice. Key Points • Concordance rates between PMFMRI and autopsy are high for detecting fetal pathologies. • PMFMRI is more acceptable for parents than traditional autopsy. • PMFMRI is becoming widely used as a part of the postmortem investigations. • A dedicated radiologist needs to learn to interpret correctly a PMFMRI. • PMFMRI can be easily realized in daily clinical practice
