We studied the correlation between prenatal diagnosis and postmortem investigations in pregnancies terminated for renal malformations. Over a 5-year period, 77 cases of termination of pregnancy (TOP) for renal malformations were reviewed. Chromosomal anomalies (n = 9) and cases without conventional or virtual autopsy were excluded (n = 15). In 53 cases, prenatal ultrasound diagnosis and conventional autopsy findings were compared. In addition, we compared the accuracy of conventional and virtual autopsy findings in 17 cases. Full agreement was observed in 60.4 % (32/53) of cases. In 26.4 % (14/53) of the cases, the presence of additional malformations did not alter the final diagnosis. However, in 11.3 % (6/53) the final diagnosis was adjusted because of major additional findings. One case showed a total disagreement. Conventional and virtual autopsy were in full agreement in 52.9 % (9/17). Postmortem magnetic resonance imaging (MRI) description and detection of malformations was less complete and failed to correctly diagnose 5/17 cases (29.4 %). In 17.6 % (3/17) of the cases, postmortem MRI revealed malformations not confirmed by conventional autopsy. A high correlation between prenatal ultrasound and postmortem investigations was observed. Conventional autopsy remains the gold standard to reveal additional major and minor malformations, leading to a correct final diagnosis. The added value of virtual necropsy for renal pathology was limited.
