Abstract
OBJECTIVES
The purpose of this study is to describe the diagnosis, the care and the prognosis of the fetuses with an antenataly diagnosed megacystis.
PATIENTS AND METHODS
Six year retrospective study about 46 cases of megacystis (26 diagnosed during 1st trimester; 14 during 2nd trimester; 9 during 3rd trimester) referred in the prenatal fetal medicine unit of the Femme-Mère-Enfant hospital in Lyon (France).
RESULTS
The main aetiology is urethral occlusion, particularly for megacystis discovered during the 1st and the 2nd trimesters. Twenty-two terminations of pregnancy were performed (47.8%) and 6 pregnancies arrested spontaneously (13%). Eighteen children were born alive, but 2 died in neonatal period. Finally, 16 children survived (34.8%). Chromosomal abnormalities are frequent (22%).
DISCUSSION AND CONCLUSION
Antenatal discovery of a megacystis is a complex situation, and often of poor fetal prognosis. It requires a multidisciplinary approach to allow the concerned couple to be determined on the best care of this pregnancy.
