Megacystis-microcolon-intestinal hypoperistalsis syndrome: in utero sonographic appearance and the contribution of vesicocentesis in antenatal diagnosis.

[megacystis-microcolon-intestinal hypoperistalsis syndrome]

The purpose of this report is to describe the in utero sonographic appearance of megacystis-microcolon -intestinal hypoperistalsis syndrome (MMIHS ) and examine the role of vesicocentesis .Two cases of the sonographic appearance of MMIHS were reviewed . We performed vesicocentesis in 2 fetuses with MMIHS and performed vesicoamniotic shunting in 1 of them . The sonographic findings after these procedures were compared with those before puncture .In both cases , ultrasound examination showed a massively enlarged fetal bladder and bilateral hydroureteronephrosis with a normal amount of amniotic fluid . Fetal urinary sodium and chloride concentrations were within normal limits in both cases ; this suggested normal fetal renal function . Generally , it is difficult to detect the dilated fetal bowel in MMIHS , probably because of the disturbance caused by a large bladder . In our cases , however , the ultrasound examination clearly showed fetal bowel dilatation after these procedures ; this made the antenatal diagnosis of MMIHS more definite .The sonographic features after vesicocentesis may be helpful in confirming the antenatal diagnosis of MMIHS .
