[Prenatal differential diagnosis of fetal urinary malformations].
To elaborate prenatal differential-diagnostic criteria of functional and obstructive uropathies, we examined 3287 pregnant women. Obstructive fetal urinary malformations (FUM) were detected in 42 (1.3%) cases. Prenatal ultrasonic assessment of fetal pelvis size depending on filling of the urinary bladder allowed identification of two groups: bladder-independent and bladder-dependent. Basing on our findings, we established prognostically significant differential-diagnostic criteria of a FUM variant. Thus, dependence of the size of caliculopelvic complex and the ureter on filling of the urinary bladder is a basic echographic criterion in functional obstruction. The absence of such dependence is the criterion of organic obstruction.
