Despite high resolution of instruments, pelvic dilatation alone is usually taken into account during obstetric ultrasonography (US) of fetal urinary tract. In January 1990, a perspective longitudinal study, considering the measurements of pelvis dilatation (PD), parenchymal thickness (PT), kidney length and ureter, was begun. 132 fetal renal units (99 fetuses) were consecutively observed at 30 to 38 weeks of gestation. The relationship between groups of outcome (normalized, affected, operated kidneys) and antenatal parameters has shown that 16% of PD 20 mm were normalized during a 2-year follow-up. On the contrary, the parameter PT was quite reliable. Pelvic size alone is not sufficient to predict the outcome, and other parameters are needed.
