title: Outcome of 116 moderate renal pelvis dilatations at prenatal ultrasonography.
abstract: To determine the incidence of urinary tract abnormalities detected in the presence of moderate fetal renal pelvis dilatation, we followed up pre- and postnatally 116 fetuses and children between 1985 and 1995. At prenatal ultrasound, 50 (43%) fetuses showed regressive dilatations, 57 (49%) a stable pattern, and 9 (8%) an evolutive pattern. In the presence of an evolutive dilatation, urinary tract obstruction was present in 8 cases. When a stable pattern was observed, i.e., a patent uropathy was present, surgical correction was performed in 27 of 53 (51%) cases. Regarding the postnatal evolution of 50 prenatal regressive moderate dilatations, we observed in 12 of 50 (24%) vesicoureteric reflux, of which 5 (10%) required surgical correction, and it is concluded that careful and extensive follow-up is mandatory.
