AIMS
To ascertain the
outcome associated with antenatal renal pelvis dilatation; to recommend
guidelines for postnatal investigation and determine an upper limit of
normal for the anterioposterior dimensions of the fetal renal pelvis.
METHODS
Infants whose
antenatal ultrasound scan showed a fetal renal pelvis of 5 mm or
greater were investigated using postnatal renal tract ultrasound and a
micturating cystogram. Isotope studies were also performed, where appropriate.
RESULTS
Vesicoureteric
reflux (VUR), the most common diagnosis, was evident in 23/104 (22%).
In 14 infants with VUR the postnatal ultrasound scan was normal. There
was no evidence of renal scarring or dysplasia in any of the refluxing
kidneys. Other diagnoses were pelviureteric junction obstruction, renal
dysplasia, and idiopathic dilatation. Antenatal counselling and
parental information facilitated postnatal assessment.
CONCLUSIONS
Infants
with antenatal renal pelvis measurements of 5 mm or greater should be
investigated postnatally, as a significant percentage will have VUR. A
normal postnatal ultrasound scan does not preclude the presence of VUR.
