Diagnosis and treatment of antenatal uropathies.
Thirty-five patients with significant fetal hydronephrosis detected on antenatal ultrasound had postnatal investigations which included ultrasound, 99mtechnetium diethylenetriamine pentacetic acid (99mTcDTPA) renal scans and micturating cystourethrograms. Antenatal and postnatal ultrasound were unable to determine reliably the level of obstruction causing the hydronephrosis. The 99mTcDTPA renal scan was useful in determining the necessity and timing of surgery, but could not exclude vesico-ureteric reflux. Seven patients required surgery in the neonatal period and a further seven children had surgery because of deterioration of the scan appearance on follow-up studies performed at 3, 6 and 12 months of age and then at longer time intervals. Twenty patients (almost 60%) have been managed conservatively for a mean of 28 months (range: 12 months-7 years) with no deterioration in renal function.
