Hydronephrosis in the asymptomatic neonate with myelodysplasia

Early diagnosis and intervention in the child with myelodysplasia can effectively improve and preserve renal function in those newborns presenting with abnormalities at birth or who are at risk for deterioration of renal function from infection, vesicoureteral reflux and/or obstruction. During a 1-year period 10 newborns with myelodysplasia were seen. Hydronephrosis was present in 6, reflux in 3 and urinary tract infection in 3. In each newborn adequate decompression of the bladder and complete resolution of the hydronephrosis were achieved. Uroradiographic evaluation was helpful in determining the best mode of therapy for each individual.
