In a 6-year period, 41 young @entity1 with @entity15740 were seen in our department. In 30 cases, the diagnosis had already been suspected by prenatal ultrasonography. A prospective protocol was proposed to the parents which comprised ultrasound evaluation every 3 months until the age of 24 months and renal function assessment at the age of 18 months. In 33 @entity1 , the study was completed as scheduled. At the start of the study, the maximal @entity8 was above the mean length of normal kidneys in all cases where precise measurement was possible. Within 24 months, 7 of the @entity8 disappeared, 20 regressed in size, 1 remained unchanged and only 5 increased in size. Between the age of 0 to 3 months, renal length of the contralateral kidney was within the normal range in 19 @entity1 and above +2SD in 14 cases. At the age of 18 to 24 months, renal length was, with few exceptions, between 0 and +4SD. Inulin clearance was normal in all 33 individuals with a median value of 112 ml/min per 1.73 m2. CONCLUSION: As a rule, @entity8 shrink in the first 2 years of life. In most cases the contralateral kidney maintains a normal renal function as a consequence of progressive @entity1184 .

XXXX : a prospective study on the natural history of the affected and the contralateral kidney.
