[Outpatient echographic follow-up of patients with Fraley's syndrome]

The follow-up of the degree and evolution of the upper hydrocalicosis and of the parenchymatous changes in patients with Fraley's syndrome is very important. All authors agree that these patients should be followed up periodically. 20 patients with Fraley's syndrome were followed up and the authors conclude that the echographic examination is a very reliable method for prophylactic medical examinations since it is informative, harmless and economically advantageous.
