Overview

Progress in ultrasound examination techniques in the 1980's applied to the uropoetic system in children increased dramatically the efficiency of detection for asymptomatic dilatations of the pyelocaliceal system (PCS). Children with PCS dilatation were examined and in most cases operated on a very timely basis. Monitoring the natural development of the kidney affected by PCS dilatation in the 1990's showed that the functional capacity of the kidney does not decrease even if conservative therapy was applied. Over the last 10 years, diagnostics and treatment of obstructive uropathies in children have improved dramatically and new morphological, functional and laboratory examining methods have been introduced. In spite of that, there is still the issue of timely detection of prognostically significant drainage disorder causing kidney function impairment.

Key words:
infant age, obstructive uropathy, diagnostics, treatment
