[Diagnostic imaging methods in neonates with diseases of the urinary tract].

The actually used examination algorithm of imaging methods was checked in 35 neonates examined in the course of two years (1991 and 1992) on account of suspected diseases of the urinary pathways. It involved sonographic examination of 28 children, voiding cystourethrography (34x) and intravenous urography (18x). Ascendent pyelography and irrigography were performed three times, one neonate was examined by computed tomography.
