    Abstract:
    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. The procedure used as a basic sonographic prenatal screening in 11 children, in 20 clinical suspicion of disease of the urinary pathways, and four neonates were examined on account of an anorectal malformation or abnormality of the external genitalis. The most frequent finding--in 18 children--was hydronephrosis. It was associated with signs of subrenal obstruction (8x), with ren duplex (5x) and with a megaureter (6x). The association of the sonographic finding of dilatation of the intrarenal urinary pathways with absent contrast filling during excretory urography was observed in a child with hydronephrosis and subrenal obstruction and in four children with a multicystic dysplastic kidney. In individual cases the authors detected a valve of the posterior urethra, a sigmoid-vesical fistula, agenesis of the penis and stenosis of the urethra. Eleven neonates had a normal findings of the urinary tract.
