Pelvicalyceal dilatation is the most common abnormity identified in ultrasound screening of the urinary tract. Often it is accompanied by dilatation of the ureter too (megaureter). In more than 60% of all cases this finding disappears with age due to maturation of the urinary tract. Otherwise, there are mainly congenital narrowings paticipating in the etiology of dilatation (except for vesicoureteral reflux). It´s usual location is the pelviureteral and vesicoureteral junction and most of them are represented by intraluminal factors. As regards extraluminal causes of obstruction most often we can see aberant vessels crossing ureter in it´s subrenal course. In these cases the aberant vessel is a branch of the aorta and points toward lower pole of the kidney as the main source of its blood suply. At the site of crossing the ureter there may be a difficult outflow of the urine. Our case represents an extraordinary cause of the symptomatic vascular obstruction of the urinary tract - atypical crossing and oppression of the ureter by ovaric vessels.
