Abstract
Modern imaging methods increase frequency of detection of congenital urinary tract anomalies. Routine ultrasound investigation in second trimester of pregnancy enables prenatal diagnosis of urinary tract dilatation.
These defects can cause tubular damage and decreased nephron number and result in chronic renal failure in severe cases of bilateral dilatation. Contemporary medicine offers variety of treatment options of these anomalies from conservative to surgical approach with preference for methods of conservative treatment and miniinvasive surgery (endoscopy,laparoscopic operations).
