Posterial urethal valves represent the most common post-vesical obstructive malformation. One of the most credited pathological theories considers them an anomalous insertion of mesonephric duct into the cloca or incomplete involution of plicae colliculi. Urinary tract disorders that following posterior urethral valves include hydrouretheronephrosis and functional impairment of the entire urinary tract with consequent renal failure. Treatment of posterior urethral valves consists in their resection. In low-weight patients or in case of poor general condition, temporary external urinary bypass is feasible.
