title: Congenital ureteral valves: report of 2 patients, including one with a solitary kidney and associated hypertension.
abstract: We report 2 cases of congenital ureteral valves treated successfully by excision of the involved segment and ureteroureterostomy. Hypertension in 1 patient and recurrent urinary tract infection in the other prompted initial evaluation. In the hypertensive patient renin collections from the vena cava and the renal vein of the solitary kidney were normal. Nevertheless, relief of obstruction has resolved the hypertension for 3 years. We review the literature regarding ureteral valves and discuss the mechanism by which unilateral hydronephrosis probably produces hypertension.
