title: [Anterior urethral valves].
abstract: The valves of the anterior urethra are a rare congenital malformation, but it can cause a significant deterioration of the uppermost urinary system due to their obstructive patterns. It's placed fundamentally in the peno-scrotal union or in the bulbous urethra. They can associate to the diverticula of the anterior urethra. The clinical manifestations can be varied, depending upon the age of the child and the degree of obstruction that provoque. The treatment is always surgical, although in some occasions they suffice the endoscopic resection. We present the 12 cases controlled in our Center, with known ages between 1 month and 7 years, that began with tumefaction urethral at micturition in 7 cases, urinary infection in 6 and sepsis in 2. All of them required open surgery, after the failure of endoscopic resection in one of them. The results have been favorable in 9 cases regarding to the repercussions in the renal function. Two patients had a need of nephrectomy and one had to be subjected to a renal transplantation. The jet at micturition after surgery is good in 10 cases. In one, there persists a subtle jet, although without clinical repercussions, and in one patient there appeared a slight dilation in the posterior urethra.
