Abstract:
:Twenty-six boys were evaluated and treated for posterior urethral valves. At the time the valves were diagnosed unilateral or bilateral vesicoureteral reflux was present in 58% of the ureters and 69% of the children, while dilatation of the upper urinary tract was present in 88% and 92%, respectively. There was a variety of symptoms and signs, but the most prominent in neonates and infants were vesical urine retention, palpable kidneys and failure to thrive, whereas in the older children voiding dysfunction, incontinence and urinary infection were the most common. Twenty-four out of 26 boys were managed by primary valve ablation and in 62.5% of them this type of treatment was adequate in resolving or sufficiently improving clinical manifestations and roentgenologic findings, requiring no further management. Urinary diversion in the form of vesicostomy and cutaneous ureterostomy was preserved for those patients who did not improve with valve ablation alone. The current aspects concerning posterior urethral valves are also discussed.
