Diagnosis and Treatment of Congenital Bladder-Neck Obstruction in Children

Abstract

CONGENITAL bladder-neck obstruction is a common, and potentially serious, pediatric and urologic problem. Sixty-six per cent of the cases of bladder dysfunction reported by Emmett and Simon¹ and 95 per cent of those reported by Burns et al.² showed some type of bladder-neck obstruction. Congenital valves were rarely found. Neurogenic disturbance of some type accounted for the remainder. Unrecognized and untreated, this pathologic abnormality leads to vesical and upper-urinary-tract changes, and ultimately to progressive renal destruction and death.The explanation for the development of this obstructive lesion appears to be a fault in dissolution of mesenchyme at the bladder neck, . . .
