title: The obstructed bladder syndrome in the neonate.
abstract: Eleven neonates with bladder obstruction, causing retention of urine, and a large, palpable lower abdominal mass were treated at the Yale-New Haven Hospital during a five year period. Intrinsic and extrinsic lesions, including urethral atresia, posterior urethral valves, ectopic ureteroceles, hydrocolpos and a neuroblastoma of the pelvis, were diagnosed by cystography, vaginography, pyelography and barium enema examination or a combination of these reoentgenographic methods. The multiplicity of underlying lesions make the obstructed bladder syndrome in the neonate a unique condition.
