Bladder outlet obstruction in the neonate.
Seven neonates with severe bladder outlet obstruction causing urine retention and presenting with a large, palpable lower abdominal mass are reported. The obstruction was due in two cases to posterior urethral valves, in one case each to prune belly syndrome, prolapsing ureterocele, urethral diverticle, and in two cases to pelvic neuroblastoma. Diagnosis was based on physical examination and roentgenographic studies. Therapy and prognosis of bladder outlet obstruction in neonates are discussed. Of the seven patients, 3 neonates died, the rest are developing well.
