The wide bladder neck and posterior urethra in childhood.

Involvement of anomalies of the bladder and urethra in recurrent urinary tract infections and micturition disorders in children are examined in the light of published evidence and of the authors' own observations. The data of 300 children followed up for a wide bladder neck and posterior urethra at the Nephrology Clinic of Heim Pál Children's Hospital, Budapest, are reviewed. The dilatation in question is regarded as functional, attributable to a congenital neurogenic or myogenic defect. For the management and prevention of the recurrent ascending infections long-term urinary disinfection and meticulous toilet of the external meatus are recommended. The symptoms are expected to subside spontaneously at the age of menarche. The importance of a close nephrologic follow-up is emphasized.
