[Urinary incontinence in neurogenic defects and urogenital anomalies in childhood]

Dysraphic defects may cause neurogenic incontinence in childhood. Constipation and encopresis are often associated. Depending on the involved segment of the spinal cord hyperreflexia or atonia of the detrusor is observed. Similar findings, without anatomic correlation, can be seen in occult-neurogenic voiding dysfunctions. Therapeutic means aim at preservation of kidney function and the best possible continence. If the symptoms cannot be treated by anticholinergic drugs in a low-capacity, hypertonic bladder, augmentation by bowel segments or continent urinary diversion (e.g. Mainz I pouch) is performed. In the last years modalities of clean intermittent self-catheterization in high-capacity, atonic bladders could be enhanced by the development of new atraumatic catheter systems. Urogenital malformation e.g. proximal epispadias and exstrophic bladder can cause incontinence as well. Recently, new therapeutic concepts were introduced. Ectopic ureter (extraurethral incontinence) in girls or posterior urethral valves in boys as a reason for incontinence must not be forgotten.
