Diagnosis of detrusor hyperactivity in children with neurogenic bladder.

Detrusor hyperactivity and its reproducibility was investigated in 22 patients with myelodysplasia and neurogenic bladder. The examinations were performed with microtransducers in the bladder, proximal urethra and rectum. Hyperactivity was found in 15 children all belonging to low lumbar and sacral neurological lesion groups. Patients without hyperactivity mostly had their levels of lesion higher in the spinal cord. In 6 children without neurologic disease no hyperactivity was found.
