[Biofeedback for urinary bladder dysfunctions in childhood. Indications, practice and the results of therapy].
In children, abnormal behavior during micturition, i.e. detrusor/sphincter dyscoordination, causes persistent voiding problems, urinary incontinence and/or recurrent urinary tract infections in up to 15% of cases. Contractions of the external urethral sphincter during micturition lead to functional subvesical obstruction. Nowadays, biofeedback training is the most suitable therapy. Biofeedback training for children is based on the assumption that relaxation and contraction of the urinary external sphincter is a habitual phenomenon and can be restored. With specially developed, computer-assisted biofeedback programs, sphincter contraction and relaxation can be transformed into acoustic or visual signals. Acoustic or optical feedback indicates relaxation and contraction control to the patient. The residual urine volume should subsequently be assessed. The results should be reviewed after each micturition. Poor compliance sometimes makes biofeedback training impossible. Further biofeedback training at home is a reasonable suggestion. Good results-a response rate of up to 90%-demonstrates that biofeedback training is successful in the treatment of detrusor-sphincter dyscoordination. After effective therapy, associated urinary tract infections and vesicoureterorenal reflux may disappear.
