Abstract:
Purpose: Bladder / bowel dysfunction is a relatively frequent condition of various etiologies in children. The
aim of the study was to evaluate the informative value of transperineal sonography of the pelvic floor muscles
in determining the indications and evaluating the effectiveness of biofeedback therapy in children with bladder
/ bowel dysfunction.
Material and methods. From 2010 to 2016, 128 (69 girls and 59 boys) aged 5-14 years (mean 8.9 ± 3.1)
with bladder / bowel nonneurogenic dysfunction were included. 56 (43,8%) of children complained of difficulty
during urination, incomplete emptying of the bladder and 8 (6,2%) - incontinence, in 64 (50%) children had
chronic constipation with incontinence. All children before and after treatment
were examined with Disfunctional Voiding Symptom Score, a Bristol stool scale, uroflowmetry with determination of residual urine and EMG of pelvic floor muscles and with transperineal ultrasonography.
Results. The results of a comprehensive study showed decrease in the flow rate on average by 37 ± 12%,
the volume of residual urine did not exceed 30%, and an increase in activity of the pelvic floor muscles was
noted on the EMG curve. All patients were diagnosed with a paradoxical movement of the pelvic floor muscles.
It was an indication for therapy with biological feedback.
Patiens were underwent biofeedback therapy clinical improvement was noted in all cases. Improvement
in the form of uroflowmetric curve, the amount of residual urine did not exceed the permissible values in 38
patients, and in 18 the amount of residual urine decreased to 15-17%.The stress urinary incontinence in all children was absent. In 6 children the faecal incontinence disappearance There was an increase in frequency stools
and reduction of episodes of the faecal incontinence in other. In control transperineal ultrasound, complete
disappearance of paradoxical movement of the pelvic floor muscles was noted in 45(34%) cases, and positive
dynamics - in other patients.
Conclusions. The method of biofeedback therapy is effective in bladder/bowel nonneurogenic dysfunction.
For detection and monitoring patients with this pathology can be recommended safe and simple methods -
dynamic transperineal ultrasonography.
