Pediatric Voiding Dysfunction

As pelvic rehabilitation providers, it may be safe to assume a lot of us are treating adults with bladder and bowel dysfunction. Often we get questions from these patients about treatment for children with voiding dysfunction. How comfortable are we treating children for these problems and what would we do? Pediatric voiding dysfunction and bowel problems are common and can have significant consequences to quality of life for the child and the family, as well as negative health consequences to the lower urinary tract if left untreated. No clear gold standard of treatment for pediatric voiding dysfunction has been established and treatments range from behavioral therapy to medication and surgery.

A randomized controlled trial in 2013 that was published in European Journal of Pediatrics, explores treatment options for pediatric voiding dysfunction. Pediatric voiding dysfunction is defined as involuntary and intermittent contraction or failure to relax the urethral striated sphincter during voluntary voiding. The dysfunctional voiding can present with variable symptoms including urinary urgency, urinary frequency, incontinence, urinary tract infections, and abnormal flow of urine from bladder back up the ureters (vesicoureteral reflux).

The 2013 study compared 60 children over one year who were diagnosed with dysfunctional voiding into two treatment groups. One group received behavioral urotherapy combined with PFM (pelvic floor muscle) exercises while the other group received just behavioral urotherapy. The behavioral urotherapy consisted of hydration, scheduled voiding, toilet training, and high fiber diet. Voiding pattern, EMG (electromyography) activity during voids, urinary urgency, daytime wetting, and PVR (post-void residue) were assessed at the beginning and end of the one year study with parents completing a voiding and bowel habit chart as well as uroflowmetry with pelvic floor muscle sEMG (surface electromyography) was administered to the child for voiding metrics.

All parents and children in both groups received education about urinary and gastrointestinal tract function as well as healthy bladder habits, effects of high fiber diet, scheduled voiding, and normal mechanics of toilet training. For the group that completed PFM exercises and education, they participated in 12 sessions (2x/week for 30 minutes) to learn the PFM exercises under the guidance of a single physical therapist. There was bimonthly follow up for both groups throughout the 12 months to ensure retention and application of the behavioral urotherapy.

The goal of the PFM exercises for the children was too restore the normal function of the PFM’s and their coordination with abdominal muscles. The exercises that the children completed, included exercises with and without a swiss ball. The exercises without a swiss ball included breathing with the diaphragm, Transversus Abdominus muscle isolation, hip adductor squeeze (isolation), bridging with PFM relaxation, and cat/camel to improve lumbopelvic coordination. Swiss ball exercises included seated PFM contraction and relaxation exercise with a seated lift and relax, supine bridge with roll out on the ball with PFM contraction, and supine swiss ball lift with the legs and pelvic contraction. (Pictures and more details about how the exercises were carried out in the article itself.)

The conclusion of the study was that the functional PFM exercises with swiss ball combined with behavioral urotherapy reduced the frequency of urinary incontinence, PVR (post void residue), and the severity of constipation in children with voiding dysfunction. The children in the combined group showed improvements with voiding pattern, reduced EMG activity during voids, reduced urgency, reduced daytime wetting, and improvements with more complete emptying with voids (reduced PVR).

The Functional PFM exercises are easy to teach and easy for children to complete. They are a safe, inexpensive, and effective treatment option for children with dysfunctional voiding. PFM exercises combined with behavioral urotherapy seems to be a logical treatment option for treating pediatric voiding dysfunction.
