Micturition urodynamic flow studies in children
Insights
Urodynamic assessment aids in diagnosing pediatric voiding abnormalities, leading to targeted pharmacotherapy. This approach achieved an 83.5% symptom remission rate in children with complex voiding dysfunction.
Area of Science:
- Pediatric Urology
- Neuro-urology
Background:
- Voiding abnormalities are common in children and can stem from neurophysiologic detrusor imbalance.
- Inadequate evaluation may lead to incorrect treatments or failed surgical interventions.
Purpose of the Study:
- To evaluate the effectiveness of urodynamic techniques in diagnosing and managing pediatric voiding abnormalities.
- To identify specific abnormal voiding patterns in children.
Main Methods:
- Urodynamic techniques were used to evaluate 34 children with significant voiding abnormalities.
- Abnormal voiding patterns were categorized, including hyperactive external sphincter and detrusor dysfunction.
- Pharmacotherapy was administered based on diagnosis and presenting symptoms.
Main Results:
- Several abnormal voiding patterns were identified.
- Of 24 treated patients, 83.5% experienced complete symptom remission with pharmacotherapy.
- The remaining patients showed improvement but continued to have occasional symptoms.
Conclusions:
- Urodynamic assessment is crucial for accurate diagnosis of pediatric voiding abnormalities.
- Targeted pharmacotherapy based on urodynamic findings leads to high rates of symptom rehabilitation.
Abstract:
Voiding abnormalities are encountered frequently in pediatric patients. Symptoms of daytime incontinence, frequency and nocturnal enuresis in any combination may indicate underlying neurophysiologic detrusor imbalance. Incomplete evaluation of these symptoms can result in inappropriate medical therapy or even ineffective operations. Within the preceding 7 months 34 children with hard-core voiding abnormalities were evaluated with urodynamic techniques. Several categories of abnormal voiding patterns were identified, including the hyperactive external sphincter, uninhibited pediatric neurogenic bladder, detrusor hyperreflexia secondary to chronic cystitis, hyperactive external sphincter with hypotonic bladder and the hyperactive external sphincter with detrusor irritability. All patients received specific pharmacotherapy based on presenting signs and symptoms, and voiding pattern abnormality. Of the 24 patients who have been treated in this manner and were evaluated 83.5% have had complete remission of symptoms while on therapy, the remainder being improved but still having occasional symptoms. The technique and data demonstrate that children with hard-core voiding abnormalities can achieve rehabilitation with urodynamic assessment.
