Micturition urodynamic flow studies in children
Insights
Urodynamic assessment helps identify specific voiding patterns in children. This evaluation enables targeted pharmacotherapy, leading to significant symptom remission in most pediatric patients with voiding abnormalities.
Area of Science:
- Pediatric Urology
- Neuro-urology
Background:
- Voiding abnormalities are common in children, potentially indicating neurophysiologic detrusor imbalance.
- Inadequate evaluation can lead to ineffective treatments and surgical interventions.
Purpose of the Study:
- To evaluate children with significant voiding abnormalities using urodynamic techniques.
- To identify specific abnormal voiding patterns and their correlation with symptoms.
Main Methods:
- Urodynamic evaluation was performed on 34 children with severe voiding abnormalities.
- Abnormal voiding patterns were categorized, including hyperactive external sphincter and detrusor dysfunction.
- Patients received pharmacotherapy tailored to their specific diagnosis and symptoms.
Main Results:
- Several abnormal voiding patterns were identified in the pediatric cohort.
- 83.5% of treated patients (24 evaluated) achieved complete symptom remission with targeted pharmacotherapy.
- Remaining patients showed improvement, though occasional symptoms persisted.
Conclusions:
- Urodynamic assessment is crucial for diagnosing complex pediatric voiding dysfunction.
- Tailored pharmacotherapy based on urodynamic findings leads to successful rehabilitation in most children.
- This approach avoids inappropriate medical therapy and ineffective surgical procedures.
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 per cent 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.
