Insights
Most children with lower urinary tract dysfunction (LUTD) experience urinary tract infections (UTI) and daily incontinence. Micturition diary and clinical history lack accuracy in diagnosing LUTD symptoms like urgency or coordination issues.
Area of Science:
- Pediatric Urology
- Urodynamics
- Clinical Pediatrics
Background:
- Lower urinary tract dysfunction (LUTD) is a common condition in children.
- Understanding the clinical presentation and diagnostic challenges of LUTD is crucial for effective management.
Purpose of the Study:
- To correlate the clinical presentation of pediatric LUTD with objective urodynamic findings.
- To evaluate the diagnostic utility of patient history and micturition diaries in identifying LUTD.
Main Methods:
- Prospective assessment of 44 children with LUTD using questionnaires.
- Comparison of clinical data with objective measures including micturition diaries and uroflowmetry with electromyography.
Main Results:
- A history of urinary tract infection (UTI) was present in 70.5% of cases, often with fever.
- Urinary urgency was universal; daily incontinence affected 75% and nocturnal enuresis 52.3%.
- Uroflowmetry revealed lack of coordination during micturition in 31.8% of patients, with discrepancies between reported and recorded voiding frequencies.
Conclusions:
- Previous UTI is common in children with LUTD.
- Micturition diaries and clinical history show limitations in accurately capturing symptoms like urgency and infrequent voiding.
- Clinical history alone lacks sufficient sensitivity and specificity for diagnosing detrusor-sphincter dyssynergia in pediatric LUTD.
Objectives:
To assess the clinical presentation of children with lower urinary tract dysfunction (LUTD) relating to objective examination data.
Materials And Methods:
Forty-four children (36 girls and 8 boys with mean age of 6.8 years) with LUTD were prospectively assessed through a specific questionnaire that analyzed clinical presentation of those patients. These data were then compared to objective data, such as micturition diary and uroflowmetry with electromyography.
Results:
A urinary tract infection (UTI) antecedent was observed in 31 cases (70.5%), and of those, 24 cases of UTI were accompanied by fever. All children presented micturition urgency. Daily urinary incontinence was observed in 33 cases (75%) and nocturnal enuresis in 23 (52.3%). As for micturition frequency, 15 (34.1%) had normal frequency 19 (43.2%) presented more than 10 daily micturition episodes and 10 (22.7%) thought they urinated less than 5 times a day. In the uroflowmetry and electromyography examination, 14 (31.8%) experienced lack of coordination during micturition. Of 10 children with infrequent micturition, 5 confirmed this in their micturition diaries and 2 listed more than 5 micturition episodes per day in the diary. Of 19 patients presenting polaciuria, only 5 confirmed this in their micturition diaries, while 7 had less than 10 micturition episodes per day.
Conclusion:
Most children with LUTD presented a previous UTI, and daily incontinence was verified in around 75% of the patients. Complaints of polaciuria or infrequent micturition are not noted completely in the micturition diaries and there is no parameter in the clinical history that offers good sensitivity or specificity for the diagnosis of lack of perineal coordination.
