Children as well as adults have been visited my Urology office. There’s one symptom that very commonly complaint in pediatric patients, and that is “Child urinary frequency”. The urinary frequency normally concomitant with urinary urgency, in medical professional categorized them as a syndrome called Overactive bladder syndrome (OAB). This syndrome OAB has been reported perhaps 23% begun at age 5 years old and it will drop down to 12% while at 13 years old with a negatively impact on self-esteem along with the impairs of their development.

Child urinary frequency

• Daytime – Small amount of voiding volume which is more than 8 times a day.
• Nighttime – One or more nighttime urinating

While we have confirmed the diagnosis; with a full history taking; physical examination and laboratory investigation, then we will discuss about the treatment plan that would be divided into conservative treatment and oral medication.

1. Conservative treatment – education, scheduled voiding every 2-3 hours, proper voiding technique, minimize fluid before bedtime, avoid caffeine/chocolate/citrus/carbonated drinks, treat constipation.
2. Oral medication – Oxybutynin is the only US FDA-approved agent for OAB in children. Common side effects: dry mouth, dry eyes, dry skin, constipation.

There are varieties of alternative off-label oral tablets or even intravesical botulinum toxin injection in case a severe Child urinary frequency is encountered. But the important part of the treatment is patient and family counseling and setting a realistic goal of treatment.

If you have any questions on Child urinary frequency, you can discuss with your trusted Urologist or it would be my pleasure if you text me. See you around!

Frequently Asked Questions

Q1: What is considered abnormal urinary frequency in children?

Urinary frequency in children is considered abnormal when a child urinates more than 8 times during the daytime in small volumes, or experiences one or more episodes of nighttime urination (nocturia). When urinary frequency is accompanied by a sudden strong urge to urinate, this is classified as Overactive Bladder syndrome (OAB), which affects approximately 23% of children at age 5.

Q2: What causes overactive bladder (OAB) in children?

The causes of OAB in children include bladder immaturity, dietary triggers such as caffeine, chocolate, citrus, and carbonated drinks, constipation (which puts pressure on the bladder), urinary tract infections, and behavioral or psychological factors. In many cases, no single identifiable cause is found and the condition improves with age and proper management.

Q3: How is urinary frequency in children treated?

Treatment begins with conservative measures including scheduled voiding every 2-3 hours, avoiding bladder irritants (caffeine, citrus, carbonated drinks), minimizing fluid intake before bedtime, teaching proper voiding technique, and managing constipation. When conservative treatment is insufficient, the only US FDA-approved oral medication for OAB in children is Oxybutynin, though it can cause dry mouth, dry eyes, and constipation as side effects.

Q4: Will my child outgrow urinary frequency?

Many children do improve with age. The prevalence of OAB drops from approximately 23% at age 5 to around 12% by age 13 as bladder capacity and control mature. However, untreated OAB can negatively impact a child’s self-esteem and development, so early appropriate management is important rather than simply waiting for spontaneous resolution.

Q5: When should I bring my child to see a urologist for urinary frequency?

You should consult a pediatric urologist if your child’s urinary frequency is affecting their daily activities, sleep, or school performance; if there are signs of urinary tract infection such as pain or burning during urination; if the child is wetting themselves during the day despite being toilet trained; or if conservative measures have not improved the symptoms after several weeks of consistent effort.
