1. What is a Bladder Volume Calculator Pediatric?

Definition: This calculator estimates bladder volume in children based on ultrasound measurements of length, width, and height.

Purpose: It helps medical professionals assess bladder function and capacity in pediatric patients.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Volume of bladder (cm³)
• \( L \) — Length measurement (cm)
• \( W \) — Width measurement (cm)
• \( H \) — Height measurement (cm)

Explanation: The formula calculates bladder volume assuming an ellipsoid shape, adjusted for pediatric norms.

3. Importance of Bladder Volume Calculation

Details: Accurate bladder volume assessment helps diagnose urinary retention, monitor bladder function, and guide treatment decisions in children.

4. Using the Calculator

Tips: Enter the length, width, and height measurements obtained from ultrasound in centimeters. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is this formula specifically for pediatric patients?
A: The formula accounts for the smaller size and different proportions of children's bladders compared to adults.

Q2: How accurate is this calculation?
A: It provides a good estimate (within 10-15% of actual volume) when proper ultrasound measurements are taken.

Q3: What's the normal bladder capacity for children?
A: Normal capacity varies by age: approximately (Age in years + 1) × 30 mL.

Q4: When would this calculation be used?
A: For evaluating urinary retention, incontinence, or before catheterization in pediatric patients.

Q5: Can this be used for newborns?
A: Yes, but the formula may slightly overestimate volume in very small infants.
