1. What is a Prostate Volume Calculator Ultrasound?

Definition: This calculator estimates prostate volume using ultrasound measurements based on the ellipsoid formula.

Purpose: It helps medical professionals assess prostate size for diagnostic purposes and treatment planning.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V = \frac{\pi}{6} \times L \times W \times H \]

Where:

\( V \) — Volume of prostate (cm³)
\( L \) — Length (cm)
\( W \) — Width (cm)
\( H \) — Height (cm)

Explanation: The formula calculates the volume of an ellipsoid, which approximates the shape of the prostate gland.

3. Importance of Prostate Volume Calculation

Details: Accurate prostate volume measurement is crucial for diagnosing benign prostatic hyperplasia (BPH), assessing cancer risk, and planning surgical interventions.

4. Using the Calculator

Tips: Enter the three orthogonal dimensions (length, width, height) measured via transrectal ultrasound. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why use the ellipsoid formula?
A: The prostate gland roughly resembles an ellipsoid shape, making this formula a practical approximation for clinical use.

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 a normal prostate volume?
A: Typically 20-30 cm³ in young men, often increasing with age (may reach 40-60 cm³ in older men).

Q4: Can this calculator estimate prostate weight?
A: Yes, multiply volume by 1.05 g/cm³ (average tissue density) to estimate weight in grams.

Q5: When is prostate volume measurement most important?
A: For evaluating BPH symptoms, planning surgical procedures, and assessing PSA density (PSA divided by volume).
