Enter the maximum diameters in the sagittal, transverse, and anterior-posterior planes into the calculator to determine the bladder volume.

## Bladder Volume Formula

The following formula is used to calculate the bladder volume.

BV = π/6 * D1 * D2 * D3

Variables:

- BV is the bladder volume D1 is the maximum diameter in the sagittal plane D2 is the maximum diameter in the transverse plane D3 is the maximum diameter in the anterior-posterior plane

To calculate the bladder volume, multiply the maximum diameter in the sagittal plane, the maximum diameter in the transverse plane, and the maximum diameter in the anterior-posterior plane. Then multiply the result by π/6.

## What is a Bladder Volume?

Bladder volume refers to the amount of fluid or urine that the urinary bladder can hold. The bladder is a hollow organ that stores urine produced by the kidneys before it is excreted from the body. Its volume can vary depending on several factors, including hydration levels and time since the last urination. On average, a healthy adult bladder can hold up to 500 milliliters of urine comfortably.

## How to Calculate Bladder Volume?

The following steps outline how to calculate the Bladder Volume using the given formula:

- First, determine the maximum diameter in the sagittal plane (D1).
- Next, determine the maximum diameter in the transverse plane (D2).
- Next, determine the maximum diameter in the anterior-posterior plane (D3).
- Next, gather the formula: BV = π/6 * D1 * D2 * D3.
- Finally, calculate the Bladder Volume using the formula.
- After inserting the values of D1, D2, and D3 into the formula and calculating the result, check your answer with the calculator above.

**Example Problem:**

Use the following variables as an example problem to test your knowledge:

Maximum diameter in the sagittal plane (D1) = 5 cm

Maximum diameter in the transverse plane (D2) = 8 cm

Maximum diameter in the anterior-posterior plane (D3) = 10 cm
