"The normal functional volume of the adult healthy bladder is 300-400 mL 7. Throughout childhood, the normal functional volume progressively increases, and can be estimated by ((years of age + 2) × 30 mL) 7. In disease states, such as chronic neurogenic bladder, the volume of the bladder can be significantly increased (e.g. 11 L 8)."
"Bladder volume can be calculated on cross-sectional imaging using the standard volume of an ellipsoid (π/6 x width x height x length), although using a correction of 0.7 (rather than π/6 = ~0.524) has been shown to be closer to voided/catheterised volumes 9. The discrepancy between calculated bladder volumes (using these formulas or automated three-dimensional (3D) scanning ultrasound devices) increases the less ellipsoid the bladder shape is; this is particularly marked when estimating post void residual urine volumes 9,10."
