How to Measure Bladder On Ultrasound | Bladder Length, Width, Height & Volume Measurements USG Bladder Measurements: Height (or AP): The measurement from the anterior to the posterior wall of the bladder. Width: Refers to the transverse measurement (from one side of the bladder wall to the opposite side). Length: Refers to the cranio-caudal measurement (from the bladder base to the bladder dome). Calculate bladder volume using the ellipsoid formula: Bladder Volume (ml)=Length (cm)×Width (cm)×Hei

How To Measure The Spleen On Ultrasound | Splenic Length, Width, Thickness & Volume Measurements & Size USG Longitudinal (Length) measurement: With the probe in the longitudinal plane, measure the spleen from its most superior (cranial) to its most inferior (caudal) edge. Width (medio-lateral) measurement: Still in the transverse orientation, measure the spleen from its medial to lateral edge. Transverse (Thickness) measurement: Rotate the probe to a transverse orientation. Measure the spleen fr
