Normal bladder AP wall thickness when fully distended is less than what?

Normal bladder AP wall thickness when fully distended is less than what?

• A. <2mm
• B. <3mm
• C. <4mm
• D. <6mm

Answer: (B)

When the bladder is fully distended, the wall stretches and becomes thinner. The normal AP wall thickness in a well-distended bladder is less than 3 mm. This threshold helps distinguish a normal bladder from conditions that thickening the wall, such as cystitis, tumors, or obstruction. Keep in mind that a non-distended or poorly distended bladder can appear thicker (often up to about 5–6 mm) due to folds and edema, which is why ensuring full distension is important when assessing wall thickness. For measurement, use a single cross-sectional view and measure from mucosa to mucosa at the thickest part, avoiding surrounding tissue.
