Normal bladder wall thickness when empty and when distended are which pair of measurements in millimeters?

Normal bladder wall thickness when empty and when distended are which pair of measurements in millimeters?

• A. 3 / 5
• B. 4 / 2
• C. 5 / 3
• D. 6 / 4

Answer: (C)

Bladder wall thickness varies with how full the bladder is. When the bladder is empty, the wall appears thicker because the detrusor muscle and folds contribute to the measurement. As the bladder fills and stretches, the wall thickens less and the measured thickness decreases. The normal values reflect this: about 5 millimeters when empty and about 3 millimeters when distended. So the correct pair is 5 / 3. In practice, measure perpendicular to the wall at a representative mid-bladder site with the bladder adequately distended, and remember that markedly thicker walls—especially when distended—can indicate pathology such as obstruction or inflammatory processes.
