What is NOT true about a urinary bladder calculus?
What is NOT true about a urinary bladder calculus?
Show Hint
Endemic primary bladder stone disease in children is well documented in parts of India.
Updated On: Jul 8, 2026
- Primary stones rare in Indian children
- Transurethral removal is possible
- Most are radio opaque
- KUB clinches the diagnosis
Show Solution
The Correct Option is A
Solution and Explanation
Step 1: Split bladder stones into two types.
Primary stones form in an otherwise normal bladder, often linked to diet in childhood. Secondary stones form because something else is wrong, like blocked outflow, a catheter, or infection.
Step 2: Bring in the India specific fact.
Parts of India, particularly the north, are well known for endemic primary bladder stone disease in young children, tied to diets low in protein and phosphate. This makes primary stones a common, not rare, problem in Indian children. So the claim that they are rare is wrong.
Step 3: Check the remaining claims.
Small to medium bladder stones can usually be broken up and removed through the urethra with an endoscope, so transurethral removal is indeed possible. Most bladder stones have calcium in them, so they show up as radio opaque on X-ray. Because of this, a plain KUB film is often enough to confirm the stone and its location.
Step 4: Conclude.
The one wrong statement is that primary stones are rare in Indian children.
\[ \boxed{\text{Primary stones rare in Indian children, is FALSE}} \]
