What is the diagnosis based on the following X-ray?
Ans. C. Bladder stone
- Multiple bladder calculi. Four oval radiopaque bladder stones are visible centrally in the pelvis. Most bladder calculi are round or oval, but they may also be amorphous, laminated, or even speculated.
- Calculi may form as a result of infection (especially with proteus in an abnormally functioning bladder) when the calculi are magnesium ammonium phosphate and apatite.
- Calculi are often asymptomatic but may present with haematuria, suprapubic pain, disruption of the urine stream or recurrent infection.
- They may appear as radiopaque spiculated (jackstone), laminated or amorphous lesions.
- As with upper tract calculi, on contrast investigations, they are usually seen as filling defects, as they are mostly less radiopaque than contrast.
- Ultrasound reliably demonstrates them as highly echogenic mobile foci, especially when the bladder is full.
