Summary
Jackstone calculi, urinary tract stones resembling toy jacks, were incidentally detected using abdominal sonography. This is the first reported case of jackstone calculus identification via ultrasound in a human patient.
Area of Science:
- Urology
- Radiology
- Medical Imaging
Background:
- Jackstone calculi are urinary tract stones primarily composed of calcium oxalate dihydrate.
- Their characteristic appearance is well-documented on radiography and computed tomography (CT) in humans and animals.
- Previous literature lacks reports of jackstone calculi identified through sonographic examination in humans.
Observation:
- A large jackstone calculus was incidentally discovered during abdominal sonography.
- The patient was a 75-year-old male.
Findings:
- This case represents the first documented instance of a jackstone calculus identified using diagnostic ultrasound in a human.
- Sonography can be an effective tool for detecting these specific urinary tract stones.
Implications:
- Highlights the utility of sonography in diagnosing urinary tract calculi, including rare presentations like jackstone calculi.
- May prompt consideration of sonography for identifying jackstone calculi in clinical practice.
- Contributes to the imaging literature on jackstone calculi across different modalities.
