What is Stone Analysis? 1
Kidney stones are small, hard masses that form inside the kidneys. They can be problematic when they grow large enough to obstruct urine flow and cause blockage or damage to the ureter. This can cause severe pain.
Stone analysis is a lab test which analyses the chemical composition of the stone.
Why is Stone Analysis suggested? 1
Stone analysis is done when a person passes a kidney stone along with urine. Or, when following symptoms associated with kidney stones show:
- Abdominal pain.
- Nausea and vomiting.
- Bloody urine.
- Frequent urge to urinate.
How is Stone Analysis performed? 1
The doctor provides a container and a straining mesh, through which the patient filters the urine. If stones are found, place them in the container, allow them to dry without adding any tape or tissue, and return them to the doctor for laboratory analysis. Kidney stones might be very small and granular and hence not easily visible.
Alternatively, a urine sample can be provided to the doctor and the laboratory technicians filter the urine for stones. If a kidney stone is too big to pass, surgery may be done to remove it.
What are the parameters measured in Stone Analysis? 12
The results show the chemical composition of the stones and after analysing them, the doctor will recommend further steps and medicines. Common types of kidney stones include Calcium oxalate, Calcium phosphate, Uric Acid, and Struvite.
Stones can rarely also form due to a certain medication the person is on or due to hereditary reasons.
