Final answer:
The composition of a urolith can only be accurately identified by sending it to a reference laboratory for detailed analysis, including possible X-ray analysis and microscopy.
Step-by-step explanation:
The only way to correctly identify the composition of a urolith, which is a kidney stone, is to send it to a reference laboratory. While other methods, such as assessing size, shape, and appearance, can provide some information, they are not definitive for determining the exact mineral composition of a urolith.
Techniques such as X-ray analysis and in some cases, advanced microscopy may be used by the laboratory to analyze and identify the components of the urolith accurately. Such detailed analysis is necessary because the treatment and prevention strategies for kidney stones can vary depending on their composition.
