What type of examination is often performed to diagnose kidney stones?

Kidney stones are typically diagnosed using imaging techniques that can effectively visualize the urinary tract and identify any stones present.

An X-ray can be used to detect certain types of kidney stones, particularly those that are radiopaque, such as calcium-based stones. However, not all kidney stones are visible on X-rays, which limits their effectiveness.

A CT scan is a highly sensitive imaging method that can detect even small stones in the kidneys and the urinary tract. It provides detailed cross-sectional images and is particularly useful for diagnosing kidney stones when patients present with renal colic or other symptoms.

Both X-ray and CT scan are valid tools in the diagnosis of kidney stones, as they can each provide valuable information, but a CT scan is generally preferred due to its higher sensitivity and ability to visualize stones that may not show up on an X-ray.

The inclusion of both X-Ray and CT Scan in the answer is appropriate because each modality plays a role in the diagnosis of kidney stones, with CT scans being the most definitive imaging choice. Thus, recognizing that both can be used in the diagnostic process accurately leads to the conclusion that the answer encompasses effective diagnostic techniques.
