TL;DR: Kidney stones are primarily diagnosed through a combination of physical examination, clinical history, and diagnostic imaging, most commonly a non-contrast CT scan of the abdomen and pelvis. While passing a small stone may be managed conservatively, imaging is essential to confirm the presence, size, and location of the stone to determine the safest treatment plan. How is a diagnosis of kidney stones confirmed? The diagnostic process for kidney stones typically begins with a review of your symptoms, such as sudden, severe flank pain or hematuria (blood in the urine).

How is a diagnosis of kidney stones confirmed?
The diagnostic process for kidney stones typically begins with a review of your symptoms, such as sudden, severe flank pain or hematuria (blood in the urine). A urologist will likely perform a urinalysis to check for signs of infection or crystal formation. To visualize kidney stones, clinicians rely on:
- Non-contrast CT scan: The gold standard for identifying the size and exact location of kidney stones.
- Ultrasound: Often used for pregnant patients or children to avoid radiation exposure.
- Blood tests: Used to check kidney function (creatinine levels) and rule out metabolic causes like hyperparathyroidism.
- Stone analysis: If a stone is passed or surgically removed, laboratory analysis determines its composition (e.g., calcium oxalate, uric acid), which is vital for preventing future kidney stones.
Which specialists diagnose kidney stones?
While an emergency room physician or primary care provider may identify kidney stones during an acute episode, a urologist is the specialist best equipped to manage and diagnose these conditions. If you experience recurrent kidney stones, seeing a urologist or a nephrologist is critical to investigate underlying metabolic or genetic factors that may be contributing to stone formation.
What conditions are confused with kidney stones?
Because the pain associated with kidney stones is often intense and localized to the abdomen or back, it is frequently confused with appendicitis, ovarian cysts, ectopic pregnancy, or gallbladder disease. Given the 13 members of the DiseaseMaps community who have shared their experiences, we understand that the diagnostic journey can feel isolating, especially if initial tests do not immediately reveal the cause of your pain.
Next steps
- Consult a board-certified urologist to discuss your symptoms and review imaging results.
- Request a 24-hour urine collection test if you have experienced multiple kidney stones to identify metabolic imbalances.
