Causes and Diagnoses of Kidney Stones
Kidney stones form when urine contains an excess of crystal-forming substances, including calcium, oxalate and uric acid. Numerous conditions can be related to the formation of kidney stones, such as:
- Dietary imbalances
- Side effect of medications and supplements
- Chronic dehydration
- Hereditary factors
- Multiple endocrine neoplasia or Von Hippel-Lindau syndrome
- Renal tubular acidosis
- Inflammatory bowel disease
Diagnosing kidney stones
Diagnostic tests for kidney stones may include:
- Intravenous pyelogram (IVP): Special dye is injected into one of your veins and X-rays are taken as the dye passes through your urinary tract, allowing your physician to see tumors, kidney stones, blocked areas as well as blood flow through the kidneys.
- Lab tests: Your passed stones can be analyzed to determine their chemical make-up.
- Pelvic or urethral ultrasound: This imaging test uses high-frequency sound waves to create an image of the organs.
- Pelvic multi-resonance imaging (MRI): Using a combination of large magnets, radiofrequencies and a computer, an MRI produces detailed images of organs and structures within the body.
- Urinalysis: Your urine will be checked under a microscope for the presence of infection or blood.
