Kidney stones, also known as nephrolithiasis, are indeed solid masses that form in the kidneys. They are typically made of crystallized minerals and salts found in urine. The symptoms you've listed are quite common, which include severe pain in the lower back, abdomen, or side (known as renal colic), nausea, vomiting, fever, and the presence of blood in the urine. The pain can radiate to the groin area as well.

The causes of kidney stones can be varied, but the most common include:

1. Dehydration: Not drinking enough water can lead to concentrated urine, which is more likely to form crystals.
2. Diet: Eating too much sodium, sugar, or animal protein can increase the risk.
3. Obesity: Being overweight can increase the chances of developing kidney stones.
4. Certain medical conditions: Such as gout, diabetes, and high blood pressure can also contribute.
5. Genetic factors: There's often a family history of kidney stones.
6. Some medications: Certain medications can increase the risk of stone formation.

Diagnosis of kidney stones is typically done through imaging tests such as X-rays, ultrasounds, or CT scans. The treatment for kidney stones depends on their size and location. Smaller stones may pass out of the body with increased fluid intake and medication to help with the pain. Larger stones may require more invasive treatments:

- Shockwave lithotripsy: This is a non-invasive procedure that uses sound waves to break up the stone into smaller pieces that can be passed in the urine.
- Ureteroscopy: This involves using a small scope to remove or break down the stone.
- Percutaneous nephrolithotomy: A small incision is made in the back to remove the stone directly.
- In some cases, open surgery may be necessary if the stone is very large or if other treatments don't work.

Prevention is often the best approach, and it includes:

1. Drinking plenty of water: At least 8-10 glasses a day to keep urine diluted.
2. Eating a balanced diet: Limit foods high in oxalates (like spinach and rhubarb) and salt.
3. Maintaining a healthy weight: This can reduce the risk of developing kidney stones.
4. Regular exercise: Helps in maintaining a healthy body and promotes urine production.
5. Limiting certain beverages: Such as soda and tea, which can increase the risk of stone formation due to their oxalate content.

If you suspect you have kidney stones or are experiencing symptoms, it's important to consult with a healthcare professional for proper diagnosis and treatment. They can also provide advice tailored to your specific situation to help prevent future occurrences.
