Kidney stones, if mobile within the kidney, can cause intense pain in the patient's lumbar and abdominal area, clinically referred to as renal colic. Patients often experience unbearable pain, heavy sweating, along with symptoms such as nausea and vomiting. In such cases, it is crucial to seek timely treatment at the hospital's urology department. Doctors will use medications to alleviate pain and spasm. If there is nausea and vomiting, antiemetic drugs will also be used to relieve symptoms. Once diagnosed with kidney stones, patients are advised to seek treatment at a hospital as soon as possible.

Do kidney stones hurt?

Whether kidney stones cause pain depends on whether the stones are moving within the kidney. If the stones are relatively large, they generally do not move within the kidney, and the patient will not feel pain. However, when the stones cause hydronephrosis (accumulation of water in the kidney), the patient may occasionally feel a slight swelling and discomfort in the lower back. If the kidney stones are small, they are likely to move within the kidney, which can lead to severe lower back pain, clinically known as renal colic. This pain is quite severe, and it is necessary to go to the hospital for timely treatment.

Are kidney stones severe?

The severity of kidney stones depends on the size of the stones and their location. For example, stones within the kidney parenchyma, if not large and not moving, generally do not cause much trouble. However, if the stones block the area of the renal pelvis and calyces, or even move downward to block the ureter, causing the urine produced by the kidneys to not be excreted smoothly, it will cause the patient to experience renal colic. This type of pain is very intense, radiating to the back and causing abdominal pain, as well as pain in the perineal area. Patients often may also experience fever and other clinical symptoms. Prolonged obstruction of the urinary system can lead to renal failure, which is quite dangerous.

What should not be eaten with kidney stones

Patients with kidney stones do not have absolute dietary prohibitions. However, it is advisable to consume less food high in calcium, oxalates, and purines. Foods high in purines are mainly found in seafood, animal offal, beer, and beverages. High-calcium foods are primarily found in soy products and dairy products, such as soy milk, tofu, and cow's milk. Foods high in oxalates include celery, spinach, etc. These foods can be consumed in moderation in daily life, but should not be used in large amounts over a long period to avoid further growth and increase of stones. It is also important to drink plenty of water, urinate frequently, and engage in appropriate physical exercise to effectively prevent the occurrence of kidney stones. Additionally, for patients who have already developed kidney stones, it is necessary to timely decide on conservative stone expulsion or surgical treatment based on the size of the stones.

Does kidney stones cause hematuria?

Kidney stones can cause hematuria. The main reason that kidney stones cause hematuria is due to the damage to the mucous membrane of the renal pelvis caused by the stones, and even the rupture of blood vessels, leading to hematuria. In this case, it is necessary to use imaging methods such as color Doppler ultrasound and CT to determine the exact location and size of the stones. If the stone is small, such as about five or six millimeters, symptomatic hemostasis treatment can be conducted, and if necessary, drinking more water, urinating frequently, exercising more, and taking oral stone-discharging granules or effervescents can help expel the stones from the body. If the stone is large, it is advisable to opt for surgical treatment as soon as possible.

Are urinary stones the same as kidney stones?

Urinary stones and kidney stones are not exactly the same. Urinary stones refer to stones in the urinary system, including kidney stones, ureter stones, bladder stones, and urethral stones. Therefore, kidney stones are just one type of stones in the urinary system, and urinary stones include kidney stones. If kidney stones occur, one should promptly visit the hospital's urology department for examinations such as ultrasound or CT scans. This facilitates understanding the specific size, location, number of stones, and whether there is accompanying hydronephrosis or infection, allowing for targeted treatment. If the stones are small, drinking plenty of water, urinating frequently, and exercising can help expel the stones from the body. If the stones are large, or there is hydronephrosis, it is advisable to consider surgery as soon as possible.
