Patient's question:
What is the reason for the subsequent occurrence of lower back pain and a foreign body sensation during urination?Doctor's answer:
Kidney stones are a very common disease, where "stones" form in the kidneys, ureters, or bladder. They not only cause pain and hematuria but can also lead to urinary tract infections. If the "stones" block the urinary tract for a long time, it can cause hydronephrosis and even damage kidney function. The incidence of kidney stones is relatively high in the elderly because, after aging, calcium loss from bones and osteoporosis cause a significant amount of calcium to enter the bloodstream and be excreted in the urine, resulting in increased calcium content in the urine and making it easier to develop kidney stones.Recommendations: Urinary tract stones are a common condition of the urinary system, including kidney stones, ureteral stones, urethral stones, and bladder stones. Kidney stones are composed of calcium oxalate, which can cause renal colic. Currently, doctors recommend reducing dietary calcium intake to prevent the recurrence of kidney stones. Adjust the dietary structure based on the composition of the stones to determine the preventive diet.
1. For uric acid stones, a low-purine diet should be adopted, and for bladder acid stones, a low-methionine diet should be followed. Fruits and vegetables can make urine alkaline, which is beneficial for preventing uric acid and cystine stones. Meat foods make urine acidic, which is good for preventing infection stones.
2. For phosphate stones, a low-calcium, low-phosphate diet should be adopted. For calcium-containing kidney stones, high-calcium, high-salt, high-oxalate, high-animal protein, high-animal fat, and high-sugar diets should be avoided.
3. Adopt a high-fiber diet. It is generally recommended that patients with kidney stones should consume less salt and animal protein, drink plenty of water, and maintain a urine output of 2,000–3,000 milliliters per day. This not only helps prevent the recurrence of kidney stones but also ensures adequate calcium intake, which is beneficial for other aspects of health.
