The intensity of the pain that comes on when a small stone (calculus) tries to make its way through the urinary tract cannot be described in simple words. Severe, excruciating, gut wrenching are just some words that can come near to describing this pain. You can avoid this pain by knowing why renal calculi are formed and what you can do to prevent them.
Renal calculi are deposits of small, hard particles formed inside your kidneys. The stones are mainly composed of minerals and acid salts. Often, they are formed when the urine becomes too concentrated, allowing minerals and salts to crystallize and stick together.
Types of stones:
Calculi are broadly classified into two major groups, radio-opaque and radiolucent. Radio-opaque calculi are visible on standard x-rays while radiolucent calculi can not be detected on standard x-rays. They are visible only on CT Scans. The examples of radio-opaque calculus are Calcium Oxalate, Calcium Phosphate and Struvite calculi. Common radiolucent calculi include Uric Acid, Triamterene and Xanthine stones.
What symptoms may be present when one has renal calculi?
- Pain that radiates to the groins
- Pain that comes in waves
- Pain while passing urine
- Pink or red urine
- Cloudy urine
- Difficulty passing urine
Simple tips to prevent kidney stones:
- The most effective non-medication therapy for this problem is increasing fluid intake. If you live in a dry and hot climate or if you exercise frequently, you should drink even more water to produce a sufficient amount of urine. The best way to know if you are drinking enough water is to check the appearance of your urine. If it is clear and light, you’re drinking enough water.
- Medical experts advise patients to decrease their protein intake because excess proteins in the body can contribute to calcium based and uric acid stones. It is best to limit the intake to maximum 8 ounces of pork, beef, poultry or fish per day.
- Most patients stop consuming foods containing calcium. However, it has been proved that calcium in food does not affect your risk of calculi. So, you can continue eating calcium-rich foods. But, you should avoid taking calcium supplements when not required otherwise.
- Decrease your intake of Oxalate especially if you have a tendency to form calcium oxalate stones. Oxalate rich foods include rhubarb, beets, spinach, chocolate, tea and peanuts.
Drugs that prevent kidney calculus:
Passing kidney stones in urine can be unbearably painful. Depending on the composition of the calculus, you may need to take medications like Zyloprim. This medication contains allopurinol and works by preventing the production of uric acid.
Patients are usually prescribed Zyloprim in a dose of 200 to 300 mg per day. You should consult your doctor to know the right dose suitable for your specific condition.
If you have someone close in your family with a history of renal calculi, you have more chances of developing it. Dietary modifications and oral medications like Zyloprim can help reduce or eliminate the chance of this condition.
