Treatments for Cystinuria?
Treatment starts with doing things to keep stones from forming. For adults and children, this means drinking more water, reducing salt, and eating less meat. If these steps are not enough, you may also need to take special medicine to help keep stones from forming.
- Drinking more water. Drinking lots of water will lower the ability for cystine to form stones in the urine. Ask your healthcare provider how much water you should drink each day to help keep stones from forming.
- Changing your diet. It is easier for cystine stones to form as urine becomes more acidic. Eating more fruits and vegetables can make the urine less acidic. Eating meat produces urine that has more acid, which can increase your risk for cystine stones.
- Reducing salt. Eating less salt can help keep cystine stones from forming. Try not to eat salty foods, including potato chips, french fries, sandwich meats, canned soups, and packaged meals.
- Medicine. Some people may also need to take prescription medicine to help keep stones from forming. Different medicines work in different ways. Some types help to keep your urine less acidic. Other types help keep cystine stones from forming by not allowing crystals to come together. Your healthcare provider can explain these different options and help you find the right medicine for you.
- Soak in a hot bath, use a hot water bottle or heat pad. The heat is a good form of pain relief.
- Keep busy, talk to people, use diversionary tactics. This may sound easier than it is to do but for long term or persistent pain this is a good habit to get into.
- Keep drinking. This is a recurring theme. Although it may increase the pain in the short term, it will make the pain go quicker.
- Go for a run, walk round the block or go swimming. Again, although you may not feel like doing this, if you are able it helps to relax the muscles and reduce the muscle spasms.
Some Suggestions For Moving Stones Quickly
With all stones it is important, before you make the decision to encourage the stone to move, to ensure that the stone is small enough to pass through your tubes and not to cause an obstruction. For stones that are too large to be passed naturally other forms of stone removal are probably best. Take advice from your doctor before trying any of these methods.
- Get and use pain relief promptly. Don’t wait until it is really bad. The quicker you take the medication the more use it will be.
- Keep drinking. This may be the last thing you want to do with renal colic, but it is the only way to keep those stones rolling.
- Go for a run or walk round the block. Again, probably the last thing you want to do but it gets the muscles in that area moving.
