文中提到针灸治疗有一些效果。用Moisture alarms训练一般有效果，不过可能需要几个星期到几个月的时间。另外尽量不要给孩子心理压力。在排除器质性疾病的前提下，实在不行再考虑药物治疗。

Treatments and drugs

By Mayo Clinic staff

Most children outgrow bed-wetting on their own. If there's a family history of bed-wetting, your child will probably stop bed-wetting around the age the parent stopped bed-wetting.

Generally, your child will be your doctor's guide to the level of necessary treatment. If your child isn't especially bothered or embarrassed by an occasional wet night, less aggressive treatments may be all that's needed. However, if your grade schooler is terrified about wetting the bed on a sleepover, he or she may be more motivated to try additional treatments.

Moisture alarms
These small, battery-operated devices — available without a prescription at most pharmacies — connect to a moisture-sensitive pad on your child's pajamas or bedding. When the pad senses wetness, the alarm goes off. Ideally, the moisture alarm sounds just as your child begins to urinate — in time to help your child wake, stop the urine stream and get to the toilet. If your child is a heavy sleeper, another person may need to listen for the alarm.

If you try a moisture alarm, give it plenty of time. It often takes at least two weeks to see any type of response and up to 12 weeks to enjoy dry nights. Moisture alarms are highly effective, carry a low risk of relapse or side effects, and may provide a better long-term solution than medication does.

Medication
If all else fails, your child's doctor may prescribe medication to stop bed-wetting. Various types of medication can:

• Slow nighttime urine production. The drug desmopressin acetate (DDAVP) boosts levels of a natural hormone (anti-diuretic hormone, or ADH) that forces the body to make less urine at night. The medication is available as a pill or nasal spray. However, the nasal spray isn't recommended for the treatment of bed-wetting because this form of the medication stays active for much longer, which can increase the risk of serious side effects. Although DDAVP has few side effects, the most serious is a seizure. This can happen if the medication is accompanied by too many fluids. For this reason, don't use this medication on nights when your child has had a lot of fluids. Additionally, don't give your child this medication if he or she has a headache, has vomited or feels nauseous.
• Calm the bladder. If your child has a small bladder, an anticholinergic drug such as oxybutynin (Ditropan) or hyoscyamine (Levsin) may help reduce bladder contractions and increase bladder capacity. Side effects may include dry mouth and facial flushing.
• Change a child's sleeping and waking pattern. The antidepressant imipramine (Tofranil) may provide bed-wetting relief by changing a child's sleeping and waking pattern. The medication may also increase the amount of time a child can hold urine or reduce the amount of urine produced. Imipramine has been associated with mood changes and sleep problems. Caution is essential when using this medication, because an overdose could be fatal. Because of the serious nature of these side effects, this medication is generally recommended only when other treatments have failed.

Sometimes a combination of medications is most effective. There are no guarantees, however, and medication doesn't cure the problem. Bed-wetting typically resumes when the medication is stopped.

Lifestyle and home remedies

By Mayo Clinic staff

Here are changes you can make at home that may help:

• Limit fluid intake in the evening. Limit your child's fluid intake during the evening. Around 8 ounces (about a quarter of a liter) or so in the evening is generally enough, but check with your doctor to find out what's right for your child. There's no need to limit your child's fluid intake, but some experts feel a good rule of thumb is for children to have 40 percent of their liquids between 7 a.m. and noon, another 40 percent between noon and 5 p.m. and just 20 percent of their daily fluids after 5 p.m. However, don't limit fluids if your child is participating in sports practice or games in the evenings.
• Avoid beverages and foods with caffeine in the evening. Caffeine may increase the need to urinate, so don't give your child drinks, such as cola, or snacks that have caffeine, such as chocolate, in the evening.
• Encourage double voiding before bed. Double voiding is urinating at the beginning of the bedtime routine and then again just before falling asleep. Remind your child that it's OK to use the toilet during the night if needed. Use small night lights so that your child can easily find the way between the bedroom and bathroom.
• Encourage regular urination throughout the day. During the day and evening, suggest that your child urinate once every two hours, or at least enough to avoid a feeling of urgency.
• Treat constipation. If constipation is a problem for your child, your doctor may recommend an over-the-counter stool softener.

Alternative medicine

By Mayo Clinic staff

Many people are interested in trying alternative therapies to treat bed-wetting, and several therapies, such as hypnosis and acupuncture, appear to be somewhat effective. However, other therapies currently don't have evidence to support their use.

• Hypnosis. Small trials of hypnosis coupled with suggestions of waking up in a dry bed or visiting the toilet in the night found that this therapy may help some children stay dry throughout the night.
• Acupuncture. This treatment involves the insertion of fine needles in specific parts of the body. Results of multiple studies have found that acupuncture is effective for some children.
• Diet. Some people believe that certain foods adversely affect bladder function and that removing these foods from the diet could help decrease bed-wetting. Limited research has not involved many subjects, and more study is needed.
• Chiropractic. The idea behind chiropractic therapy is that if the spine is out of alignment, normal bodily functions will be affected. However, convincing evidence is lacking regarding the use of chiropractic for the treatment of bed-wetting.
• Homeopathy and herbs. Although some people are interested in homeopathic remedies and herbal products, none of these has been proven effective in clinical trials. If you decide to try such a product, check with your child's doctor before giving it to your child, as some of these products may contain harmful ingredients or may interact with other medications your child is taking.

Coping and support

By Mayo Clinic staff

Children don't wet the bed to irritate their parents. Because your child's bed-wetting is involuntary, it's illogical to punish wet nights or reward dry nights. Try to be patient as you and your child work through the problem together.

• Be sensitive to your child's feelings. If your child is stressed or anxious, encourage him or her to express those feelings. When your child feels calm and secure, bed-wetting may become a thing of the past.
• Plan for easy cleanup. Cover your child's mattress with a plastic cover. Use thick, absorbent underwear at night to help contain the urine. Keep extra bedding and pajamas handy.
• Enlist your child's help. Perhaps your child can rinse his or her wet underwear and pajamas or place these items in a specific container for washing. Taking responsibility for bed-wetting may help your child feel more control over the situation.
• Celebrate effort. Don't punish or tease your child for wetting the bed. Instead, praise your child for following the bedtime routine and helping clean up after accidents.

With reassurance, support and understanding, your child can look forward to the dry nights ahead.
