Preventing kidney stones

I was recently admitted to hospital in agony and was diagnosed with a kidney stone. Eventually it passed on its own but I never want to go through that pain again. What can I do to prevent it?

Kidney stones are extremely common. About one in 20 women in the UK will develop a kidney stone at some stage in their life. No-one knows why some people get them but the stones result from tiny crystals in the urine clumping together and blocking the tube that runs from the kidney to the bladder. Most stones are small and pass through the system naturally in a day or so.

To prevent new stones forming, the most important thing is to drink plenty of water. I would recommend two to three litres a day. This keeps the urine diluted and prevents a build-up of the chemicals that can cause kidney stones.

If you do get a recurrence, it would be useful to ask your doctor to analyse the chemical composition of the kidney stone and check the levels of calcium and uric acid in your blood. This would enable the doctor to give you advice on how to alter your diet. For instance, if you had a calcium-based stone – the type which accounts for 80 per cent of stones – it would be advisable to limit your intake of oxalates. These are naturally occurring chemicals that combine with calcium and can lead to kidney stones. Oxalates are found in meat, chicken, fish such as anchovies and herring, asparagus, berries, chocolate, spinach and rhubarb. Strangely enough, your actual calcium intake has little to do with whether you develop the condition.

Urinary incontinence

Where can I get information about treatment for urinary incontinence? My GP says he can refer me to the hospital, but I’d like to know what my options are before I go ahead.

Urinary incontinence is an incredibly common problem, affecting one in three women at some stage in their lives. Treatment depends on several factors, including your age, whether you've completed your family, whether you have ‘urge' or ‘stress' incontinence and so on. Most areas now have a specialist incontinence nurse adviser, who will be able to give you advice on the right way to do pelvic floor exercises. If they're done correctly, two-thirds of women improve so much they need no further treatment. Have a chat with your GP or practice nurse about being referred.

Stress incontinence

I had my first baby six months ago, and ever since I’ve suffered from stress incontinence when I sneeze or run. Almost worse, though, my vagina feels really loose when my husband and I make love. Are the two connected?

Yes, these symptoms are almost certainly connected and, although it might sound strange, this is actually good news because you can use the same treatment for both problems. When you deliver, the muscles and supportive structures of your pelvic floor take a lot of strain and - unless you're really obsessional about your pelvic floor exercises - stress incontinence can be a real problem. It affects around one in three women at some point in their lives but, fortunately, it's never too late to do something about it. First of all, make an appointment to see your GP, to rule out other causes and to ask about the options. Your doctor may be able to refer you to a specialist physiotherapist, who can give you exercises to practise. Electrical stimulation and vaginal cones of gradually increasing weight can also be very effective.

Urine infections

I’ve had blood in my urine twice in the past 18 months. Both times I felt generally unwell and had a burning sensation when I went to the loo. My GP told me the blood was due to an infection and that I don’t need to worry. But it happened again last week and, although antibiotics cleared it up, I keep thinking it could be something more sinister.

I'm delighted to be able to reassure you. If your doctor has confirmed that you had a urine infection and it settled down with antibiotics, there's no need to worry. Urine infections cause inflammation of the lining of your bladder, which then often bleeds. If you pass blood without pain, though, or if a urine sample shows blood but no evidence of infection, you would need further investigations.

Will cranberry juice help?

I frequently get cystitis, and one of my friends swears by cranberry juice. Can it really make a difference?

Yes, your friend is right. It sounds like an old wives’ tale, but actually has a strong scientific basis. Women are more likely than men to suffer from cystitis – more than three out of five women will get it at some point – and at least one in three women who get cystitis will have another attack in the next 12 months. This recurrent cystitis is most common in women in their 20s and those over 55, but there’s increasing evidence that drinking cranberry juice can help women who suffer from frequent bouts. This may be due to one of the ingredients in the juice that stops bugs from sticking to the lining of the bladder, making it easier for your body to flush them out. Whatever the reason, it’s well worth drinking a couple of glasses of cranberry juice a day. A variety with at least a 25% concentration of fruit is best, and there are low-sugar versions available if you’re watching your weight.

Easing cystitis

I suffer from frequent bouts of cystitis. Are there any alternative treatments apart from cranberry juice, which I’ve never found to be particularly helpful?

Cystitis is extremely common – over two million women in the UK suffer from it every year. Antibiotics will usually clear it up, but many women, like you, have recurring bouts and want a drug-free alternative.

It’s vital to drink plenty of fluids and limit your intake of tea, coffee and alcohol, which are dehydrating and can increase the acidity of urine. Bacteria love warm, airless conditions, so wear loose cotton clothing and cut down on sugar in your diet, as sugar encourages the growth of bacteria. Avoid perfumed toiletries too and pass urine as soon as you feel the need. If an attack starts, take a powder such as Canesten Oasis (available nationwide), which makes urine less acidic. For more advice, contact the Cystitis and Overactive Bladder Foundation (www.cobfoundation.org; 01908 569169).
