[Stress urinary incontinence in women. Epidemiologic inquiry. Apropos of 500 cases].

Nearly 50% of women in Tunisia have urinary incontinence, and 30% of these are highly embarassed. This condition is under-estimated in Tunisia by doctors in as far as its functional effects are concerned because the country has other diseases which are more urgent and take priority. Stress incontinence causing invalidism is very frequent: 31.4%. The principal factors that lead to it are home delivery, multiparity, menopause and large babies. There are two frequent associated conditions: incontinence during pregnancy and cystocoele. A contribution is made by the clinical diagnosis, but if investigations stop there a definite diagnosis cannot be made and therefore there is a risk of failure of treatment. In fact the treatment should be according to the cause: it is medical when are purely urinary troubles and surgical or physiotherapeutic when there is true stress incontinence. The best treatment would be to prevent the condition by good obstetrics and this by better methods of delivering the babies.
