Female urinary incontinence ( UI ) is defined by the International Society of Continence (ISC) as an unvoluntary urine leak, demonstrated objectively, which causes social and hygiene problems 1. It may occur by the loss of the anatomical support of the urethra and the bladder 2, that causes urethral hypermobility and it constitutes the most frequent cause of UI, responsible for 90% of the cases 3. Another less frequent cause of UI is the urethral sphincter intrinsic deficiency ( 10% of the cases ), due to the loss of the coaptation of the mucous ( mucous seal ), due to the low level of estrogen observed in menopause. Previous surgeries for correction of UI, myelodysplasia and neurological lesions, also associated are intrinsic sphincter deficiency 4.
The predominance of UI depends on several factors: age, deliveries, hormonal status 4 as well as the investigation method and the type of studied population ( institutionalized or not)5 the occasional urinary loss in students at a lower age of 30 varies from 51 to 52% of the cases 6,7,8. In women between 30 and 60 years of age it was observed a prevalence of urinary incontinence that varied from 14 to 41% 5,8,9,10,11,12,13,14 with an average of 24.5% 10,11,12,13.
Our objective was to evaluate the prevalence or urinary incontinence in women attended at the general outpatient clinic of the Botucatu School Health Center - UNESP.
