In recent years, many factors involved in female urinary incontinence etiopathogeny have been extensively studied leading to better treatment and results.
While reviewing literature we found considerable evidence suggesting that 70% of urinary leak complaints begin during menopause. This lead to the question: If increase in urinary incontinence prevalence was due to the decrease in estrogen levels during menopause or if it was just part of the aging process 20. In our study, we noted that the majority of patients showed symptoms beginning in the peri and post-menopause periods.
Our findings showed that body mass index was higher for incontinent women; this agrees with literature21.
Information from clinical history showed a predictive value of approximately 70% to stress urinary incontinence. It was not possible to perform this evaluation in patients with urge incontinence, reinforcing the necessity for complementary exams in these cases 22,23. Clinical history is therefore not trustworthy for obtaining a precise diagnosis. This is due mainly to the fact that urinary tract symptoms usually overlap and are not specific. We could however isolate some significant aspects using information from the clinical history. The number of daily micturitions in the incontinent Group is significantly higher than the continent group. In spite of the difference in number of daily micturitions between the groups, the quantity of liquid ingested per day was not significantly different.
The number of nycturia episodes in the incontinent group was significantly higher than the continent group.
Several authors 5,24 have described the presence of vaginal prolapse as a predisposing factor to urinary incontinence; this was confirmed in our study.
This study demonstrates low concordance between objective and subjective evaluation. However clinical history and subjective patient evaluation are still important information and should be considered in the evaluation and treatment of urinary incontinent patients.
