101 women were studied, in the period from March 1997 to December of 1998, distributed into two groups, in accordance with the presence or not of urinary loss, being Group 1 (G1,5=51) with Urinary loss and Group 2 (G2,n=50) with no Urinary loss. These women were informed of the procedures to be done and signed a written consent for such evaluation.
The clinical evaluation included a clinical History, obstetric and gynecological, and a subjective evaluation of Urinary loss.
We used the pad test as an objective form of evaluating Urinary loss. The amount of ingested water before the test was pre determined and the pad, previously weighed, was given to the patient. After its placement, different activities were done, previously established. At the conclusion the pad was again weighed, so we could objectively get the amount of urine loss (the difference between the dry weight and the final weight). The result of this test was registered in grams 7. The statistical analysis of the charts were done through the Goodman test for contrasts between and in multinomiais proportions (STREINER 8, 1994) and in relation with the varied frequency of physical activities, number of urinations and number of losses per day, the non parametric test of Mann-Whitney 8 was used. All the statistical tests were done at the level of 0.05 of significance.
