[Evaluation of diagnostic methods in anatomic urinary incontinence in gynecology]

The present study was undertaken with the aim of verifying the value of diagnostic methods in female stress incontinence. In their diagnostic work the authors used urethrocystography, measuring of the urethral length and resistance. Displacement of the internal urinary meatus related to the interior border of the symphysis was also observed. In demonstrable incontinence the average posterior urethrovesical angle was 140 degrees, and in the absence of incontinence 120 degrees. It was also found that the difference between the pressure of the internal urinary meatus in straining and non-straining women with incontinence was +0,7 mm Hg and in those without incontinence +4,5 mm Hg. It has been observed, furthermore, that the relation between the vertical displacement of the internal urinary meatus in rest and stress was less than 5 in women with incontinence. In women without incontinence it was more than 5. There was no difference in the range of the urethral length in women either with or without stress incontinence.
