It has been demonstrated that when urethral pressure profiles are measured with microtip transducers on relatively stiff catheters, there is an important difference in the profile when measured with the transducers facing anteriorly and posteriorly. It has been suggested that patients with demonstrable genuine stress urinary incontinence had notably lower posteriorly derived urethral pressure profiles than anteriorly derived pressure profiles. A clinical consideration of this factor has been studied in 25 patients; 19 had accepted urodynamic evidence of genuine stress urinary incontinence and 6 did not. The use of posteriorly derived pressure profiles in comparison with anteriorly derived as a test for genuine stress urinary incontinence showed a sensitivity of 84% and specificity of only 33.3%. However, when correlated with patients showing lack of anatomic support of vaginal and paraurethral structures, the sensitivity and specificity is significant. Anatomic considerations leading to these findings are suggested.
