Original researchComputer-assisted virtual urethral pressure profile in the assessment of female genuine stress incontinence
Section snippets
Materials and methods
A total of 31 women complaining of urinary loss during stress and seen in the urogynecologic unit of the Department of Gynecology, Martin-Luther-University Halle-Wittenberg between July 1999 and December 1999 were enrolled in our study. Moreover, 30 healthy and symptom-free women admitted to our hospital because of other gynecologic diseases (uterine bleeding, n = 17; breast cancer, n = 13) served as controls. All subjects gave written informed consent for the urogynecologic investigations. The
Results
Group-specific demographic descriptions of continent women and patients with genuine stress incontinence are presented in Table 1. According to the results of our urogynecologic evaluation, we identified two groups of women. As was to be expected, no incontinence was present during urogynecologic investigation in 30 symptom-free women (group A). Genuine stress incontinence was present in 31 symptomatic patients (group B). No difference between group A and B patients was found for Pclo and for
Discussion
Compared with conventional urethral pressure profile measurements at rest, significant differences for all parameters of computer-assisted virtual urethral pressure profile were found in our study between patients with genuine stress incontinence and continent women. The famous physician Heisenberg stated in 1927 that no object in nature can be measured without being deranged and transformed.12 Urethral pressure measurements by means of a transurethral catheter take place in a totally
