    Abstract:
    In two groups of women the urethral pressure profile was recorded using a microtransducer catheter. Both groups were of approximately the same age, one consisting of continent women, the other of women with severe stress incontinence. Sixteen stress incontinent woman were examined before and after pubococcygeal repair and 10 of these were also examined during the operation. The two groups were compared for differences in the urethral pressure profile in the continent and incontinent states. The stress incontinent women had a significantly shorter functional length of the urethra (10 mm) but the same maximal urethral pressure as continent women. Remarkable changes in these parameters were seen during the operation. However, at the examination 3 months postoperatively, they had totally disappeared. The only change in the urethral pressure profile which persisted after the operation was a higher pressure in the proximal part of the urethra so that a urethral maximal pressure plateau had been established. This plateau was also seen, on a higher level, in the continent state.
