Temporal separation of cough-induced urethral and bladder pressure spikes in women with urinary incontinence.
The time separation of cough-induced urethral and bladder pressure spikes were studied in 32 female patients: 16 with urinary incontinence due to sphincter incompetence, 9 with urinary incontinence and a competent urethral closure mechanism, and 7 after incontinence surgery. There were no significant differences in time separation between the three groups at different positions in the urethra. Age and menopausal status did not affect time separation of pressure spikes. It is concluded that time separation of pressure spikes during cough cannot be used as a discriminator of the etiology of urinary incontinence. Surgery does not restore the latency seen in normal continent women and may restore continence by a mechanism different from that of normal continent women.
