Abstract:: In continent women, urethral pressure with stress events has been found to rise approximately 200 msec before pressure in the bladder begins to rise. We studied the time difference in incontinent women, women after successful and unsuccessful incontinence procedures, and continent women, to evaluate the timing of urethral pressure rises in correlation with continence status. We analyzed the urodynamic data of 20 incontinent patients before and after successful or unsuccessful (n = 10 each) Rat needle suspension. Ten continent women served as controls. The time difference between onset of the pressure increase in the urethra and in the bladder was noted before and after surgery. In all 10 continent women the pressure increase in the urethra started to rise approximately 160 msec before the pressure increase in the bladder. In 16 of 20 incontinent patients the pressure in the urethra and bladder rose simultaneously. Successful antiincontinence procedures restored the early onset of urethral pressure increases. Unsuccessful operations did not produce this effect. Successful antiincontinence operations permit timely compression of the urethra. This timely compression is associated with continence.
