    Abstract:
    BACKGROUND: This study was carried out to evaluate the urodynamic and ultrasonographic findings after tension-free vagina tape (TVT) procedure on stress urinary incontinent women. METHODS: Ninety women suffering from genuine stress incontinence without pelvic relaxation syndrome underwent surgery. Urodynamic measurement, one-hour pad test and introital ultrasonographic evaluation were performed preoperatively and one year after surgery. Additional ultrasonographic surveillance of the urethra was performed immediately after the operation. The position and mobility of the bladder neck was compared pre- and post-operatively in relation to the inferior edge of the pubic symphysis. RESULT: Eight women were excluded for various reasons. Among the 82 women who completed the study, 76 (93%) were cured, four were improved and two failed. No major intra- or post-operative complications occurred. The position and mobility of the bladder neck showed no significant difference before and after surgery. A urethral knee angle was noted ultrasonographically on cured and improved patients during maximum straining. Nine patients with immediate postoperative voiding difficulty were found to have a pronounced mid-urethra angulation. The symptom and sign were resolved by time after urethra depressing. Urodynamic assessment of the urethral pressure profile and other parameter showed no significant difference before and after the surgery except that a positive pressure transmission in the middle portion of the urethra was noted among 70 (87.5%) of cured and improved subjects. CONCLUSION: Tension-free vagina tape operation is an effective surgical procedure for the treatment of female urinary stress incontinence. The procedure seems neither to change hypermobility nor to elevate the position of bladder neck. Urinary continence after surgery is most probably achieved by creating a dynamic mid-urethral knee angulation by which the urethra is closed i.e. kinked at stress. Lifting of the mid-urethra resulted in postoperative voiding difficulty. It is the important that the tape is placed tension free under the urethra. Introital ultrasonographic surveillance is a suitable technique to visualize the result of the operation.
