Transobturatory tension-free composite sling for urethral support in patients with stress urinary incontinence: favorable experience after 1 year follow up.

OBJECTIVE

Symptomatic, anatomic and urodynamic results of a composite transobturatory tension-free sling with an absorbable middle part, in patients with stress urinary incontinence (SUI), were studied.

METHODS

A prospective study in 40 women with SUI was performed. Symptoms, urodynamics and anatomical improvements were evaluated separately. Surgery was performed with the transobturatory approach.

RESULTS

All patients had both clinically and urodynamically confirmed SUI. Clinical outcome was favorable in 36/40 (90%) patients, after 1 year. Operation improved the position of the bladder neck (2.8 cm and 1.4 cm below the pubic bone, respectively) and significantly decreased mobility of the bladder neck during abdominal straining (3.3 cm and 1.7 cm, respectively). Both symptoms and quality of life were significantly improved 1 month after the surgery. Postoperative maximum flow was lower than the preoperative one but with borderline significance (25.8 and 23.7 mL/s; P = 0.05). Pressure flow study showed unobstructed voiding both preoperatively and postoperatively. Detrusor pressure at the maximum flow was increased (20, 4 and 22, 8 cmH(2)O, respectively) but not significantly.

CONCLUSION

Our results confirmed a high objective cure rate, improvement of symptoms and quality of life, and at the same time, corrected position of the bladder neck and unobstructed voiding.
