Purpose: The transobturator adjustable tape (TOA) allows adjustment of tension after surgical intervention, thus permitting correction of postoperative incontinence or obstruction. The aim of this study was to compare the efficacy and safety of TOA versus transobturator tape (TOT) for the treatment of stress urinary incontinence with intrinsic sphincter deficiency (ISD).
Materials and Methods: Patients underwent TOA (n=33 with ISD) or TOT (n=47 with ISD) insertion by one experienced surgeon. The patients were considered to have ISD on the basis of a Valsalva leak point pressure <60 cmH2O or a maximum urethral closure pressure <20 cmH2O. The preoperative evaluation included history taking, physical examination, voiding diary, stress and 1-hour pad tests, and a comprehensive urodynamic examination. Postoperative evaluation included a stress test, 1-hour pad test, questionnaire, and uroflowmetry with postvoid residuals.
Results: After 6 months of follow-up, the rate of cure (TOA, 75.6% vs. TOT, 72.3%) was similar between the two groups. The rate of satisfaction was not significantly higher in the TOA group than in the TOT group (84.8% vs. 78.7%; p=0.05). Four patients in the TOA group (12.1%) needed a reduction in tension because of urinary obstruction (flow <10 ml/sec and/or residual urine >50 ml). The tension of the mesh was tightened in 5 patients (15.2%) because of the persistence of a certain degree of incontinence. The residual urine volume at postoperative 7 days was significantly lower in the TOA group than in the TOT group (19.5 ml vs. 41 ml; p=0.016, repeated-measures analysis of variance test).
Conclusions: The TOA allows postoperative readjustment of the suburethral sling pressure for a number of days after surgical intervention, which allows for the achievement of good short-term results. These data suggest that better lower obstructive voiding symptoms than those achieved with the traditional nonadjustable mesh can be obtained with the TOA.
