Clinical and ultrasonographic correlations following three surgical anti-incontinence procedures (TOT, TVT and TVT-O).

The aim of this study was to compare ultrasonographic findings on tape position, angulation and mobility following three surgical anti-incontinence procedures (trans-obturator tape (TOT), tension-free vaginal tape (TVT), tension-free vaginal tape obturator (TVT-O)) and to correlate these data with clinical signs of cures and failures and de novo voiding disorders. In this prospective study, vesicourethral static and dynamic analysis of 81 patients (30 TOT, 28 TVT, 23 TVT-O) were evaluated using introital ultrasonography. Width, position and appearance of the tape were similar in all three groups, i.e. like a "V" at rest, round angulation on Valsalva and closed angulation at maximum retaining. Moreover, closer angulation on Valsalva was associated with voiding disorders. Closer angulation at retaining was associated with de novo urge incontinence. Larger angulation of the tape at rest appeared to be significantly associated with recurrent stress incontinence. Ultrasonography could a be useful tool assessing anti-incontinence procedures and investigating post-operative voiding disorders.
