To explore the significance of location and tension of transobturator suburethral tapes in surgical outcomes using four-dimensional (4D) ultrasound
Fifty-six women having undergone transobturator suburethral tape procedures were enrolled. Tape location and tape tension were assessed by 4D ultrasound at rest, on straining, and during coughing. Ultrasound parameters representing tape location included the sagittal tape-symphysis pubis distance (sTSD), sagittal tape-symphysis pubis angle (sTSA), and tape percentile, while those representing tape tension included urethral encroachment, sagittal tape-urethra distances at the upper end (sTUDu), center (sTUDc), and lower end of the tape (sTUDl), and axial urethral central echolucent area at the tape center (aUCEAc).
In success cases during increased intra-abdominal pressure, the sTSA and the incidence of urethral encroachment increased, while the sTUDu, sTUDc, sTUDl, and aUCEAc decreased. Women who reported postoperative SUI had lower tape percentile and demonstrated no ultrasound manifestation of urethral encroachment at rest and during increased intraabdominal pressure. Women with postoperative overactive bladder symptoms had shorter resting sTSD and larger resting sTSA. Women reporting postoperative de novo or worsening voiding difficulty had larger resting sTSA and higher incidence of urethral encroachment at rest.
Both tape location and tape tension are associated with surgical outcomes of transobturator suburethral tape procedures. The assessments for the location and tension of the suburehtral tapes can be fulfilled by 4D ultrasound.
