Pdf Summary

The aim of this study was to assess the interobserver repeatability of measurements obtained from three-dimensional endovaginal ultrasound (3D EVUS) in evaluating tape complications following incontinence mesh surgery. The study included 127 women with incontinence mesh-related probe complications. The women were imaged using 3D EVUS, and the measurements of urethral length, distance between the incontinence tape and bladder neck, distance between the incontinence tape and urethral lumen, and tape position in relation to the urethral rhabdosphincter were obtained from the images.<br /><br />The interobserver variability for the measurements was assessed using the interclass correlation coefficients (ICC). The results showed that the interobserver variability was excellent for the measurement of urethral length, distance between the middle of the tape and urethral lumen, and distance between the middle of the tape and bladder neck. However, there was only moderate correlation for the proximity of the sling to the urethral rhabdosphincter.<br /><br />The findings of this study demonstrate that 3D EVUS provides reproducible measurements of urethral length, as well as the distances between the mesh and bladder neck and urethral lumen. It also provides information on the relation of the mesh to the urethral rhabdosphincter. These measurements can be useful for peri-operative planning and may potentially be correlated with intra-operative findings.<br /><br />The authors suggest that further research can be done to assess the value of pre-operative pelvic floor ultrasound prior to mesh removal surgery and compare it to surgical findings and clinical outcomes. Overall, this study highlights the potential of 3D EVUS as a reliable tool for evaluating tape complications following incontinence mesh surgery.
