Introduction and hypothesis Our aim was to use threedimensional enodovaginal ultrasound (3D EVUS) to identify sonographic parameters that are associated with successful outcomes following injection of Macroplastique. Methods Three hundred and sixty degree 3D EVUS was performed in 100 treatment-naïve patients following Macroplastique injection. The location, volumes, periurethral distribution, and distance of the hyperechoic densities from the urethrovesical junction were assessed. The patients were divided into two groups: group A (n072): patients who had good clinical outcome and group B (n028): patients who were not improved or worsened. The two groups were compared with respect to the ultrasound parameters measured. Results Group A had a greater proportion of women with Macroplastique located in the proximal urethra, while midurethral location was found to be significantly more frequent in group B (p00.036). The odds of a circumferential periurethral distribution in group Awere 13.62 times the odds in group B (95% CI: 5.12-56.95). When the location of the injection and the type of periurethral distribution were considered together, it was found that when the site of injection was proximal, the odds of circumferential distribution in group A was significantly greater than those in group B (odds ratio [95% CI]: 22 [3.05-203.49]; p<0.001). Conclusion Proximally located Macroplastique and circumferential periurethral distribution of Macroplastique are individually associated with successful outcomes following the injection. The combination of circumferentially distributed and proximally located Macroplastique is associated with the best short-term clinical outcomes. © The International Urogynecological Association 2012.
