Credibility of Ultrasound Detection of Female Genital Prolapse Mesh

The aim of the study is to investigate the credibility of ultrasound in detection of synthetic polypropylene vaginal implants. In detail, the study investigates if the ultrasound examiner experience and the standard method of examination may affect the detection of synthetic polypropylene vaginal implants by ultrasound. The primary hypothesis is if 90% of prolapse mesh could be detected by the ultrasound examiners who are blinded to the previous prolapse surgery, the ultrasound is credible for prolapse mesh detection. The secondary hypothesis is if the ultrasound detection is not significantly different between the ultrasound examiners, the method of ultrasound examination is mandatory to acheive credible ultrasound detection of the prolapse mesh.
