BACKGROUND: Localisation of the non-palpable Implanon is useful to confirm its presence or to assist the surgeon with its removal. Previous studies have suggested that almost all non-palpable Implanon implants can be located with ultrasound in phantoms. AIM: To determine whether diagnostic ultrasound is a reliable method for localising non-palpable Implanon implant in-vivo. METHODS: Ultrasound was carried out to localise the non-palpable Implanon implant. To ascertain the accuracy of the ultrasound findings, all patients were followed-up until the implant was removed or until it was proven absent by serial progesterone levels confirming ovulation or by negative etonogestrel levels.
