Single use disposable Uterine Sound is a malleable, silver plated instrument used for probing and dilating the uterus as well as measuring the length of the cervical canal.The instrument is available with or without graduated centimeter markings.Uterine sounds are inserted into the woman’s uterus from the cervix so that the length of the uterus can be determine and to find out what direction the uterus and the cervical canal.
Uterine sounding may be performed prior to embryo transfer to determine the uterine depth and how easily an embryo transfer catheter can be passed through the cervix. In this case, it may also be called a trial transfer. It is performed prior to insertion of an intrauterine device (IUD) in order to measure the length and direction of the cervical canal and uterus. This reduces the risk of perforating the uterus with the IUD. This may occur when the IUD is inserted too deeply or at the wrong angle.
