Mirena, a new intra-uterine device (IUD) introduced in Israel during the past year, releases 20 mcg/day of levonorgestrel for 5 years. It has the advantages of reduced pregnancy rates and diminished menstrual blood loss, together with a low risk of pelvic inflammatory disease compared with current IUD's. It has a typical sonographic appearance, differing from that of regular IUD's, which was demonstrated in all 15 women examined in this study. Its sonographic appearance includes both proximal and distal ends of the vertical arm of the device, which extend into the internal cervical os and fundal region, respectively. Acoustic shadowing between both ends defines the location of the device, which should help avoid consultations due to "lost IUD's."

D008598	Menstruation	The periodic shedding of the ENDOMETRIUM and associated menstrual bleeding in the MENSTRUAL CYCLE of humans and primates. Menstruation is due to the decline in circulating PROGESTERONE, and occurs at the late LUTEAL PHASE when LUTEOLYSIS of the CORPUS LUTEUM takes place.

D000292	Pelvic Inflammatory Disease	A spectrum of inflammation involving the female upper genital tract and the supporting tissues. It is usually caused by an ascending infection of organisms from the endocervix. Infection may be confined to the uterus (ENDOMETRITIS), the FALLOPIAN TUBES; (SALPINGITIS); the ovaries (OOPHORITIS), the supporting ligaments (PARAMETRITIS), or may involve several of the above uterine appendages. Such inflammation can lead to functional impairment and infertility.

D016912	Levonorgestrel	A synthetic progestational hormone with actions similar to those of PROGESTERONE and about twice as potent as its racemic or (+-)-isomer (NORGESTREL). It is used for contraception, control of menstrual disorders, and treatment of endometriosis.	18,19-dinorpregn-4-en-20-yn-3-one, 13-ethyl-17-hydroxy-, (17alpha)-(-)-,l-Norgestrel,Capronor,Cerazet,D-Norgestrel,Microlut,Microval,Mirena,NorLevo,Norgeston,Norplant,Norplant-2,Plan B,Vikela,duofem,D Norgestrel,Norplant 2,Norplant2,l Norgestrel
