OBJECTIVE To evaluate clinical implications of the unicornuate uterus and rudimentary horn. METHODS A retrospective study. METHODS A university hospital. METHODS Forty-two women who had a unicornuate uterus with or without rudimentary horn. METHODS The rudimentary horn was removed in 21 cases. METHODS Presence of other anomalies, fertility, and outcome of pregnancies were studied. RESULTS A right unicornuate uterus with noncommunicating rudimentary horn was the most common type of uterine anomaly. Unilateral renal agenesis was found in 13 (38%) of 34 cases. Six (14%) of the 42 patients had primary infertility. Thirty-four women produced 93 pregnancies; ectopic pregnancy (EP; rudimentary horn, tubal) occurred in 20 of these cases (22%). The pregnant uterine horn ruptured in 3 of 7 cases. Eight (57%) of the 14 women with infertility underwent treatment by IVF-ET; 4 of them conceived, and 2 had term delivery. The fetal survival rate was 61%, prematurity 17%, fetal growth retardation 5%, and the spontaneous intrauterine (IU) abortion rate was 16%. Pregnancy-induced hypertension (PIH) was more common in women lacking a kidney than in those with two kidneys. CONCLUSIONS The high number of EPs indicates removal of rudimentary horn and its tube when diagnosed. The prognosis of IU pregnancy is not impaired in the unicornuate uterus although prematurity threatens. Unilateral renal agenesis is associated with PIH.

UI	MeSH Term	Description	Entries
D007246	Infertility	A reduced or absent capacity to reproduce.	Sterility,Reproductive Sterility,Sterility, Reproductive,Sub-Fertility,Subfertility
D007668	Kidney	Body organ that filters blood for the secretion of URINE and that regulates ion concentrations.	Kidneys
D007752	Obstetric Labor, Premature	Onset of OBSTETRIC LABOR before term (TERM BIRTH) but usually after the FETUS has become viable. In humans, it occurs sometime during the 29th through 38th week of PREGNANCY. TOCOLYSIS inhibits premature labor and can prevent the BIRTH of premature infants (INFANT, PREMATURE).

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D010053	Ovary	The reproductive organ (GONADS) in female animals. In vertebrates, the ovary contains two functional parts: the OVARIAN FOLLICLE for the production of female germ cells (OOGENESIS); and the endocrine cells (GRANULOSA CELLS; THECA CELLS; and LUTEAL CELLS) for the production of ESTROGENS and PROGESTERONE.	Ovaries
D011247	Pregnancy	The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.	Gestation,Pregnancies
D011256	Pregnancy Outcome	Results of conception and ensuing pregnancy, including LIVE BIRTH; STILLBIRTH; or SPONTANEOUS ABORTION. The outcome may follow natural or artificial insemination or any of the various ASSISTED REPRODUCTIVE TECHNIQUES, such as EMBRYO TRANSFER or FERTILIZATION IN VITRO.

D011271	Pregnancy, Ectopic	A potentially life-threatening condition in which EMBRYO IMPLANTATION occurs outside the cavity of the UTERUS. Most ectopic pregnancies (>96%) occur in the FALLOPIAN TUBES, known as TUBAL PREGNANCY. They can be in other locations, such as UTERINE CERVIX; OVARY; and abdominal cavity (PREGNANCY, ABDOMINAL).

D004624	Embryo Transfer	The transfer of mammalian embryos from an in vivo or in vitro environment to a suitable host to improve pregnancy or gestational outcome in human or animal. In human fertility treatment programs, preimplantation embryos ranging from the 4-cell stage to the blastocyst stage are transferred to the uterine cavity between 3-5 days after FERTILIZATION IN VITRO.

D004715	Endometriosis	A condition in which functional endometrial tissue is present outside the UTERUS. It is often confined to the PELVIS involving the OVARY, the ligaments, cul-de-sac, and the uterovesical peritoneum.	Endometrioma,Endometriomas,Endometrioses
