RESUMO
OBJECTIVE: To investigate the clinical characteristics of symptoms, diagnostic procedures, infertility, obstetrical complications, and surgical corrections in women with congenital uterine anomalies. METHODS: Between January 1990 and December 2007, 110 patients diagnosed with uterine anomalies from Kangnam St. Mary's Hospital, the Catholic University of Korea were included in this study. The charts of patients were reviewed retrospectively for uterine anomaly type, clinical symptom, diagnostic workup, fertility, fetal presentation, and uteroplasty. Congenital anomaly was categorized according to classification by the American Fertility Society (1988). RESULTS: Uterine anomaly was noticed in 1 in 752 patients (0.13%) who visited the inpatient department. The diagnosis was made by pelvic ultrasonography and manual examination (45.5%), incidental discovery during Cesarean section (24.5%), and other surgical procedures and salpingography. Most common types of uterine anomaly were bicornuate uterus (42 cases, 38.2%) and uterine didelphys (39 cases, 35.5%). Renal anomaly was accompanied in 21 patients (19.1%), frequently associated with bicornuate uterus and uterine didelphys. Uteroplasty was performed in 26 patients with 9 cases of bicornuate uterus (34.6%) and 8 cases of septate uterus (30.8%). The cases diagnosed incidentally during prenatal ultrasound examination were 35.5%. Other initial symptoms were dysmenorrhea, pelvic pain and habitual abortion. Primary infertility was reported in 3 cases (2.7%) which was fewer than abortion. Primary dysmenorrhea was observed in 2 cases (1.8%). One case of PID (0.9%) and one asymptomatic case were noted. Among 241 pregnancies, there were 46.9% full term birth, 24.34% abortion, 9.5% preterm birth, and 0.83% ectopic pregnancy. Fetal presentations were 16.67% breech and 1.51% transverse lie. Cesarean section rate was 81.3%. CONCLUSIONS: Women with uterine anomaly complain symptoms such as dysmenorrhea and pelvic pain, but most are aymptomatic and diagnosed incidentally. They are frequently accompanied with urologic anomalies and complicated with obstetrical challenges such as preterm labor, habitual abortion, malpresentation, intrauterine growth retardation and uterine atony. Thus, when diagnosis of uterine anomaly is made, it is crucial to discuss sufficiently with patients about their expected prognosis on fertility and possible obstetrical outcomes and complications and to provide appropriate therapy accordingly.
