Most published reports indicate that intensified hemodialysis results in better pregnancy outcomes. Here we studied clinical characteristics and the outcomes of 28 pregnant women receiving hemodialysis. We found an association between maternal blood data and birth weight, and gestational age and outcomes. There were 18 surviving infants who were followed up for one year. In the others there were 4 spontaneous abortions, 1 stillbirth, 3 neonatal deaths and 2 deaths after birth. Analysis of blood chemistry for 20 pregnancies from 12 weeks of gestation until delivery showed that the average hemoglobin level was significantly higher in the group that successfully delivered than in the unsuccessful group. There were significant negative relationships between the blood urea nitrogen (BUN) level and the birth weight or gestational age in the latter cohort. A birth weight equal to or greater than 1500 g or a gestational age equal to or exceeding 32 weeks corresponded to BUN levels of 48-49 mg/dl or less. Whether the low BUN is the direct cause of the improved outcome remains to be examined.

Twins conceived through ART are not at an increased risk of perinatal complications. A relationship has been found between abnormal UCI and IUGR.

Leiomyomas of uterus are common disease in gynecology. It is important to differentiate leiomyoma from leiomyosarcoma at the decision of treatment methods, especially in the case of the conservative treatment for uterine leiomyoma. But the exact diagnosis of benign leiomyoma is often difficult due to the degeneration of myoma by imaging modalities including magnetic resonance imaging. Recently, whole-body positron emission tomography (PET) using F-18 fluorodeoxyglucose (FDG) has been used for a diagnosis of malignant tumors. There is a growing body of evidence for the use of FDG in differentiating malignant from benign disease. But optimal utilization in gynecology remains unclear. Our case represents increased uptake of FDG in myomatous uterus, which is pathologically confirmed benign leiomyoma by the hysterectomy. Immunohistochemical analysis of glucose transporter-1 showed positive in endometrial tissue and negative in leiomyoma. Our case indicates that myomatous uterus in premenopausal women shows the potential pitfall of a positive result of FDG-PET.
