Preliminary report on Comparison of Tension-free Vaginal Tape and Transobturator Tape in the Surgical Management of Stress Urinary Incontinence / 대한산부인과학회지

OBJECTIVE: The aim of this study is to compare the efficacy of the TVT and TOT which have been widely used in the surgical management of stress urinary incontinence. METHODS: The study was carried on 22 patients with stress urinary incontinence who had operation at Seoul National University Bundang Hospital from April to December 2004. Review of medical records was done and clinical characteristics were compared according to the operation procedure. RESULTS: The TVT was done on 11 patients and TOT on 11 patients. There were no significant differences in patients' age, parity, body mass index, menopausal status, and severity of incontinence. The operation time was significantly shorter in TOT than in TVT. Complication rate and hospital stay were not significantly different between TVT and TOT. The cure rate (patients' satisfaction) was 90.9% in TVT, 100% in TOT. CONCLUSION: The TVT and TOT are both effective surgical treatment for stress urinary incontinence. The TOT is simple and time saving procedure because it can be done without cystoscope.

Live Birth After Expectant Management of Second Trimester Placental Abruption / 대한산부인과학회잡지

Prognosis of placental abruption depends on gestational age and the status of the mother and the fetus, and perinatal mortality was almost entirely attributable to prematurity. A midtrimester women with placental abruption was successfully treated by expectant management including fetal surveillance, serial ultrasonography and maternal hematologic examination, and delivered a healthy baby 11 weeks later. We suggest that expectant management may be considered as a good treatment option until fetal lung maturation is documented in preterm pregnancy with placental abruption if there is no maternal or fetal compromise.

Expression of Aquaporin-8 in Placenta of Preeclampsia / 대한산부인과학회잡지

OBJECTIVE: This study was to determine whether aquaporin-8, which plays a role as a transcellular water channel, is expressed in human placenta, and to compare the degree of its expression between preeclamptic women and normal pregnant women. METHODS: Placentas were obtained from severely preeclamptic women and normal pregnant women who were delivered babies by cesarean section before the onset of labor in the Chungbuk National University Hospital. In situ hybridization with aquaporin-8 cRNA probe was performed using paraffin-embedded tissue section. Signal of aquaporin-8 expression was observed with light microscope. RESULTS: In situ hybridization demonstrated strong expression of aquaporin-8 mRNA in the placentas of both preeclamptic women and normal pregnant women. The degree of expression was the same in both group. CONCLUSION: Aquaporin-8 in human placenta may not be related to the pathogenesis of preeclampsia.

Peritoneo-Amniotic Shunting in Isolated Fetal Ascites of Unknown Origin / 대한산부인과학회잡지

Although sporadic cases of transient fetal ascites have been described, pulmonary hypoplasia or hydrops fetalis may occur as potentially lethal complications of isolated fetal ascites. Antenatal fetal paracentesis may be useful in improving neonatal pulmonary function, however rapid accumulation of fluid after paracentesis usually required repetitive invasive procedures. We successfully treated an isolated fetal ascites with peritoneo- amniotic shunt. Under the ultrasonographic guidence, we inserted a Double-Basket Catheter into the left lower quadrant of fetal abdominal wall at the end of second trimester. Shunt remained in place until the fetus was delivered at term. The peritoneo-amniotic shunt can improve fetal outcome and avoid repeated paracentesis before delivery.
