Recently, we experienced the conservative management of ovarian cyst torsion using transvaginal ultrasonography-guided aspiration in 39 years old woman at 9 weeks of gestational age. The patient had a 7.3 cm-sized ovarian cyst suspected torsion. The symptom was acute lower abdominal pain. Transvaginal cyst aspiration was performed twice. The symptom was resolved after the procedures. The full term delivery was done by vaginal route and the ovarian cyst disappeared.

OBJECTIVE: Several aspects of female reproduction, from folliculogenesis to corpus luteum function, are related to angiogenesis. The purpose of this study is to measure the concentrations of vascular endothelial growth factor (VEGF) in follicular fluid and serum in patients during In Vitro Fertilization-Embryo Transfer (IVF-ET) cycles. METHODS: In our prospective study, twenty-nine patients who underwent in vitro fertilization by GnRH agonist short protocol were assessed at the our infertility clinic from Aug. 2003 to July 2005. Serum VEGF and follicular fluid VEGF levels were measured in all patients at the time of oocytes retrieval. The assay technique used in this study was ELISA for serum and follicular fluid VEGF. RESULTS: Of 29 cycles, 10 cycles were pregnant (34.5%). A positive correlation existed for follicular fluid VEGF and chronologic age (r=0.428, p-value=0.021). Follicular fluid VEGF concentration showed an inverse relationship with the total number of oocytes retrieved and follicles (r=-0.493, p-value=0.007; r=-0.474, p-value=0.009). But there was no statistically significant relationship between follicular fluid VEGF concentration and serum VEGF concentration (rho=0.347). Follicular fluid VEGF concentration was significantly higher in the non-pregnant group (1468.38+/-727.33 pg/mL) compared to the pregnant group (676.48+/-542.07 pg/mL) (p-value=0.003). CONCLUSION: Our data provide some of the evidences that elevated VEGF concentrations in the follicular fluid are associated with poor conception rates in the IVF-ET cycles.

OBJECTIVE: To assess the efficacy and safety of a "mini-perc" technique of percutaneous nephrolithotomy using a 14-Fr peel-away sheath for the removal of pyelocaliceal stones, and to determine appropriate inclusion criteria. MATERIALS AND METHODS: From July 1999 to June 2002, the medical records and radiographic images of 72 patients who underwent the "mini-perc" technique of percutaneous nephrolithotomy with a 14-Fr peel-away sheath, were reviewed to determine clinical history, stone characteristics, immediate stone free rate, final stone free rate after additional procedures, complications, and hospital stay. We also analyzed the effect of the longest stone diameter, the cumulative longest diameter of stones, the cumulative stone burden, and the stone density on the immediate stone free rate using a Fisher exact test. RESULTS: The only major complication, arterial bleeding, occurred in a patient with Child A liver cirrhosis and was successfully treated by embolization with coils and a gelatin sponge. The immediate stone free rate was 80.6 %, which was significantly influenced by stone diameter but not stone density. The mean hospital stay after the procedure was 3.97 days. CONCLUSION: The "mini-perc" technique of percutaneous nephrolithotomy, which uses the 14-Fr peel-away sheath, is a safe and effective modality for treating renal calculi.

OBJECTIVE: We wanted to evaluate the therapeutic efficacy of the percutaneous balloon dilatation and large profile catheter maintenance method for the management of patients with anastomotic biliary strictures following liver transplant. MATERIALS AND METHODS: From May 1999 to June 2003, 12 patients with symptomatic benign biliary stricture complicated by liver transplantation were treated with the percutaneous balloon dilatation and large profile catheter maintenance method (1-6 months). The patients were eight males and four females, and their ages ranged from 20 to 62 years (mean age: 44 years). Ten patients underwent living donor liver transplantation and two underwent cadaveric liver transplantation. Postoperative biliary strictures occurred from two to 21 months (mean age: 18 months) after liver transplantation. RESULTS: The initial technical success rate was 92%. Patency of the bile duct was preserved for eight to 40 months (mean period: 19 months) in 10 of 12 (84%) patients. When reviewing two patients (17%), secondary balloon dilatations were needed for treating the delayed recurrence of biliary stricture. In one patient, no recurrent stenosis was seen during the further 10 months follow-up after secondary balloon dilatation. Another patient did not response to secondary balloon dilatation, and he was treated by surgery. Eleven of 12 patients (92%) showed good biliary patency for 8-40 months (mean period: 19 months) of follow-up. CONCLUSION: The percutaneous balloon dilatation and large profile catheter maintenance method is an effective therapeutic alternative for the treatment of most biliary strictures that complicate liver transplantation. It has a high success rate and it should be considered before surgery.

Accessory ovary is a rare gynecologic condition, and tumors arising in accessory ovaries are extremely rare. Accessory ovary may result from separation of migrating ovaries during embryogenesis and injuries such as inflammation and operation on normal ovary. Congenital malformations, most frequently malformations of the genitourinary organ, are seen in connection with the accessory ovary. We experienced the first case of two dermoid cysts developing in an accessory ovary located in the left infundibulopelvic ligament and another in the eutopic ovary at the same side concurrently. Here, we present this extremely rare case with a review of the literature.

Four trials of external quality assessment in diagnostic hematology were performed in 2002 with about 400 participating laboratories in Korea. We performed quality assessment for white blood cell count, hemoglobin, red blood cell count, platelet count, reticulocyte count, white cell differential count, and red blood cell morphology test. The response rate was more than 90%. The performance of quality assessment appeared to be gradually improved year by year.
