Uterus didelphys with obstructed hemivagina and ipsilateral renal agenesis (OHVIRA) or Herlyn-Werner-Wunderlich (HWW) syndrome is a rare congenital urogenital anomaly. A 13-year-old female presented with acute abdominal pain and dysmenorrhea. Ultrasonography and magnetic resonance imaging showed uterus didelphys, hematometrocolpos, obstructed hemivagina, and right renal agenesis. Hemivaginal septal resection and anastomosis between the obstructed hemivagina and the normal vagina was tried, but it was not possible. Unilateral hysterectomy was performed. HWW syndrome may present with acute abdomen and is usually treated with vaginal septum resection and drainage of the hematometrocolpos.

Abstract Objectives: We aimed to assess placental volume and placental mean gray value in vitamin D deficiency and healthy placentas in the first trimester of pregnancy using three-dimensional (3D) ultrasonography (USG) and Virtual Organ Computer-aided Analysis (VOCAL). Methods: This prospective cross sectional study comprised 274 patients, divided into two groups according to the presence or absence of vitamin D deficiency (<20 ng/ml deficient, n = 153, >20 ng/ml not deficient, n= 121) in the first trimester of pregnancy. Placental volume and placental volumetric mean gray values were evaluated. Placental volume (cm3) was analyzed using the VOCAL imaging program and a 3D histogram was used to calculate the volumetric mean gray value (%). Results: Placental volume was significantly less in the vitamin D deficiency group (p = 0.017) Volumetric mean gray value of the placenta was significantly higher in the vitamin D deficiency group (p= 0.003). Maternal serum PAPP-A (MoM) and f-β Hcg (MoM) were significantly lower in the vitamin D deficiency group (p= 0.008, p = 0.003, respectively). In linear regression analyses, serum vitamin D concentration was significantly associated with the plasental volume (β = 0.16; p = 0.01). Conclusion: Placental configuration and development were associated with vitamin D even in the first trimester of pregnancy. To ensure healthy pregnancy outcomes, vitamin D screening applied in the early stages of pregnancy or even before pregnancy.

PurposeTo demonstrate the blood flow profiles of fetuses with cardiac anomalies at the level of Ductus venosus (DV) and Aortic isthmus (AI) to evaluate the effects of fetal cardiac anomalies on these profiles, and how these profile changes contribute to cardiac anomaly screening studies as a marker.MethodsDV and AI doppler studies were applied to 64 singleton pregnant women with fetal cardiac anomalies and 74 pregnant women with healthy fetuses. DV-PVIV (peak velocity index for veins) for DV and IFI (isthmic flow index) for AI were used.ResultsDV doppler studies in fetuses with cardiac anomalies and healthy fetuses did not show statistically significant difference. But the results of the AI doppler studies had statistically significant difference in the fetal cardiac anomaly group with the exception of cases with dilatation and regurgitation. When right-sided heart anomaly and the remaining cases were compared with the control groups, AI doppler results also showed lower IFI values.ConclusionsDV doppler studies in the second or third trimester may not be suitable as a screening test for congenital heart disease, but AI doppler studies might be considered as a supporting parameter. But further studies are needed for routine clinical use.

Objective: To compare embryo transfer (ET) technique based on catheter rotation during its withdrawal in cases with unexplained infertility in a prospective, randomized trial (NCT03097042). Methods: Two hundred intracytoplasmic sperm injection (ICSI) patients undergoing ET with cleaving or blastocyst-stage fresh embryos were randomized into 2 groups: cases with (n = 100), and without (n = 100) catheter rotation during its withdrawal. Groups were matched for age and some clinical parameters. A soft catheter was used to transfer a single embryo with catheter rotation during its withdrawal in the study group and without rotation in the control. The use of a stiff catheter or tenaculum was not needed in any case. Groups were compared in terms of cycle characteristics and clinical pregnancy rates. Results: Pregnancy rate was significantly higher in the study group (41 vs. 26%, p = 0.04). Clinical pregnancy rate was also significantly higher in the study group (39 vs. 25%, OR 1.9 [1.1–3.5], p = 0.05). On the other hand, the ongoing pregnancy rate was similar between the 2 groups (33 vs. 23%, p = 0.2). Conclusion: Catheter rotation during its withdrawal may be associated with increased pregnancy and clinical pregnancy rates; however, the difference in ongoing pregnancy rates did not reach statistical significance.

OBJECTIVES To determine the predictive value of antral follicle diameter variance within each ovary for ovarian response in cases with normal ovarian reserve tests. METHODS This is a prospective observational study. One hundred and thirty nine infertile women who underwent ART in IVF-ICSI unit of Zeynep Kamil women and childrens Health Training and research hospital between January 2017 to June 2017 were recruited. Blood samples were collected on day 2/day 3 for assessment of serum FSH and estradiol. Trans-vaginal sonography was done for antral follicle count. During antral follicle count, in order to determine antral follicle diameter variance, diameters of the largest and smallest follicles were recorded. Variance was calculated by subtracting the smallest diameter from the largest one. Following ovarian stimulation with antagonist protocol, poor response was determined in cases with total oocyte number≤3. Ovarian reserve tests and antral follicle diameter variance were utilized to predict cases with poor response in women with normal ovarian reserve. RESULTS Antral follicle diameter variance both in right (AUC=0.737, P<0.001) and left (AUC=0.651, P<0.05) ovaries significantly predicted poor ovarian response. Variance>3.5 mm was found to have 75% sensitivity to predict poor response. Basal serum FSH with estradiol levels and AFC failed to predict poor response (P>0.05). Other significant predictors for poor response were day 5 estradiol level and estradiol level at trigger day (P<0.05). In multivariate regression analysis, both AFC and antral follicle diameter variance in the right ovary were found to be significantly associated with clinical pregnancy, on the other hand peak estradiol concentration and antral follicle diameter variance in the right ovary were significantly associated with poor response. CONCLUSION Antral follicle diameter variance may be utilized to predict poor ovarian response in cases with normal ovarian reserve.

BACKGROUND Presacral teratomas are usually observed in the first two decades of life and have a 50-67% incidence of malignant transformation. Surgery is the treatment of choice. CASE REPORT Here, we report the case of 24-year-old female with chronic urinary retention after surgery for a presacral teratoma. CONCLUSION Retroperitoneal pelvic surgery may cause pelvic plexus and nerve injury, leading to permanent bladder dysfunction and urinary retention.
