ABSTRACT
STUDY QUESTION: Does double vitrification and thawing of an embryo compromise the chance of live birth after a single blastocyst transfer? SUMMARY ANSWER: The live birth rate (LBR) obtained after double vitrification was comparable to that obtained after single vitrification. WHAT IS KNOWN ALREADY: Double vitrification-warming (DVW) is commonly practiced to accommodate surplus viable embryos suitable for transfer, to allow retesting of inconclusively diagnosed blastocysts in preimplantation genetic testing (PGT), and to circumvent limitations associated with national policies on embryo culture in certain countries. Despite its popularity, the evidence concerning the impact of DVW practice on ART outcomes is limited and lacking credibility. This is the first thorough investigation of clinical pregnancy and LBR following DVW in the case where the first round of vitrification occurred at the zygote stage and the second round occurred at the blastocyst stage in the absence of biopsy. STUDY DESIGN SIZE DURATION: This is a retrospective observational analysis of n = 407 single blastocyst transfers whereby embryos created by IVF/ICSI were vitrified-warmed once (single vitrification-warming (SVW) n = 310) or twice (DVW, n = 97) between January 2017 and December 2021. PARTICIPANTS/MATERIALS SETTING METHODS: In the SVW group, blastocysts were vitrified on Day 5/6 and warmed on the day of embryo transfer (ET). In the DVW group, two pronuclear (2PN) zygotes were first vitrified-warmed and then re-vitrified on Day 5/6 and warmed on the day of ET. Exclusion criteria were ETs from PGT and vitrified-warmed oocyte cycles. All of the ETs were single blastocyst transfers performed at the University Hospital Zurich in Switzerland following natural or artificial endometrial preparation. MAIN RESULTS AND THE ROLE OF CHANCE: The biochemical pregnancy rate, clinical pregnancy rate (CPR), and LBR were all comparable between the DVW and SVW groups. The CPR for DVW was 44.3% and for SVW it was 42.3% (P = 0.719). The LBR for DVW was 30.9% and for SVW it was 28.7% (P = 0.675). The miscarriage rate was additionally similar between the groups: 27.9% for DVW and 32.1% for SVW groups (P = 0.765). LIMITATIONS REASONS FOR CAUTION: The study is limited by its retrospective nature. Caution should be taken concerning interpretation of these findings in cases where DVW occurs at different stages of embryo development. WIDER IMPLICATIONS OF THE FINDINGS: The result of the present study on DVW procedure provides a framework for counselling couples on their chance of clinical pregnancy per warming cycle. It additionally provides confidence and reassurance to laboratory professionals in certain countries where national policies limit embryo culture strategies making DVW inevitable.

ABSTRACT
Background: Assisted reproductive technology treatment is recommended to overcome endometriosis-associated infertility but current evidence is controversial. Endometriosis is associated with lower antral follicle count (AFC) and oocyte yield but similar clinical outcomes compared to controls. Unaffected ovarian stimulation response and embryological outcomes but lower clinical pregnancy and live birth rates and higher miscarriage rates have been reported, implying direct impact on endometrial receptivity. With evidence emerging on the benefit of frozen-warmed and blastocyst stage transfer, we investigated ART outcomes in endometriosis using homogeneous case-control groups. Methods: This is a retrospective observational case-control study including n = 66 frozen-warmed unbiopsied single blastocyst transfers of patients with endometriosis and n = 96 of women exhibiting idiopathic sterility. All frozen-warmed transfers followed artificial endometrial preparation. Results: In control women, the mean number of oocytes recovered at oocyte pick up was higher compared to women with endometriosis (15.3 ± 7.1 vs. 12.7 ± 5.2, p = 0.025) but oocyte maturation index (mature oocytes/total oocytes at oocyte pick up) was significantly higher for endometriosis (48.2% vs. 34.0%, p = 0.005). The same was shown for the subgroup of 44 endometriosis patients after endometrioma surgery when compared with controls (49.1% vs. 34.0%, p = 0.014). Clinical pregnancy rate was not higher in endometriosis but was close to significance (47.0% vs. 32.3%, p = 0.059) while live birth rate was comparable (27.3% vs. 32.3%, p = 0.746). Miscarriage rate was higher in the endometriosis group (19.7% vs. 7.3%, p = 0.018). A significantly higher AFC was observed in the control group in comparison with the endometriosis group (16.3 ± 7.6 vs. 13.4 ± 7.0, p = 0.014). Live birth rate did not differ when comparing all endometriosis cases (p = 0.746), ASRM Stage I/II and Stage III/IV (p = 0.348 and p = 0.888) with the control group but the overall pregnancy rate was higher in ASRM Stage I/II (p = 0.034) and miscarriage rate was higher in ASRM Stage III/IV (p = 0.030) versus control. Conclusion: Blastocyst transfers in women with endometriosis originate from cycles with lower AFC but higher share of mature oocytes than in control women, suggesting that endometriosis might impair ovarian reserve but not stimulation response. A higher miscarriage rate, independent of blastocyst quality may be attributed to an impact of endometriosis on the endometrium beyond the timing of implantation.
ABSTRACT
BACKGROUND: Prolonged amenorrhoea occurs as a consequence of functional hypothalamic amenorrhoea (FHA) which is most often induced by weight loss, vigorous exercise or emotional stress. Unfortunately, removal of these triggers does not always result in the return of menses. The prevalence and conditions underlying the timing of return of menses vary strongly and some women report amenorrhoea several years after having achieved and maintained normal weight and/or energy balance. A better understanding of these factors would also allow improved counselling in the context of infertility. Although BMI, percentage body fat and hormonal parameters are known to be involved in the initiation of the menstrual cycle, their role in the physiology of return of menses is currently poorly understood. We summarise here the current knowledge on the epidemiology and physiology of return of menses. OBJECTIVE AND RATIONALE: The aim of this review was to provide an overview of (i) factors determining the recovery of menses and its timing, (ii) how such factors may exert their physiological effects and (iii) whether there are useful therapeutic options to induce recovery. SEARCH METHODS: We searched articles published in English, French or German language containing keywords related to return of menses after FHA published in PubMed between 1966 and February 2020. Manuscripts reporting data on either the epidemiology or the physiology of recovery of menses were included and bibliographies were reviewed for further relevant literature. The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) criteria served to assess quality of observational studies. OUTCOMES: Few studies investigate return of menses and most of them have serious qualitative and methodological limitations. These include (i) the lack of precise definitions for FHA or resumption of menses, (ii) the use of short observation periods with unsatisfactory descriptions and (iii) the inclusion of poorly characterised small study groups. The comparison of studies is further hampered by very inhomogeneous study designs. Consequently, the exact prevalence of resumption of menses after FHA is unknown. Also, the timepoint of return of menses varies strongly and reliable prediction models are lacking. While weight, body fat and energy availability are associated with the return of menses, psychological factors also have a strong impact on the menstrual cycle and on behaviour known to increase the risk of FHA. Drug therapies with metreleptin or naltrexone might represent further opportunities to increase the chances of return of menses, but these require further evaluation. WIDER IMPLICATIONS: Although knowledge on the physiology of return of menses is presently rudimentary, the available data indicate the importance of BMI/weight (gain), energy balance and mental health. The physiological processes and genetics underlying the impact of these factors on the return of menses require further research. Larger prospective studies are necessary to identify clinical parameters for accurate prediction of return of menses as well as reliable therapeutic options.

MOTIVATION: Model-based approaches to safety and efficacy assessment of pharmacological drugs, treatment strategies or medical devices (In Silico Clinical Trial, ISCT) aim to decrease time and cost for the needed experimentations, reduce animal and human testing, and enable precision medicine. Unfortunately, in presence of non-identifiable models (e.g. reaction networks), parameter estimation is not enough to generate complete populations of Virtual Patients (VPs), i.e. populations guaranteed to show the entire spectrum of model behaviours (phenotypes), thus ensuring representativeness of the trial. RESULTS: We present methods and software based on global search driven by statistical model checking that, starting from a (non-identifiable) quantitative model of the human physiology (plus drugs PK/PD) and suitable biological and medical knowledge elicited from experts, compute a population of VPs whose behaviours are representative of the whole spectrum of phenotypes entailed by the model (completeness) and pairwise distinguishable according to user-provided criteria. This enables full granularity control on the size of the population to employ in an ISCT, guaranteeing representativeness while avoiding over-representation of behaviours. We proved the effectiveness of our algorithm on a non-identifiable ODE-based model of the female Hypothalamic-Pituitary-Gonadal axis, by generating a population of 4 830 264 VPs stratified into 7 levels (at different granularity of behaviours), and assessed its representativeness against 86 retrospective health records from Pfizer, Hannover Medical School and University Hospital of Lausanne. The datasets are respectively covered by our VPs within Average Normalized Mean Absolute Error of 15%, 20% and 35% (90% of the latter dataset is covered within 20% error).

ABSTRACT
STUDY QUESTION: Can a core outcome set to standardize outcome selection, collection, and reporting across future infertility research be developed? SUMMARY ANSWER: A minimum data set, known as a core outcome set, has been developed for randomized controlled trials (RCT) and systematic reviews evaluating potential treatments for infertility. WHAT IS KNOWN ALREADY: Complex issues, including a failure to consider the perspectives of people with fertility problems when selecting outcomes, variations in outcome definitions, and the selective reporting of outcomes on the basis of statistical analysis, make the results of infertility research difficult to interpret. STUDY DESIGN, SIZE, DURATION: A three-round Delphi survey (372 participants from 41 countries) and consensus development workshop (30 participants from 27 countries). PARTICIPANTS/MATERIALS, SETTING, METHODS: Healthcare professionals, researchers, and people with fertility problems were brought together in an open and transparent process using formal consensus science methods. MAIN RESULTS AND THE ROLE OF CHANCE: The core outcome set consists of: viable intrauterine pregnancy confirmed by ultrasound (accounting for singleton, twin, and higher multiple pregnancy); pregnancy loss (accounting for ectopic pregnancy, miscarriage, stillbirth, and termination of pregnancy); live birth; gestational age at delivery; birthweight; neonatal mortality; and major congenital anomaly. Time to pregnancy leading to live birth should be reported when applicable. LIMITATIONS, REASONS FOR CAUTION: We used consensus development methods which have inherent limitations, including the representativeness of the participant sample, Delphi survey attrition, and an arbitrary consensus threshold. WIDER IMPLICATIONS OF THE FINDINGS: Embedding the core outcome set within RCTs and systematic reviews should ensure the comprehensive selection, collection, and reporting of core outcomes. Research funding bodies, the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) statement, and over 80 specialty journals, including the Cochrane Gynaecology and Fertility Group, Ferility and Sterility, and Human Reproduction, have committed to implementing this core outcome set.

STUDY QUESTION: Does follicular flushing increase the number of mature oocytes in monofollicular IVF? SUMMARY ANSWER: Follicular flushing increases the number of mature oocytes in monofollicular IVF. WHAT IS KNOWN ALREADY: Flushing increases neither the oocyte yield nor the pregnancy rate in polyfollicular IVF or in poor responder patients. In monofollicular IVF, the effect of flushing has so far been addressed by two studies: (i) a prospective study with minimal stimulation IVF demonstrated an increased oocyte yield, and (ii) a retrospective study with natural cycle (NC)-IVF showed an increased oocyte yield and an increased transfer rate. STUDY DESIGN, SIZE, DURATION: Randomized controlled trial including 164 women who were randomized for either aspiration with or without flushing from 2016 to 2019. PARTICIPANTS/MATERIALS, SETTING, METHODS: Infertile women 18-42 years of age with an indication for IVF treatment at a university-based infertility unit. Women undergoing monofollicular IVF were randomized to either follicular aspiration only or follicular aspiration directly followed by five follicular flushes at a 1:1 ratio. The intervention was done without anaesthesia, using a gauge 19 single-lumen needle. Flushing volume was calculated (sphere formula) based on the size of the follicle. MAIN RESULTS AND THE ROLE OF CHANCE: A total of 164 women were included; 81 were allocated to 'aspiration only' and 83 to additional 'flushing'. Primary analysis was based on the intention-to-treat: oocyte yield, defined as the collected mature oocyte rate, was higher (n = 64/83, 77.1%) in the flushing group compared to the aspiration only group (n = 48/81, 59.3%, adjusted risk difference (RD): 18.2% (95% CI 3.9-31.7%), P-value = 0.02). In the flushing group, most oocytes were retrieved within the first three flushes (63/83, 75.8%). Fertilization rate was higher in the flushing group (n = 53/83, 63.9% vs n = 38/81, 46.9%; adjusted RD: 16.8% (96% CI 1.5-31.4%), P = 0.045). Transfer rate was also higher in the flushing group (n = 52/83, 62.7% vs n = 38/81, 46.9%; RD: 15.71 (95% CI 0.3-30.3%)), but the difference was not significant (P = 0.06). The clinical pregnancy rate n = 9/83 versus n = 9/81 (RD: -0.3% (95% CI -9.9% to 9.5%)) and live birth rate n = 7/83 versus n = 8/81 (RD: -1.5% (95% CI -10.4% to 7.1%)) were not significantly different between the flushing and the aspiration group. The median duration of the intervention was significantly longer with flushing (2.38 min; quartiles 2.0, 2.7) versus aspiration only (0.43 min; quartiles 0.3, 0.5) (P < 0.01). There was no significant difference in the mean (±SD) visual analogue scales pain score between the follicular flushing (3.4 ± 1.8) and the aspiration group (3.1 ± 1.89). LIMITATIONS, REASONS FOR CAUTION: Blinding of the procedure was not possible. WIDER IMPLICATIONS OF THE FINDINGS: Our study proved that flushing of single follicles in NC-IVF increases the oocyte yield. In contrast to polyfollicular IVF flushing seems to be beneficial in a monofollicular setting if the technique used in our study (single-lumen needle, 5 flushings with flushing volume adaptation) is applied. STUDY FUNDING/COMPETING INTEREST(S): The study was funded by the financial sources of the division and in part by a research grant provided by NMS Biomedical SA, Switzerland. The company did not have any roles in design or conduct of the study or in the preparation of the manuscript. The authors have no other conflicts of interest.

Overweight and obesity are major risk factors for a number of chronic diseases, including diabetes, cardiovascular diseases, and cancer. Obesity rates are on the rise worldwide with women more frequently affected than men. Hedonic responses to food seem to play a key role in obesity, but the exact mechanisms and relationships are still poorly understood. In this study, we investigate the perceived pleasantness of food rewards in relation to satiety and calories consumed during an ad libitum meal in women. Using functional magnetic resonance imaging (fMRI) and a milkshake consumption task, we studied how experienced food values are encoded in women with healthy weight, overweight or obesity. Participants rated the pleasantness and intensity of high and low caloric milkshakes in the fMRI scanner during both the fasted and fed states. We found differences in the neural responses and experienced pleasantness of high and low caloric milkshakes depending on satiety and Body Mass Index (BMI). Women with both high ad libitum consumption levels and high BMI reported greater experienced pleasantness for milkshakes. In contrast, among women with low ad libitum consumption levels, greater BMI was associated with less experienced pleasantness. At the neural level, satiety affected women with obesity to a lesser degree than women with healthy weight. Thus, having obesity was associated with altered relationships between food consumption and the hedonic responses to food rewards as well as reduced satiety effects in women.

STUDY QUESTION: Is maltreatment during childhood (MC), e.g. sexual abuse, physical abuse, emotional abuse and neglect, associated with diagnosis of endometriosis? SUMMARY ANSWER: Childhood sexual abuse, emotional abuse/neglect and inconsistency experiences were associated with the diagnosis of endometriosis while no such association was found for physical abuse/neglect and other forms of maltreatment. WHAT IS KNOWN ALREADY: Symptoms of endometriosis such as chronic pelvic pain, fatigue and depression, are correlated with MC, as are immune reactions linked to endometriosis. These factors support a case for a potential role of MC in the development of endometriosis. STUDY DESIGN, SIZE, DURATION: The study was designed as a multicentre retrospective case-control study. Women with a diagnosis of endometriosis were matched to control women from the same clinic/doctor's office with regard to age (±3 years) and ethnic background. A total of 421 matched pairs were included in the study. PARTICIPANTS/MATERIALS, SETTING, METHODS: Women with endometriosis and control women were recruited in university hospitals, district hospitals, and doctors' offices in Germany, Switzerland and Austria. A German-language version of the Childhood Trauma Questionnaire (CTQ) was used to evaluate MC. Diagnosis of endometriosis was confirmed histologically and classified according to ASRM criteria. MAIN RESULTS AND THE ROLE OF CHANCE: Women with endometriosis reported significantly more often than control women a history of sexual abuse (20%/14%, P = 0.0197), emotional abuse (44%/28%, P < 0.0001), emotional neglect (50%/42%, P = 0.0123) and inconsistency experiences (53%/41%, P = 0.0007). No statistically significant differences could be demonstrated for physical abuse/neglect (31%/26%, P = 0.1738). Combinations of different abuse/neglect experiences were described significantly more often in women with endometriosis. Frequencies of other MC, i.e. violence against the mother (8%/7%, P = 0.8222), drug abuse in the family (5%/3%, P = 0.0943), mentally handicapped family members (1%/1%, P = 0.7271), suicidal intentions in the family (6%/4%, P = 0.2879) and family members in prison (1%/1%, P = 0.1597) were not statistically different in women with endometriosis and control women. LIMITATIONS, REASONS FOR CAUTION: Some control women might present asymptomatic endometriosis, which would lead to underestimation of our findings. The exclusion of pregnant women may have biased the results. Statistical power for sub-analyses of physical abuse/neglect and sexual abuse was limited. WIDER IMPLICATIONS OF THE FINDINGS: A link to MC needs to be considered in women with endometriosis. As there are effective strategies to avoid long-term consequences of MC, healthcare professionals should inquire about such experiences in order to be able to provide treatment for the consequences as early as possible.

Current therapeutic options allow successful treatment in only part of the women presenting with endometriosis. Pain, fatigue/exhaustion, intensive and repeated therapies as well as a concentration on the disease lead to a variety of consequences concerning education/ profession, body perception, self-esteem, partnership/social contacts, sexuality and psychic well-being. Difficulties in becoming pregnant represent a further central problem in dealing with endometriosis. Therefore, biopsychosocial aspects should be integrated into current somatically oriented models of medical support.

BACKGROUND: Childhood sexual abuse can have several negative consequences on pregnancy, birth, and the early neonatal period. However, most obstetricians are not aware if their patients have a history of childhood sexual abuse. We therefore investigated childhood sexual abuse experiences in 226 women three to eight months after delivery of a healthy child. METHODS: 415 women were approached to answer a self-administered questionnaire including obstetrical questions and questions focusing on abuse experiences. 320 women agreed to participate, 226 (69.1% of the women fulfilling inclusion criteria) of which returned a completed questionnaire. Sexual abuse was explored using a modified version of a questionnaire developed by Wyatt. The complete questionnaire was designed in cooperation with the German "Frauennotruf", a society providing care for victims of sexual abuse. RESULTS: The prevalence of childhood sexual abuse was a minimum of 11.5% and a maximum of 14.6% if women who were not sure about such experiences during their childhood were included. Another 1.3% of the women had experienced sexual abuse as an adult. Lifetime sexual abuse prevalence was 12.8% and 15.9%, respectively. Of the women with an experience of childhood sexual abuse, 42.3% mentioned an ongoing abuse situation for at least six months. CONCLUSIONS: As approximately every 9th woman presenting for obstetrical care has experienced childhood sexual abuse, and as those experiences may have a negative impact on fetal and maternal well-being, adequate counseling models should be offered to victims of sexual abuse.

BACKGROUND: Parental care giving, divorce and death are associated with physical health as an adult. AIM: To investigate whether the structure of the nuclear family during childhood shows any correlation with the development of hypertensive diseases in pregnancy as an adult. STUDY DESIGN: Self-administered questionnaires were sent to 2600 women with hypertensive diseases in pregnancy and to 1484 controls. SUBJECTS: After confirmation of the diagnosis data from 842 patients and 623 control women were evaluated. OUTCOME MEASURES: Type, number and involvement of different caregivers, parental separation, parental death. RESULTS: In both groups parental separation and parental death were found equally often. In all age groups during childhood fathers were involved significantly less often in care giving when women with hypertensive disorders in pregnancy were compared to control women (1st-3rd year 23.4%/17%, <0.0001; 4th-10th year 25.7%/19.3%, <0.0001; 11th-18th year 30.1%/23.9%, <0.0001). The total number of caregivers involved was significantly higher in patients. CONCLUSIONS: The quality of parental care giving, i.e. the involvement of fathers and the total number of caregivers correlate with the risk to develop HDP. Further research is needed to specify underlying mechanisms and the relevant factors of the parent-child relationship.

The prune-belly syndrome (PBS) consists of abdominal wall distention with deficiency of the abdominal wall musculature, urinary tract abnormalities, and cryptorchidism. The impaired drainage of the bladder leads to oligohydramnios and pulmonary hypoplasia. We present 4 cases of PBS diagnosed by prenatal sonography. In 2 cases, vesicoamniotic shunt therapy was not indicated because of a poor prognosis based on sonographic and laboratory findings; the pregnancies were terminated. In another case, treatment was not performed because of a twin pregnancy, and the neonate with PBS died the day of delivery by cesarean section at 31 weeks' menstrual age. In the other case, vesicoamniotic shunt therapy was successfully performed, and a healthy child was delivered. Several conditions must be met for vesicoamniotic shunt therapy to have a good chance of success: the karyotype must be normal, other malformations must be excluded by careful sonographic examination, and renal function must be normal, as determined by serial analyses of fetal urine. Generally, the shunt should be inserted as early as possible.

BACKGROUND: Although Hyperemesis gravidarum (HG) is still a disease of unknown aetiology psychosocial aspects are involved in the genesis of this disease. MATERIALS AND METHODS: Based on experiences in our department and on actual literature psychosocial aspects and therapeutic approaches of HG are presented. RESULTS: Predisposing factors of HG are stress, inadequate information about pregnancy or delivery and problems in the marital relationship. Feelings of ambivalence towards pregnancy, a distorted perception of reality, the unconscious refusing of a wanted child and the worry about a relation between nutrition of the foetus and the HG have influence on the development of the HG. The role of the social context, especially the mother, of expectations towards vomiting and of secondary gain in the genesis and the evaluation of HG is explained. Therapeutical approaches beside the known somatic therapies are acupuncture, the electric stimulation of the N. vestibularis and different methods of psychotherapy, which can include the partner or other persons from the social context. In some cases an intensified therapy under in-patient conditions can improve therapeutic results. DISCUSSION: Psychosocial factors are involved not only in the genesis of HG, but also in the duration and intensity of symptoms as well as in the resistance especially, towards isolated somatic therapeutical approaches. CONCLUSIONS: When psychosocial factors are taken into account in the search for a cause and the treatment of HG results of treatment are more successful and persist over a longer time.

PURPOSE: Lethal osteochondrodysplasias show an abnormal maturation and a disturbed growth of cartilage and bones. They represent a heterogeneous group of rare genetic diseases. Their incidence is 1 to 3 in 10,000 births. MATERIAL AND METHODS: We report altogether 5 cases: two of thanatophoric dysplasia, one of achondrogenesis type II and two cases of the rare fibrochondrogenesis. The differential diagnosis in respect to ultrasonographic, morphologic, radiographic and histopathologic criteria of the most common of these diseases are discussed together with a review of the literature. RESULTS: On the basis of the ultrasound finding of the short-rib-syndrome, it is possible to differentiate between viable and lethal osteochondrodysplasias at 19 to 22 weeks of gestation. The short-rin-syndrome leads to pulmonary hypoplasia. CONCLUSIONS: It is essential to obtain an exact diagnosis postnatally by radiographic and histopathological examinations to counsel the parents concerning the risk of recurrency. The risk in this heterogeneous group of genetic diseases ranges between less than 1% up to 50% depending on the final diagnosis. Our two cases of fibrochondrogenesis in a consanguineous couple strongly suggest an autosomal recessive inheritance in this disease.

In a collective of 80 premenopausal women presenting with a total of 83 adnexal masses we tried to find out whether there is any influence on Doppler results by the phase of menstrual cycle. All measurements were performed with a 5.0 MHz transvaginal probe of an Acuson 125 Xp10 between April 1993 and September 1998. In 39 tumours measurements were performed during the follicular phase, in 44 tumours during the luteal phase. Histopathological evaluation showed 72 benign and 11 malignant adnexal masses. A cut-off of 0.69 for PI and 0.45 for RI was used to differentiate preoperatively between benign and malignant masses. In the follicular phase was a sensitivity of 40% and a specificity of 76.5% for RI. Referring values for PI were 60% and 70.6%. In the luteal phase RI led to a sensitivity of 83.3% and a specificity of 71.1%. Regarding PI a sensitivity of 100% and a specificity of 68.4% was achieved. There was no statistically significant difference when sensitivity and specificity for both parameters were compared in the two phases of menstrual cycle. These results are in contrast to the hypothesis that Corpora lutea are responsible for a higher degree of false positive results during the luteal phase. We therefore think that there is no advantage in performing Doppler measurements strictly during the follicular phase.

The Prune Belly Syndrome combines dilation of the bladder and a laxity of the abdominal wall, and is of unknown etiology. The sequelae are a pulmonary hypoplasia and a deterioration of the kidney function, which determine prognosis. Via early ultrasound diagnosis, intrauterine application of a vesico-amniotic shunt can be performed and can improve survival rates. Inclusion criteria for a vesicoamniotic shunt are a lack of further sonomorphological abnormalities, a lack of an indication for an alteration of the kidney function by ultrasound or laboratory tests, and a normal karyotype.

In 265 adnexal masses results of conventional transvaginal sonography and coloured doppler sonography were compared with histopathological results. Statistical evaluation was based on lowest PI and RI as well as highest peak systolic velocity from signals derived of all detectable tumour vessels. Cut-off values from actual literature and cut-off values established in Aachen (PI < 0.69, RI < 0.45) were used. Histopathologic evaluation showed 210 (79.2%) benign and 55 (20.8%) malignant ovarian tumours. A cut-off at < 0.69 for the PI led to a sensitivity of 79.6% and a specificity of 58.2%. For RI sensitivity was 66.7% and specificity was 68.7% at a cut-off at < 0.45. The sonomorphologic evaluation following a scale published by Sassone et al. [20] had a sensitivity of 85.2% and a specificity of 67.1%. There was no statistical significant difference between mean values for peak systolic velocity in benign and malignant tumours. The exclusive evaluation with Doppler sonography leads to a high percentage of misdiagnosis. A combination with sonomorphologic evaluation does not lead to an important improvement of preoperative diagnosis as there is a bright overlap between benign and malignant tumours. In contrast Doppler sonography might add important information in the preoperative evaluation of early ovarian cancer.
