Evaluating patient harm minimization during the COVID-19-driven reduction in benign gynecological care: a nationwide claims-based longitudinal study in the Netherlands.
PloS one ·doi:10.1371/journal.pone.0345619

ObjectiveTo evaluate whether the COVID-19 pandemic influenced treatment modality, care intensity, and care setting in benign gynecological care in the Netherlands.DesignRetrospective longitudinal cohort study evaluating the effects of the C…

Hepatic Safety Considerations in the Use of Ulipristal Acetate for Symptomatic Uterine Fibroids.
Therapeutics and clinical risk management ·doi:10.2147/tcrm.s273358

IntroductionUlipristal acetate (UPA, 5 mg) demonstrated efficacy in symptom reduction for patients with symptomatic fibroids. While registration and post-marketing trials assessing UPA identified few hepatic concerns, post-marketing concern…

Quality of life 1 year after uterine artery embolization vs hysterectomy for symptomatic adenomyosis (QUESTA study)
Acta obstetricia et gynecologica Scandinavica ·doi:10.1111/aogs.15165

INTRODUCTION: Uterine artery embolization (UAE) is a less-invasive alternative for hysterectomy in therapy-resistant symptomatic adenomyosis. Comparative data are lacking. Our objective is to evaluate the non-inferiority of UAE compared wit…

Substitution of surgical care within benign gynaecology during COVID-19: waste of a good crisis? - a quantitative longitudinal study in the Netherlands
BMJ open ·doi:10.1136/bmjopen-2025-100357

OBJECTIVE: To examine the impact of the COVID-19 pandemic on the substitution of surgical procedures in benign gynaecology in the Netherlands. DESIGN: Quantitative longitudinal study evaluating the effects of the COVID-19 pandemic. SETTIN…

Microvascular flow imaging of fibroids: A prospective pilot study.
Acta obstetricia et gynecologica Scandinavica ·doi:10.1111/aogs.14914

IntroductionImaging fibroid vascularity may predict fibroid growth and aid to determine most appropriate therapy. Microvascular (MV) flow imaging is relatively new and is able to detect slow flow in small vessels. Data on feasibility, repro…

Structured hysteroscopic examination of uterine niches: a modified Delphi procedure.
Facts, views & vision in ObGyn ·doi:10.52054/fvvo.16.3.036

BackgroundUterine niches in the Caesarean section scar are seen in approximately half of women with a history of caesarean delivery. Whilst a structured ultrasound assessment of caesarean defects has been described, there is no consensus on…

Effectiveness of laparoscopic niche resection versus expectant management in patients with unexplained infertility and a large uterine caesarean scar defect (uterine niche): protocol for a randomised controlled trial (the LAPRES study).
BMJ open ·doi:10.1136/bmjopen-2022-070950

IntroductionA uterine niche is a defect at the site of the uterine caesarean scar that is associated with gynaecological symptoms and infertility. Promising results are reported in cohort studies after a laparoscopic niche resection concern…

Endometrial Angiogenesis of Abnormal Uterine Bleeding and Infertility in Patients with Uterine Fibroids-A Systematic Review.
International journal of molecular sciences ·doi:10.3390/ijms24087011

Uterine fibroids are the most common benign tumors in women, with abnormal uterine bleeding (AUB) as the main reported symptom. Additionally, an association between fibroids and infertility has been established, especially if the fibroid pr…

Reproductive outcomes after laparoscopic resection of symptomatic niches in uterine cesarean scars: Long-term follow-up on the prospective LAPNICHE study.
Acta obstetricia et gynecologica Scandinavica ·doi:10.1111/aogs.14647

IntroductionAfter incomplete healing of the uterine cesarean section scar, a niche can be observed; 24% of the women develop large niches with a residual myometrial thickness <3 mm. In these cases a laparoscopic resection is possible. The e…

Fibroid vascularisation assessed with 3D Power Doppler as predictor for fibroid related symptoms and quality of life; a pilot study.
Facts, views & vision in ObGyn ·doi:10.52054/fvvo.13.4.044

BackgroundUterine fibroids present differently, from well vascularised up to calcified, with some causing heavy menstrual bleeding (HMB).ObjectivesTo investigate the association between fibroid vascularisation and HMB, other fibroid related…

Implementation of uterine artery embolization for symptomatic fibroids in the Netherlands: an inventory and preference study.
CVIR endovascular ·doi:10.1186/s42155-019-0061-5

Background and purposeThe Dutch national guideline on heavy menstrual bleeding was updated and published in 2013. It recommended (for the first time) that uterine artery embolization (UAE) should be part of counseling of women with symptoma…
