Sonographic examination of uterine niche in non‐pregnant women: a modified Delphi procedure

Abstract

Consensus between niche experts was achieved on all items regarding ultrasonographic niche measurement.

Evaluation of uterine niche by three‐dimensional sonohysterography and volumetric quantification: techniques and scoring classification system

“…In addition to the lack of appropriately designed studies involving untreated patients as controls in the context of obstetric outcome, a significant hindrance to research in this field is the absence of a universally accepted reliable diagnostic method for the evaluation of uterine niches. Recently, by means of a Delphi consensus, a step was taken towards standardization of the nomenclature and ultrasound measurements in niche assessment. While there was no generally agreed ultrasound technique, a transvaginal approach with sagittal and transverse views for specific niche measurements was agreed upon.…”

“…While there was no generally agreed ultrasound technique, a transvaginal approach with sagittal and transverse views for specific niche measurements was agreed upon. Experts agreed that the use of contrast agents (normally gel or saline) during the scan may facilitate the assessment of a niche in which fluid is not present naturally. The role of three‐dimensional (3D) ultrasound was not a subject of this consensus, probably because it focused on basic niche assessment.…”

Outcomes after hysteroscopic repair of symptomatic isthmocele: a single center experience in Ukraine

“…Transvaginal ultrasound and sonohysterography are the most appropriate and common methods used to visualize niches [8,9]. Recently guideline for detailed uterine niche evaluation by ultrasonography in the non-pregnant woman was issued by a group of European experts [10].…”

Niche definition and guidance for detailed niche evaluation

“…Given that this approach did not take into account the possible variations concerning the morphology of niches, we developed an updated guideline on the ultrasonographic evaluation of a niche. To establish this guideline, first a modified Delphi study was executed among 15 European niche experts . These experts were selected based on their experience (number of niche evaluations per year, published articles or conference presentations concerning ultrasound and niches).…”
