Summary

This study will prospectively enroll pregnant women with singleton pregnancies between 20 and 38 weeks of gestation who attend Assiut University Hospital for routine or indicated ultrasound assessment of amniotic fluid. The aim is to develop and validate a modified amniotic fluid scoring model that combines standard ultrasound measures of amniotic fluid volume with fetal bladder size and appearance. The study will compare the ability of this new scoring model to detect abnormal amniotic fluid volume against conventional ultrasound methods and will explore how fetal bladder measurements relate to amniotic fluid indices.

Detailed description

This prospective observational cohort study will be conducted in the Obstetrics and Gynecology Department at Assiut University Hospital and will enroll 70 pregnant women aged 18-45 years with singleton pregnancies between 20 and 38 weeks of gestation who are referred for routine or clinically indicated ultrasound assessment of amniotic fluid volume. The study aims to develop and validate a modified amniotic fluid scoring model that integrates standard sonographic measures of amniotic fluid volume, including the amniotic fluid index and single deepest pocket, with predefined fetal bladder parameters such as bladder presence, morphology, and longitudinal and transverse diameters measured at maximal filling. Eligible participants will undergo a standardized ultrasound examination using a high-resolution machine with a curvilinear transducer; the uterus will be systematically scanned to obtain AFI and single deepest pocket measurements, followed by a dedicated five-minute assessment of the fetal bladder to document its size, appearance, and any observed micturition events. All sonographic assessments will be performed by experienced sonographers following uniform protocols, and approximately 10 percent of examinations will be re-scanned by a second sonographer to assess interobserver reliability, with images and measurements digitally archived for blinded review.
