    Pregnancy causes kidney cavity dilation due to mechanical and hormonal factors, mimicking obstruction. Ultrasonography effectively identifies these physiological changes, distinguishing them from pathological conditions.

    Area of Science:

    • Nephrology
    • Obstetrics and Gynecology
    • Radiology

    Context:

    • Investigated physiological renal cavity changes in 128 pregnant patients.
    • Examined variations based on parity (primiparae vs. multiparae) and gestational stage.
    • Focused on patients with healthy kidneys to isolate normal pregnancy adaptations.

    Purpose:

    • To ultrasonographically characterize renal cavity alterations during pregnancy.
    • To differentiate physiological hydronephrosis from pathological obstruction.
    • To establish borderline conditions to prevent misdiagnosis of kidney abnormalities.

    Summary:

    • Ultrasonography revealed renal cavity dilatation in pregnant patients, attributed to both mechanical pressure and hormonal influences.
    • Observed ultrasonographic findings presented as signs of obstruction, necessitating careful interpretation.

  • The study successfully identified macromorphologic kidney changes during pregnancy using ultrasound.

    • Impact:

    • Provides a clearer understanding of normal renal adaptations in pregnancy.
    • Aids clinicians in accurate diagnosis by distinguishing physiological from pathological renal changes.
    • Highlights ultrasonography as a key imaging modality for monitoring kidney health during gestation.
