Using amnioinfusions to treat pulmonary hypoplasia in fetuses

Serial Amnioinfusions as Regenerative Therapy for Pulmonary Hypoplasia in Fetuses With Intrauterine Renal Failure or Severe Renal Anomalies- a Feasibility Study

Phase 1 Interventional Mayo Clinic · NCT03723564

This study is testing if giving extra fluid to pregnant women with fetuses that have severe urinary problems can help improve lung development and kidney function in newborns.

What this trial studies

This clinical trial aims to evaluate the effectiveness of serial amnioinfusions in fetuses diagnosed with severe lower urinary tract obstruction (LUTO) or bilateral renal agenesis. The study will involve pregnant women with affected fetuses who will receive ultrasound-guided amnioinfusions to increase amniotic fluid levels, potentially reducing the severity of pulmonary hypoplasia. The trial will enroll a limited number of participants due to the rarity of these conditions, with a focus on monitoring outcomes over a two-year period. The goal is to assess whether this intervention can improve survival rates and renal function in newborns.

Who should consider this trial

Good fit: Ideal candidates for this study are pregnant women over 18 years old with fetuses under 26 weeks gestational age diagnosed with severe LUTO or bilateral renal agenesis.

Not a fit: Patients with associated fetal anomalies unrelated to LUTO or renal agenesis, or those with maternal conditions contraindicating surgery, may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly increase the survival chances and renal health of newborns affected by severe LUTO or bilateral renal agenesis.

How similar studies have performed: While the approach of using amnioinfusions is established, the specific application for pulmonary hypoplasia in this context is novel and has not been extensively tested.
