Long-term outcome in children after antenatal intervention for obstructive uropathies

Area of Science:

• Pediatric Urology
• Fetal Surgery
• Neonatal Care

Background:

• Antenatal intervention for fetal obstructive uropathy has been performed for over a decade.
• Long-term outcomes following fetal intervention remain largely unknown.
• Assessing long-term implications of fetal intervention is crucial for guiding clinical practice.

Purpose of the Study:

• To evaluate the long-term outcomes of children who underwent vesicoamniotic shunt placement for fetal obstructive uropathy.
• To understand the implications of antenatal intervention on growth, renal function, and continence.

Main Methods:

• Retrospective review of clinical outcomes for 14 children who underwent vesicoamniotic shunt placement.
• Follow-up assessment of children who survived beyond 2 years of age.
• Analysis of diagnoses, growth parameters, renal function, and urinary continence.

Main Results:

• Of 34 patients who underwent shunt placement, 21 survived beyond 2 years. Mean follow-up was 54.3 months.
• Common diagnoses included prune belly syndrome (7) and posterior urethral valves (4).
• Significant findings included short stature (86% below 25th percentile), renal failure/transplantation (36%), renal insufficiency (21%), and varying degrees of urinary continence (50% continent).

Conclusions:

• Antenatal intervention with vesicoamniotic shunts may benefit fetuses with severe obstructive uropathy, potentially averting a fatal neonatal course.
• The outcomes achieved are comparable to less severe cases typically diagnosed postnatally.
• This intervention offers a viable option for improving long-term outcomes in selected fetal obstructive uropathy cases.
