Summary
Infants with antenatally detected multicystic dysplastic kidneys can develop late-onset kidney obstruction. Close monitoring and joint nephrouroradiology reviews are crucial for managing these urinary tract abnormalities.
Area of Science:
- Pediatric Nephrology
- Urology
- Medical Imaging
Background:
- Antenatally detected multicystic dysplastic kidneys (MCDK) are often considered nonfunctioning.
- Mild pelvic dilatation may be present in initial postnatal ultrasounds of infants with MCDK.
Purpose of the Study:
- To highlight the risk of late-onset pelviureteric obstruction in infants with antenatally detected MCDK.
- To emphasize the importance of vigilant follow-up for urinary tract abnormalities.
Main Methods:
- Case review of two infants with nonfunctioning MCDK.
- Analysis of postnatal ultrasound findings and clinical course.
Main Results:
- Both infants developed acute renal failure due to pelviureteric obstruction of the contralateral kidney at 9 and 14 months.
- Initial ultrasounds showed only mild pelvic dilatation, underscoring the potential for delayed diagnosis.
Conclusions:
- Clinicians must be aware of the possibility of late-onset obstruction in infants with antenatally detected MCDK.
- Regular review of patients with antenatal urinary tract abnormalities and equivocal findings at joint nephrouroradiology meetings is recommended.
