Multicystic dysplastic kidney in utero: changing appearance on US
Radiology
|April 1, 1986
Summary
Serial ultrasound revealed significant changes in fetal multicystic dysplastic kidneys. These dynamic changes in size and appearance suggest potential residual renal function in these cases.
Area of Science:
- Fetal medicine
- Pediatric nephrology
- Medical imaging
Background:
- Multicystic dysplastic kidney (MCDK) is a common congenital anomaly.
- The in utero behavior and potential function of MCDK are not fully understood.
Purpose of the Study:
- To analyze the serial changes in fetal MCDK using ultrasound.
- To investigate the potential for residual renal function in MCDK.
Main Methods:
- Review of serial ultrasound examinations in six cases of fetal MCDK.
- Confirmation of diagnosis through pathological or neonatal radiological examination.
Main Results:
- Dramatic changes in in utero appearance of MCDK were observed.
- All MCDK kidneys exhibited changes in size (enlargement, shrinkage, or both).
- Radiological and laboratory data suggested glomerular filtration capacity.
Conclusions:
- Fetal MCDK can exhibit significant dynamic changes in utero.
- Residual renal function, including glomerular filtration, may explain these observed changes in MCDK.
