Familial disease of the renal medulla. A study of progeny in a family with medullary cystic disease
View abstract on PubMed
Summary
This summary is machine-generated.Early signs of familial renal medulla cystic disease were identified in asymptomatic children. These included impaired urine concentration and X-ray findings similar to medullary sponge kidney.
Area Of Science
- Nephrology
- Genetics
- Pediatric Nephrology
Background
- Cystic disease of the renal medulla is typically diagnosed late, often near end-stage renal failure.
- Early diagnosis in affected families is crucial for understanding disease progression.
Observation
- Studied 12 asymptomatic children from families with known cystic disease of the renal medulla.
- Assessed renal function and performed intravenous pyelography in the children.
Findings
- Identified defects in urine concentrating ability in the children.
- Observed X-ray abnormalities on intravenous pyelography, indistinguishable from medullary sponge kidney.
- These findings suggest early manifestations of medullary cystic disease.
Implications
- A clear distinction between medullary cystic disease and medullary sponge kidney is difficult in early stages.
- Proposed "familial disease of the renal medulla" as a designation for these patients.
- Further classification should be based on evidence of disease progression.
