Abstract:
The term medullary sponge kidney refers as a renal parenchymal malformation characterized by cystic dilatation of the collecting ducts. Although medullary sponge kidney is a congenital disease, it is rarely identified in childhood and is usually discovered in adulthood. We report a child with bilateral medullary sponge kidney who, in addition to typical urographic findings, presented an unfavorable evolution that ended in renal chronic insufficiency. This outlook is uncommon and is described in only 10% of affected subjects.
Insights
Medullary sponge kidney is a rare congenital condition. This case highlights an unusual childhood presentation with severe progression to chronic kidney disease, a rare outcome.
Area of Science:
- Pediatric Nephrology
- Urology
- Medical Genetics
Background:
- Medullary sponge kidney (MSK) is a congenital renal malformation.
- Characterized by cystic dilatation of the renal collecting ducts.
- Typically diagnosed in adulthood, rarely in childhood.
Observation:
- A pediatric case of bilateral medullary sponge kidney is presented.
- The patient exhibited typical urographic findings associated with MSK.
- An uncommon, unfavorable clinical evolution was observed.
Findings:
- The child developed progressive chronic renal insufficiency.
- This severe outcome is infrequent, occurring in only 10% of MSK cases.
- Highlights the potential for severe disease progression even in pediatric patients.
Implications:
- Emphasizes the importance of long-term monitoring for pediatric MSK patients.
- Suggests genetic or environmental factors may influence MSK progression.
- Underscores the need for early identification and management strategies to prevent renal failure.
