Follow-up

Further Inpatient Care

  • Further inpatient care is needed only for patients with medullary sponge kidney (MSK) who have renal stones or a severe urinary tract infection (UTI).
  • Serial screening for malignancies is required in patients with medullary sponge kidney and hemihypertrophy.

Further Outpatient Care

  • Periodic screening for hematuria, bacteriuria, and kidney stones

Inpatient & Outpatient Medications

  • Medications are needed only for patients with UTIs or kidney stones.

Complications

  • Gross hematuria
  • Renal stones
  • UTIs

Prognosis

  • Medullary sponge kidney is a nonprogressive disease and has no adverse impact on renal or patient survival.

Patient Education

Miscellaneous

Medicolegal Pitfalls

  • Overtreatment of patients with medullary sponge kidney (MSK) is a pitfall.
  • Failure to discriminate medullary sponge kidney, a nonprogressive disease, from forms of cystic kidney disease that have a worse prognosis is a pitfall. Autosomal recessive polycystic kidney disease is the disease most commonly mistaken for medullary sponge kidney.
