Medullary sponge kidney
Medullary sponge kidney is a disorder of the kidneys characterized by dilatation of the collecting tubules in one or both kidneys. Individuals with medullary sponge kidney are at increased risk for kidney stones and tract (UTI). Patients with MSK typically pass twice as many stones per year as do other stone formers without MSK. While having a low morbidity rate, as many as 10% of patients with MSK have an increased risk of morbidity associated with frequent stones and UTIs. While many patients report increased kidney pain, the source of the pain, when a UTI or blockage is not present, is unclear at this time. Renal colic is present in 55% of patients. Women with MSK experience more stones, UTIs, and than men. MSK was previously believed not to be but there is more evidence coming forth that may indicate otherwise.
