Medullary sponge kidney

Medullary sponge kidney also known as Cacchi—Ricci disease is a congenital disorder of the kidneys characterized by cystic dilatation of the collecting tubules in one or both kidneys. Individuals with medullary sponge kidney are at increased risk for kidney stones and urinary tract infection UTI. While some patients report increased chronic kidney pain, the source of the pain, when a UTI or blockage is not present, is unclear at this time.

MSK was previously believed not to be hereditary but there is more evidence coming forth that may indicate otherwise. Most cases are asymptomatic or are discovered during an investigation of blood in the urine. In addition to the typical clinical phenotype of recurrent stone disease, other clinical profiles have now been recognized, that is, an indolent, almost asymptomatic MSK, and a rare form characterized by intractable pain.

Cacchi-Ricci syndrome

In recent studies, insight has been obtained on the genetic basis of this disease, supporting the hypothesis that MSK is due to a disruption at the ‘ureteric bud-metanephric mesenchyme’ interface. This explains why so many tubular defects coexist in this disease, and particularly a distal tubular acidification defect of which the highly prevalent metabolic bone disease is one very important consequence.

In addition to the typical clinical phenotype of recurrent stone disease, other clinical profiles have now been recognized, that is, an indolent, almost asymptomatic MSK, and a rare form characterized by intractable, excruciating pain. A rare, autosomal recessive form is associated with Caroli disease.

Classically, MSK is seen as hyperechoic papillae with clusters of small stones on ultrasound examination of the kidney or with an abdominal x-ray. The irregular ectatic collecting ducts are often seen in MSK, which are sometimes described as having a “paintbrush-like” appearance, are best seen on intravenous urography.

However, IV urography has been largely replaced by contrast-enhanced, high-resolution helical CT with digital reconstruction. Often, aggressive treatment is unnecessary for people with MSK disease that does not cause any symptoms asymptomatic.

In patients with low levels of mladie in the urine hypocitraturia and incomplete distal renal tubular acidosistreatment with potassium citrate helps prevent the formation of new kidney stones. Patients with the more rare form of MSK caccyi by chronic pain typically require pain management.

Non-obstructing stones in MSK can be associated with significant and chronic pain even if they’re not passing. The pain in this situation can be constant.

It is not certain what causes this pain but researchers have proposed that the small numerous stones seen in MSK may cause obstruction of the small tubules and collecting ducts in the kidney which could lead to the pain. This pain can often be debilitating and treatment is challenging. Narcotic medication even with large quantities is sometimes not adequate.
