'''Medullary sponge kidney''' is a [[congenital disorder]] of the kidneys characterized by a cystic dilatation of the collecting tubules in one or both [[kidneys]].

==Incidence==

It has been estimated to occur with a prevalence of between 1 in every 5,000-10,000 individuals in a population.

In most cases, medullary sponge kidney affects only one kidney, in which case kidney function is usually preserved and individuals may be asymptomatic.  However, these individuals are at increased risk for nephrolithiasis ([[kidney stones]]) and [[urinary tract infection]].

*Unenhanced CT scan findings may be normal or demonstrate [[nephrocalcinosis|medullary nephrocalcinosis]].
==Case Studies==
*Enhanced scans may demonstrate contrast accumulation within the papillae.
