Objectives: After studying the article entitled “Medullary Sponge Kidney and Medullary Nephrocalcinosis,” you will be able to:
Determine the sonographic characteristics of medullary sponge kidney
Explain the role of medullary sponge kidney in medullary nephrocalcinosis
Demonstrate the difference in the sonographic appearance of medullary sponge kidney versus medullary nephrocalcinosis
Typically, the kidney in a patient with medullary sponge kidney will be Enlarged Normal size Hypotrophic Atrophic
Medullary sponge kidney typically occurs in patients in their Teenage years 20s to 30 years 30s and 40s to 50 years 50s and 60s to 70 years
Medullary sponge kidney is a condition characterized by Obstruction of the ureter Medullary wasting Dilation of the major calyces Dilation of the collecting tubules
Medullary sponge kidney and medullary nephrocalcinosis Rarely coexist Frequently coexist Always coexist Are different terms for the same disease
Medullary sponge kidney is likely to present Isolated to the renal pelvis Focally Diffusely Either focally or diffusely
The sonographic appearance of medullary sponge kidney alone is typically Prominent hypoechoic calyces Hyperechoic calyces Diffuse medullary hyperechogenicity Focal medullary hyperechogenicity
The initial clinical result of medullary sponge kidney is Urinary stasis Calcium deposits in the collecting tubules Kidney stones Hematuria
Nephrocalcinosis most commonly occurs in the Renal cortex Renal medulla Major calyces Renal pelvis
The most common medical condition associated with medullary nephrocalcinosis is Hyperthyroidism Papillary necrosis Hyperparathyroidism Medullary sponge kidney
The sonographic appearance of medullary sponge kidney with medullary nephrocalcinosis is typically A dilated renal pelvis Renal cysts containing hypoechoic debris Echogenic renal pyramids Cortical hypoechogenicity
