medullary sponge kidney/proteinuria

We report a patient with medullary sponge kidney (MSK) who presented with hematuria and nephrotic-range proteinuria. Renal biopsy revealed a diagnosis of renal AA amyloidosis. No secondary factors contributing to renal amyloidosis were demonstrated. To the best of our knowledge, this is the first

BACKGROUND Medullary sponge kidney (MSK) is characterized by cystic dilatation of the inner medullary collecting ducts, which causes the kidneys to resemble a sponge. METHODS Although distal renal tubular acidosis (dRTA) is commonly observed in patients with MSK, we report a 5-year-old girl with MSK

Hemihypertrophy is a clinical condition defined as an asymmetric enlargement of one side of the body. Inguinal hernias, renal cysts, cryptorchidism, ectasias of collecting tubes, medullary sponge kidney and horse-shoe kidney are examples of abnormalities associated with hemihypertrophy that have

Nephrocalcinosis (NC) is a renal disease characterized by deposition of calcium salts into the renal medulla. There are several causes, organic, iatrogenic, hereditary and sometimes related to extrarenal diseases. We studied 34 children affected by NC, 21 M and 13 F (average age at diagnosis 7.8

Significant glomerular changes occur in a substantial number of renal cadaver allotransplants. Transplant glomerulopathy and recurrent glomerulonephritis account for most of the lesions whereas the development of de novo glomerulonephritis is a rare event. Only a few cases of membranous
