Medullary sponge kidney (MSK) disease, a rare kidney malformation featuring recurrent renal stones and nephrocalcinosis, continues to be diagnosed using expensive and time-consuming clinical/instrumental tests (mainly urography). Currently, no molecular diagnostic biomarkers are available. To identify such we employed a proteomic-based research strategy utilizing urine from 22 patients with MSK and 22 patients affected by idiopathic calcium nephrolithiasis (ICN) as controls. Notably, two patients with ICN presented cysts...

Medullary sponge kidney (MSK) is a congenital renal disorder. Its association with several developmental abnormalities in other organs hints at the likelihood of some shared step(s) in the embryogenesis of the kidney and other organs. It has been suggested that the REarranged during Transfection (RET) proto-oncogene and the Glial cell line-Derived Neurotrophic Factor (GDNF) gene are defective in patients with MSK, and both RET and GDNF are known to have a role in the development of the central nervous system, heart, and craniofacial skeleton...

INTRODUCTION: The mechanism of kidney stone formation is not well understood. To better understand the pathophysiology for specific kidney stone compositions and systemic diseases associated with kidney stones, endoscopic papillary mapping studies with concurrent biopsies have been conducted. This review will summarize the findings of these studies and proposed mechanisms for thirteen disease processes associated with kidney stones. EVIDENCE ACQUISITION: A review of the literature was performed identifying thirteen studies that endoscopically mapped and biopsied renal papillae of different stone formers...

Diseases of the kidney often have their names shortened, creating an arcane set of acronyms which can be confusing to both radiologists and clinicians. This review of renal pathology aims to explain some of the most commonly used acronyms within the field. For each entity, a summary of the clinical features, pathophysiology, and radiological findings is included to aid in the understanding and differentiation of these entities. Discussed topics include acute cortical necrosis, autosomal dominant polycystic kidney disease, angiomyolipoma, autosomal recessive polycystic kidney disease, acute tubular necrosis, localized cystic renal disease, multicystic dysplastic kidney, multilocular cystic nephroma, multilocular cystic renal cell carcinoma, medullary sponge kidney, paroxysmal nocturnal hemoglobinuria, renal papillary necrosis, transitional cell carcinoma, and xanthogranulomatous pyelonephritis...

PURPOSE: Nephrocalcinosis is commonly present in primary hyperparathyroidism, distal renal tubular acidosis and medullary sponge kidney disease. To our knowledge it has not been studied in patients with calcium phosphate stones who do not have systemic disease. MATERIALS AND METHODS: We studied patients undergoing percutaneous nephrolithotomy who had calcium phosphate or calcium oxalate stones and did not have hyperparathyroidism, distal renal tubular acidosis or medullary sponge kidney disease...

Medullary nephrocalcinosis is a hallmark of medullary sponge kidney (MSK). We had the opportunity to study a spontaneous calcification process in vitro by utilizing the renal cells of a patient with MSK who was heterozygous for the c.-27 + 18G>A variant in the GDNF gene encoding glial cell-derived neurotrophic factor. The cells were obtained by collagenase digestion of papillary tissues from the MSK patient and from two patients who had no MSK or nephrocalcinosis. These cells were typed by immunocytochemistry, and the presence of mineral deposits was studied using von Kossa staining, scanning electron microscopy analysis and an ALP assay...

Medullary sponge kidney (MSK) is associated with recurrent stone formation, but the clinical phenotype is unclear because patients with other disorders may be incorrectly labeled MSK. We studied 12 patients with histologic findings pathognomonic of MSK. All patients had an endoscopically recognizable pattern of papillary malformation, which may be segmental or diffuse. Affected papillae are enlarged and billowy, due to markedly enlarged inner medullary collecting ducts (IMCD), which contain small, mobile ductal stones...

BACKGROUND: Percutaneous nephrolithotomy (PCNL) was mostly performed with fluoroscopy and/or ultrasonography. The safety and feasibility of PCNL performed totally under ultrasound are not clearly defined. Therefore, we introduce the 9-year experience of 8 025 ultrasound guided PCNL procedures from multiple centers in China performed by the same surgeon, to evaluate the feasibility and security of this technique. METHODS: From September 2004 to August 2013, 8 025 cases, 4 398 males (54...

PURPOSE: Calcium stones represent 85% to 90% of all urinary calculi, including various crystalline compositions and etiological conditions. Calcium phosphate accounts for 10% to 15% of cases. These stones are mainly related to 3 groups of risk factors, including calcium or phosphate metabolism disturbance, renal acidification defects and urinary tract infection. Identifying the stone etiology often requires extensive metabolic evaluation. We assessed whether stone analysis including morphological typing in addition to stone composition could be a valuable help for diagnosis...

INTRODUCTION: Nephrocalcinosis consists of the deposition of calcium salts in the renal parenchyma and is considered the mixed form when it involves the renal cortex and medulla. The main etiological agents of this condition are primary hyperparathyroidism, renal tubular acidosis, medullary sponge kidney, hyperoxaluria and taking certain drugs. These factors can lead to hypercalcemia and/or hypercalciuria, which can give rise to nephrocalcinosis. CASE PRESENTATIONS: Patient 1 was a 48-year-old Caucasian woman with a history of bilateral nephrocalcinosis causing chronic kidney failure...

The term hemihyperplasia refers to an enlargement of body parts beyond the normal asymmetry. Hemihyperplasia can be isolated or associated with various well-described malformation syndromes. Medullary sponge kidney (MSK) has been described with isolated and syndromic hemihyperplasia; the actual prevalence is not known The hemi hypertrophy can be so subtle that it may be easily overlooked. MSK need not be limited to the side of hemihyperplasia - most often it is bilateral. Around 33 cases has been reported from different parts of the world of which 15 cases are isolated hemi hyperplasia (IHH), the remaining occurring in the context of various malformation syndromes So far only one case has been reported from India...

REVIEW
Jocelyn C Leung
Genetic disorders of the kidney include cystic diseases, metabolic diseases and immune glomerulonephritis. Cystic diseases include autosomal dominant and recessive polycystic kidney disease (ADPKD, ARPKD, respectively). Neonates with enlarged, cystic kidneys should be evaluated for PKD. Patients with ADPKD have cysts and renal enlargement. Most patients present with hypertension, hematuria or flank pain; the most common extrarenal manifestation is polycystic liver disease. Oligohydramnios, bilaterally enlarged kidneys and decreased urine are featured in utero in ARPKD...

The medullary sponge kidney is a malformation characterized by Bellini ducts' ectasias and often by nephrocalcinosis. Scientific literature demonstrates and emphasizes how the Rx-urography plays a primary role to achieve diagnostic certainty in cases of suspected MSK. Pathognomonic urographic aspects in cases of medullary sponge kidney are defined as "bouquet of flowers", "bunch of grapes" or "brush". None of the other methods of imaging available today has the same diagnostic accuracy.

The remarkable progresses of imagistic and interventional techniques that have been implemented during the last decades facilitated the diagnostic and allowed the treatment indication changes for numerous renal disorders. The purpose of the present lecture was to outline a data review concerning a renal anomaly first described one century ago as well as to evaluate the impact of endourologic technical progresses over the therapeutic management of the respective disease. The medullary sponge kidney (MSK) or Cacchi-Ricci disorder represents a disturbance in the renal development characterized by the cystic type dilation and diffuse precalyceal ducts ectasias...
