Nephrocalcinosis in adolescent girl with medullary sponge kidney and mild hemihypertrophy: A case report.

Medicine (Baltimore) 2019 Feb;98(7):e14529

Department of Pediatric Nephrology.

Rationale: Medullary sponge kidney (MSK) is a rare congenital abnormality characterized by cystic dilatation of the medullary collecting tubules. The disorder is likely to be complicated by nephrocalcinosis, urolithiasis, tubular dysfunctions, and urinary tract infections. In addition, it may be rarely associated with extrarenal anomalies.

Heterozygous Pkhd1 mice develop cystic liver disease and proximal tubule ectasia that mimics radiographic signs of medullary sponge kidney.

Am J Physiol Renal Physiol 2019 Mar 2;316(3):F463-F472. Epub 2019 Jan 2.

Department of Medicine, The University of Alabama at Birmingham , Birmingham, Alabama.

Heterozygosity for human polycystic kidney and hepatic disease 1 ( PKHD1) mutations was recently associated with cystic liver disease and radiographic findings resembling medullary sponge kidney (MSK). However, the relevance of these associations has been tempered by a lack of cystic liver or renal disease in heterozygous mice carrying Pkhd1 gene trap or exon deletions. To determine whether heterozygosity for a smaller Pkhd1 defect can trigger cystic renal disease in mice, we generated and characterized mice with the predicted truncating Pkhd1 mutation in a region corresponding to the middle of exon 20 cluster of five truncating human mutations (between PKHD1 and PKHD1).

Urinary proteome in inherited nephrolithiasis.

Urolithiasis 2019 Feb 18;47(1):91-98. Epub 2018 Dec 18.

Chair of Nephrology, Department of Translational Medicine, University of Campania "Luigi Vanvitelli", Naples, Italy.

In the last decades, proteomics has been largely applied to the Nephrology field, with the double aim to (1) elucidate the biological processes underlying renal diseases; (2) identify disease-specific biomarkers, predictor factors of therapeutic efficacy and prognostic factors of disease progression. Kidney stone disease, and in particular, inherited nephrolithiasis (INL) are not an exception. Given the multifactorial origin of these disorders, the combination of genomics and proteomics studies may complement each other, with the final objective to give a global and comprehensive mechanistic view.

Living kidney donation from people at risk of nephrolithiasis, with a focus on the genetic forms.

Urolithiasis 2019 Feb 23;47(1):115-123. Epub 2018 Nov 23.

UOC Nefrologia, Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome, Italy.

Deciding whether to accept a donor with nephrolithiasis is a multifaceted task because of the challenge of finding enough suitable donors while at the same time ensuring the safety of both donors and recipients. Until not long ago, donors with a history of renal stones or with stones emerging during screening on imaging were not considered ideal, but recent guidelines have adopted less stringent criteria for potential donors at risk of stones. This review goes through the problems that need to be approached to arrive at a wise clinical decision, balancing the safety of donors and recipients with the need to expand the organ pool.

Association of medullary sponge kidney and hyperparathyroidism with RET G691S/S904S polymorphism: a case report.

J Med Case Rep 2018 Jul 9;12(1):197. Epub 2018 Jul 9.

Department of Endocrinology, The Third Xiangya Hospital, Central South University, Tongzipo Road, Changsha, 410007, Hunan Province, People's Republic of China.

Background: Medullary sponge kidney is a rare renal malformation, which usually manifests as nephrocalcinosis, renal tubular acidosis, and recurrent urinary tract infections. Medullary sponge kidney is often associated with renal developmental anomalies and tumors, and its exact pathogenesis is not yet clearly explained. Given the key role of the interaction of glial cell line-derived neurotrophic factor gene, GDNF, and the "rearranged during transfection" proto-oncogene, RET, in kidney and urinary tract development, variations in these genes are proposed to be candidates for medullary sponge kidney.

Smith Institute for Urology, Hofstra Northwell School of Medicine, New Hyde Park, New York, NY, USA.

Objective: To expand the diagnostic armamentarium for medullary sponge kidney (MSK), we evaluate the use of high-resolution multidetector computed tomography (MDCT) for MSK diagnosis and compare to the standard intravenous urography (IVU). Despite a significant prevalence amongst stone formers, diagnosis of this well described condition has declined. IVU, the gold standard in MSK diagnosis, has largely been replaced by CT, which has previously been shown unable to demonstrate signs of MSK. Read More

The genetic framework for development of nephrolithiasis.

Asian J Urol 2017 Jan 28;4(1):18-26. Epub 2016 Nov 28.

Smith Institute for Urology, Hofstra Northwell School of Medicine, Lake Success, NY, USA.

Over 1%-15% of the population worldwide is affected by nephrolithiasis, which remains the most common and costly disease that urologists manage today. Identification of at-risk individuals remains a theoretical and technological challenge. The search for monogenic causes of stone disease has been largely unfruitful and a technological challenge; however, several candidate genes have been implicated in the development of nephrolithiasis.

New non-renal congenital disorders associated with medullary sponge kidney (MSK) support the pathogenic role of GDNF and point to the diagnosis of MSK in recurrent stone formers.

Urolithiasis 2017 Aug 29;45(4):359-362. Epub 2016 Aug 29.

Division of Nephrology, Department of Medical Sciences, Catholic University of the Sacred Heart, Rome, Italy.

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.

Urology Department, São José do Rio Preto School of Medicine, Avenida Brigadeiro Faria Lima 5416, São José do Rio Preto, SP 15090-000, Brazil.

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. Read More

Purpose: We assessed whether a combination of the fibrin tissue adhesive Tisseel® (human fibrinogen and thrombin) plus the hemostatic matrix FloSeal® (bovine derived gelatin matrix/human thrombin) could safely replace the conventional deep medullary suture without compromising outcomes.

Materials And Methods: Laparoscopic mid pole and one-third partial nephrectomy was performed on the right kidney of 12 female pigs. The only difference between the 2 groups of 6 pigs each was the use of a fibrin tissue adhesive plus hemostatic matrix combination in group 2 instead of the deep medullary running suture in control group 1.

The impact of modern endourological techniques in the treatment of a century old disease--medullary sponge kidney with associated nephrolithiasis.

J Med Life 2013 25;6(4):482-5. Epub 2013 Dec 25.

"Sf. Ioan" Clinical Emergency Hospital, Bucharest, Romania.

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.

Medullary sponge kidney on retrograde pyelography.

Chonnam Med J 2014 Apr 22;50(1):21-2. Epub 2014 Apr 22.

Department of Urology, Kaohsiung Medical University Hospital, Kaohsiung Medical University, Kaohsiung, Taiwan. ; Department of Urology, Faculty of Medicine, College of Medicine, Kaohsiung Medical University, Kaohsiung, Taiwan.

A woman aged 31 had recurrent urinary tract infection with bloody urine. A series image of medullary sponge kidney presented by intravenous urography (IVU) was detected dynamically by retrograde pyelography (RP). Other than ultrasonography and IVU, RP is also a reliable method to detect medullary sponge kidney. Read More

Medullary sponge kidney and testicular dysgenesis syndrome: a rare association.

Case Rep Urol 2014 18;2014:841781. Epub 2014 Feb 18.

Department of Life, Health & Environmental Sciences, University of L'Aquila, "Giuseppe Mazzini" General Hospital, Teramo, Italy.

The medullary sponge kidney is also known as Lenarduzzi's kidney or Cacchi and Ricci's disease from the first Italian authors who described its main features. A review of the scientific literature underlines particular rarity of the association of MSK with developmental abnormalities of the lower urinary tract and genital tract such as hypospadias and bilateral cryptorchidism. The work presented is the only one in the scientific literature that shows the association between the medullary sponge kidney and the testicular dysgenesis syndrome. Read More

CT urography for the diagnosis of medullary sponge kidney.

Am J Nephrol 2014 11;39(2):165-70. Epub 2014 Feb 11.

Section of Nephrology, Yale University School of Medicine, New Haven, Conn., USA.

Background: Medullary sponge kidney (MSK) is characterized by malformation of the terminal collecting ducts and is associated with an increased risk of nephrolithiasis, nephrocalcinosis, urinary tract infections, renal acidification defects, and reduced bone density. It has been historically diagnosed with intravenous pyelography (IVP), which is falling out of favor as an imaging modality. CT urography (CTU) performed with multidetector CT (MDCT) has been shown to create images of the renal collecting system with similar detail as IVP; however, its utility in diagnosing MSK has not been defined.

A rare case of congenital distal renal tubular acidosis combined with medullary sponge kidney.

Urol Int 2014 10;92(2):246-9. Epub 2013 Jul 10.

Department of Pediatrics, Hangzhou First People's Hospital, Hangzhou, PR China.

Distal renal tubular acidosis combined with medullary sponge kidney (MSK) is not uncommon in adults, but is rare in infants. We report a 13-month-old boy with MSK who had features of distal renal tubular acidosis (nephrocalcinosis, hypercalciuria, hypocitraturia) and failed to thrive. Renal ultrasound revealed bilateral increased medullary echogenicity and nephrocalcinosis. Read More

Medullary sponge kidney.

Curr Opin Nephrol Hypertens 2013 Jul;22(4):421-6

Nephrology Division, Department of Internal Medicine and Medical Specialties, Columbus-Gemelli University Hospital, Rome, Italy.

Purpose Of Review: After it was first described in 1939, medullary sponge kidney (MSK) received relatively little attention. This was because it was believed to have a low prevalence and because it was considered a benign condition. Studies in recent years have been changing these convictions however, hence the present review. Read More
