Hyperoxaluria associated with renal deposition of calcium oxalate (CaOx) crystals causes renal injury and inflammation leading to number of diseases including chronic kidney disease (CKD). It is however, not been possible to separate the renal consequences of hyperoxaluria from that of CaOx crystal deposition. We decided to utilize ethylene glycol (EG) model where hyperoxaluria and CaOx crystal deposition can be separated in time. To test our hypothesis, male rats were made hyperoxaluric by administering EG, rats were euthanized and kidneys were extracted on day 14, when occasional crystal is seen in the kidneys and day 28, when all animals have developed renal CaOx crystal deposits...

The objective of this study is to evaluate the average radiation exposure in children with renal stones before SWL treatment. Mean radiation exposure values were evaluated in 110 children before SWL treatment. While some children referred to the emergency department (ED) with colic pain, remaining cases referred to outpatient department (OD). Although low-dose NCCT was performed in ED; KUB and abdominal sonography were first performed in other cases referring to OD where CT has been applied if needed. The type of imaging modality used and the mean radiation exposure were evaluated and comparatively evaluated with respect to the department referred, patient as well as stone related parameters...

PURPOSE: The treatment of a first-time renal stone episode consists of acute management followed by medical efforts to prevent stone recurrence. Though nephrolithiasis is roughly 50% heritable, the presence of a family history usually does not affect treatment, as most stone disease is regarded as polygenic, i.e. not attributable to a single gene. Recently, new evidence has suggested that single mutations could be responsible for a larger proportion of renal stones than expected. This intriguing possibility holds the potential to change the management paradigm in stone prevention from metabolically-directed therapy to more specific approaches informed by genetic screening and testing...

Preoperative nomograms offer systematic and quantitative methods to assess patient- and stone-related characteristics and their impact on successful treatment and potential risk of complication. Discrepancies in the correlation of perioperative variables to patient outcomes have led to the individual development, validation, and application of four independent scoring systems for the percutaneous nephrolithotomy: Guy's stone score, S.T.O.N.E. nephrolithometry, Clinical Research Office of the Endourology Society nomogram, and Seoul National University Renal Stone Complexity...

OBJECTIVES: Extracorporeal shock wave lithotripsy (ESWL) is a method used frequently for the treatment of renal stone disease. Although its safety is proven, there are still concerns about its unwanted effects on kidneys. In this prospective study, we aimed to evaluate renal tissue alterations with shear wave elastography (SWE) after ESWL. We also studied the correlation between SWE and resistive index (RI) changes. METHODS: The study included 59 patients who underwent ESWL treatment for renal stone disease...

With the recent introduction of more potent modern immunosuppressive regimens in solid-organ transplant, new types of viral infections such as adenovirus are emerging as a potential cause for graft dysfunction and loss. We report a case of 41-year-old male patient with end-stage renal disease from recurrent kidney stones who underwent kidney transplant from a deceased 12-year-old female donor. He developed adenoviral infection with acute cystitis, microscopic hematuria, and necrotizing interstitial nephritis associated with graft dysfunction within the first month of the postoperative period...

In solid organ transplant recipients, Epstein-Barr virus (EBV) can cause active central nervous system (CNS) infection or malignant transformation of latently infected cells in the CNS, known as post-transplant lymphoproliferative disease (PTLD). Reduction of T-cell immunosuppression is the cornerstone of management. The role of antivirals with in-vitro activity against herpesviruses in EBV-related CNS syndromes is controversial, as they have no effect on latent virus. We report an unusual case of relapsing EBV encephalitis in a donor-positive, EBV-negative renal transplant recipient, with response to valganciclovir...

This article discusses points to consider when undertaking a clinical trial to test therapy for renal involvement in SSc, not including scleroderma renal crisis. Double-blind, randomized controlled trials vs placebo or standard background therapy should be strongly considered. Inclusion criteria should consider a pre-specified range of renal functions or stratification of renal function. Gender and age limitations are probably not necessary. Concomitant medications including vasodilators, immunosuppressants and endothelin receptor antagonists and confounding illnesses such as diabetes, kidney stones, hypertension and heart failure need to be considered...

INTRODUCTION: The most common cause of chronic hypercalcemia is primary hyperparathyroidism (PHPT). However, owing to the diverse presentation of hypercalcemia, the diagnosis often goes unnoticed culminating as a continuum of recurrence of symptoms. Nephrolithiasis, decreased bone mineral density and peptic ulcer disease are the main clinical sequelae. Among the causes of PHPT 80% are caused by parathyroid adenomas (PA). However, only rarely, these adenomas are found ectopically. PRESENTATION OF CASE: We present the case of a 66-year-old female with a history of recurrent renal stones and peptic ulcer disease...
