Obesity is a well-known risk factor for the development and progression of chronic kidney disease. Recently, para-perirenal ultrasonographic fat thickness (PUFT) has shown to correlate with both total and visceral fat better than body mass index (BMI), waist circumference (WC), and other indices of obesity. Moreover, a local paracrine and mechanical action of the PUFT on kidney has been described in recent studies. Aim of our study was to assess the relationship between glomerular filtration rate (GFR) and PUFT in comparison with other anthropometric and ultrasonographic indices of adiposity...

BACKGROUND Adrenocortical oncocytic neoplasms (AONs) are extremely rare tumors. AONs are classified as: oncocytoma (AO), oncocytic neoplasm of uncertain malignant potential (AONUMP), and oncocytic carcinoma (AOC). Among the 162 reported cases of AONs in the literature, 30 cases were classified as malignant. Adrenalectomy is the treatment of choice for AON. CASE REPORT We report the case of a 48-year-old man with a primitive 12-cm mass affecting the right adrenal gland, detected by ultrasonography during follow-up for alcoholic liver cirrhosis...

Carin E Reust, Amy Williams
Recurrent abdominal pain (RAP) in children is defined as at least three episodes of pain that occur over at least three months and affect the child's ability to perform normal activities. RAP is most often considered functional (nonorganic) abdominal pain, but an organic cause is found in 5% to 10% of cases. Further workup is warranted in children who have RAP and fever, vomiting, blood in the stool, more than three alarm symptoms, or a history of urinary tract infections. Physical examination findings that should prompt further workup include weight loss or failure to grow; jaundice; costovertebral tenderness or back pain with lower extremity neurologic symptoms; liver, spleen, or kidney enlargement; an abdominal mass; or localized tenderness on abdominal examination...

METHODS: A total of 20 heparinized pig kidneys were investigated at 10 intrapelvic hydrostatic pressure steps (0-90 mmHg). SWE (ARFI; Virtual TouchTM IQ, Siemens) measurements were taken at three different measuring regions and in two measuring sequences using a linear ultrasonography probe (9L4, Siemens). Median values of 10 shear-wave speed (SWS) measurements were calculated for each pressure step. Logarithmic transformed median SWS values were analyzed in a linear mixed model. RESULTS: SWS increased significantly with increasing intrapelvic pressure...

Von Meyenburg complexes (VMCs) are a rare type of ductal plate malformation. We herein report two Chinese families with VMCs, and the suspicious gene mutation of this disease. Proband A was a 62-year-old woman with abnormal echographic presentation of the liver. She received magnetic resonance imaging (MRI) examination and liver biopsy, and the results showed she had VMCs. Histologically proved hepatocellular carcinoma was found 1 year after the diagnosis of VMCs. Proband B was a 57-year-old woman with intrahepatic diffuse lesions displayed by abdominal ultrasonography...

A 21-year-old woman was referred to our hospital because of proteinuria and hematuria. She had occasional flank pain. A renal biopsy was performed and revealed a thin basement membrane. Therefore, she was diagnosed with thin basement membrane disease. However, the frequency of her flank pain increased. Since her left kidney was slightly larger than the right, nutcracker syndrome (NCS) was suspected. Renal vein ultrasonography and venography were performed, and NCS was confirmed. Her hematuria was multifactorial, and NCS can go unnoticed if there is a comorbidity that also causes hematuria...

There is growing evidence that nonalcoholic fatty liver disease (NAFLD) is associated with a higher risk of urolithiasis, but it has not yet been determined that this association is reproducible and consistent across different studies. We performed a systematic review and meta-analysis of these studies to examine the association between NAFLD and the risk of urolithiasis.We searched PubMed, EMBASE, and Google scholar using terms "fatty liver" (OR "non-alcoholic fatty liver disease" OR "non-alcoholic steatohepatitis" OR "NAFLD" OR "NASH") AND "urolithiasis" (OR "nephrolithiasis" OR "kidney stone" OR "urinary calculi" OR "renal colic" OR "urologic disease")...

Recent years have brought shear wave elastography to the attention of nephrologists as a non-invasive method for detecting kidney fibrosis and, therefore, as a potential tool for reducing the need for kidney biopsy. Few studies are performed on native kidney. We aimed to compare cortical stiffness, assessed by measuring Young's modulus (YM, kPa) with SuperSonic Imaging technology, in patients with various degrees of chronic kidney disease (CKD) compared with healthy individuals. Cortical stiffness was measured by two operators, in different sessions, in 32 patients with CKD stages 3-5 and 20 healthy individuals...

We report a rare case of two young male siblings with sickle cell anemia who presented with bilateral lower limb deformities, failure to thrive, polyuria, and polydipsia. On investigations, they were found to have normal anion gap metabolic acidosis, hypokalemia, and nephrocalcinosis were seen on ultrasonography of the kidneys. These reports were suggestive of distal renal tubular acidosis (dRTA). They were started on oral alkali replacement and potassium therapy with which clinical improvement was seen. Conventionally, renal tubular dysfunction is thought to occur infrequently in patients with sickle cell anemia...

Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare form of vasculitis associated with asthma and eosinophilia. Endothelial dysfunction has been well documented in other types of vasculitis but not in EGPA. Thirty patients (10 men and 20 women) diagnosed with EGPA and remaining in a remission, and 58 controls (24 men and 34 women) matched for age, sex, and body mass index, were enrolled in the study. We assessed each participants for typical risk factors of cardiovascular diseases and measured serum levels of vascular cell adhesion molecule-1 (VCAM-1), interleukin 6 (IL-6), and thrombomodulin...

Introduction: Imaging is a vital cog in the wheel of diagnosis and management of patients suspected with renal and ureteric calculi, and it is imperative to choose the appropriate investigation that is accurate as well as safe for the patient. At present, computed tomography (CT) is the gold standard for a patient suspected to have stone disease. However, CT scan is associated with the hazards of radiation and high cost. Ultrasonography (US) is cheap and also devoid of any radiation hazard to the patient...

BACKGROUND: Renal transplantation can significantly improve the quality of life of patients with end stage renal disease (ESRD) who would otherwise require dialysis. Renal transplant (RT) recipients have higher risks of cardiovascular disease compared with general population. The carotid intima-media thickness (CIMT) and pulse wave velocity (PWV) have been used as the important predicting factor of vascular arteriosclerosis. Therefore, this study was to investigate the improvement of carotid intima-media thickness and pulse wave velocity in renal transplant recipients...
