AIMS: To evaluate the usefulness of the cyst-to-kidney volume ratio determined by ultrasonography (US) in unilateral multicystic dysplastic kidney (MCDK) in children. MATERIAL AND METHODS: Our study group included 21 children (average age: 431 days) with unilateral MCDK and 22 children (average age: 440 days) with unilateral grade IV hydronephrosis due to ureteropelvic junction obstruction as the control group. All the children underwent transabdominal US. In children with MCDK, we calculated cyst-to-kidney volume ratios (volume of the largest cyst/volume of the MCDK) and in the control group the volume ratios of the renal pelvis and the largest calyx (volume of the pelvis or largest calyx/volume of the ipsilateral hydronephrotic kidney)...

Cases of renal cell carcinoma (RCC) presenting as a simple cyst are extremely rare. We herein report the case of a patient with RCC diagnosed as a simple renal cyst preoperatively. A 39-year-old female patient presented with abdominal pain for 3 months. Ultrasonography and contrast-enhanced computed tomography revealed a simple cyst in the left kidney. The patient underwent laparoscopic decortication of the renal cyst. Biochemical analysis of the cystic fluid revealed unusually low levels of potassium, sodium, calcium and glucose, and the histological examination of the floor of the cyst indicated malignancy...

BACKGROUND: Previous studies have shown that a higher resistive index (RI) on renal duplex ultrasonography was related with renal progression and acute kidney injury, especially in patients with chronic kidney disease (CKD) using an angiotensin converting enzyme inhibitor (ACEI) or angiotensin receptor antagonist (ARB). We evaluated whether a RI value is a predictive factor for renal progression regardless of ACEI or ARB medication in patients with moderate renal dysfunction. METHODS: We retrospectively analyzed 119 patients with moderate renal dysfunction that had been evaluated with renal duplex ultrasonography from February 2011 to April 2015...

The number of type 2 diabetic patients is increasing world-wide and a prediction of prevalence of chronic kidney disease up to 2025 in European diabetic population is alarming. Albuminuria and estimated glomerular filtration rate are cardinal biochemical parameters in diagnostics of diabetic nephropathy. Following diagnostic methods are also used: renal ultrasonography, ophthalmoscopy and in not clarified cases renal biopsy. Long-term optimal glycemic control, efficient antihypertensive treatment by angiotensin converting enzyme inhibitor, or angiotensin receptor blocker and recommended protein intake is a cornerstone of therapy...

BACKGROUND: Kidney transplant candidates undergo rigorous testing prior to clearance for transplantation. Because kidney transplant candidates may be at increased risk for carotid artery stenosis because of arteriosclerosis and atherosclerosis secondary to hypertension, vascular calcification, and diabetes, carotid ultrasound is often performed with the intent of preventing a cerebrovascular accident in the perioperative or posttransplant period. To our knowledge, there has not been a study investigating the utility of screening carotid ultrasonography in pretransplant candidates...

BACKGROUND: Nutcracker syndrome (NCS) describes left renal vein compression between the superior mesenteric artery and the aorta. Although uncommon, it is an important diagnosis due to the important morbidity associated with it, including the risk of chronic kidney disease from long-term left renal vein (LRV) hypertension and the risk of LRV thrombosis. METHODS: This article reviews the literature on NCS, particularly with respect to the diagnostic accuracy of different imaging modalities and the success rates, complications, and long-term follow-up data associated with various surgical interventions...

BACKGROUND/AIMS: Dietary factors can modify calciuria. We aim to investigate urinary calcium excretion in healthy infants according to their protein. METHODS: Secondary data analysis from a randomized clinical trial where healthy term infants were randomized after birth to a higher (HP) or lower (LP) protein content formula that was consumed until age 1 year. A non-randomized group of breastfed (BF) infants was used for reference. Anthropometry, dietary intakes and calciuria (calcium/creatinine ratios) from spot urine samples were assessed at ages 3 and 6 months...

Sclerochoroidal calcification (SCC) is a frequent masquerader of choroidal melanoma with important systemic associations such as hyperparathyroidism and parathyroid adenoma. Herein, we describe a case of a 67-year-old male who presented with an amelanotic choroidal lesion in the right eye (OD) and a history of kidney stones. Ultrasonography showed the lesion to be flat and calcified OD. Incidentally, a subclinical calcified plaque was also found in the fellow eye. Optical coherence tomography showed an elevated suprachoroidal mass in a table mountain configuration OD and flat configuration left eye, consistent with type 4 and type 1 SCC...
