INTRODUCTION Medullary sponge kidney is a congenital anomaly characterized by diffuse ectasy of the collecting tubules of one or both kidneys. It is usually diagnosed in the second or third decade of life. CASE PRESENTATION Distal renal tubular acidosis is commonly observed in patients with medullary sponge kidney. We describe here a 50-day-old Egyptian Caucasian girl with medullary sponge ki...

INTRODUCTION The most common hereditary kidney condition is autosomal dominant polycystic kidney disease. It is the cause of 5-10% of end-stage renal disease. Its symptoms are generally late-onset, typically leading to development of hypertension and chronic kidney disease. Ultrasonography is the imaging modality of choice in its diagnosis and management. The aim of this study is to determine t...

Non-calcified echogenic renal cortical nodules are commonly detected with abdominal ultrasound (US). The majority of these nodules represent benign angiomyolipomas (AMLs), which are present in 0.3–2.1 % of the population at autopsy [1]. The increased echogenicity (in the absence of calcification) of renal AML is due to the presence of gross or mature fat within the nodule [2]. Although renal AM...

Renal biopsies were carried out on 229 dogs using an echo-assisted, semi-automatic method. Complications arising after the biopsy were also evaluated. The biopsies were examined for the accuracy of diagnosis and the presence of histologically demonstrable primary renal pathologies. A retrospective study of the observed lesions and parenchymal echogenicity showed a correlation between these fact...

case presentation a preterm neonate with suspicious rt renal mass and oligohydramnios at prenatal ultrasound was hospitalized due to respiratory distress and hypertension. although postnatal ultrasound showed enlarged echogenic rt kidney and normal sized echogenic lt kidney, regarding to linear array transducer findings, arpkd was considered rather than renal mass. the diagnosis was confirmed a...

Chronically increased echogenicity on renal ultrasound is a sensitive early finding of chronic kidney disease that can be detected before manifestation of other symptoms. Increased echogenicity, however, is not specific for a certain etiology of chronic kidney disease. Here, we performed whole exome sequencing in 79 consanguineous or familial cases of suspected nephronophthisis in order to dete...

-We have demonstrated a significant, directionally dependent, anisotropic, echogenicity from the cortices of two sheep kidneys and a normal human cadaver kidney. The anisotropy corresponds to the relationship of the sound field to the medullary rays and interiohalar arteries. At 7.5 MHz, the hackscatter from specimens of cortex of a sheep kidney was 4.7 _+ .7 dB (mean + SEM) greater in parts of...

Total 450 Type2 Diabetic pts aged 35 yrs to >70 yrs attending the OPD at MLB Medical College were studied. Out of 450 pts 89 had abnormal USG. Out of 89 pts, 36 had kidney abnormalities, 32 had liver and 21 had both liver and kidney abnormalities. Most cases showed normal renal size and echogenicity (89%). Grade 1 nephropathy was more common than grade 2 or 3 nephropathy. The most common renal...

BACKGROUND Renal impairment is a common complication of multiple myeloma occurring in up to 50 % of patients at some stage in their disease. Due to occurrence of cast nephropathies we hypothesized circulatory dysregulation (vasoconstriction) in the kidneys with measurable elevation of the resistance index among these patients which would have a diagnostic impact. SUBJECTS AND METHODS 36 patie...
