Mesenchymal stromal cells (MSC) are potential renal therapeutics. Clinically, results are mixed partly because MSC tropism to kidneys is minimal following infusion. Ultrasound augmentation of the renal microenvironment is becoming increasingly-important in renal MSC therapies. We demonstrated pulsed-focused-ultrasound (pFUS) increases enhanced homing permeability and retention of MSC in mouse kidneys. Here, we characterized the temporal proteomic response to pFUS in mouse kidneys and its association with MSC tropism...

: European Society of Hypertension/European Society of Cardiology guidelines recommend calculation of estimated glomerular filtration rate and evaluation of urinary albumin excretion rate as routine tests in the initial evaluation and during the follow-up of all hypertensive patients. However, from a clinical point of view, renal ultrasound - a noninvasive, readily available and cheap imaging modality - could contribute to the better evaluation of a hypertensive patient by identifying common causes of secondary hypertension (HTN) originating from the kidney and more recently by detecting renal injury in severe or long-standing essential HTN by measuring renal resistive indexes...

BACKGROUND: Overweight has been related to renal arteriolosclerosis and is able to modify intrarenal hemodynamics. Increasing evidences suggest an association between weight excess and primary glomerulonephritis (GN). The aim of this study was to evaluate the relationship between nutritional status and intrarenal arterial stiffness in primary GN associated to arteriolosclerosis. We have considered the glomerular diameter (GD) as morphological parameter in overweight and obese patients...

Lymphangioma is a rare, benign mesenchymal neoplasm, which is characterized by numerous intercommunicating cystic spaces containing lymphatic fluid. It is considered a congenital disease resulting from the obstruction of regional lymph drainage during the developmental period. Lymphangioma frequently occurs in the cervical neck and axilla, also in the retroperitoneum, mediastinum, mesentery, omentum, colon, and pelvis, rarely in the perirenal space. These tumors usually present in childhood, but infrequently, these also present in adults...

Deep endometriosis is usually defined as endometriosis infiltrating the peritoneum by >5 mm. It sometimes involves the ureter causing hydronephrosis in 5% of cases. The latter is associated with 18% ureteral lesions. Ureteral endometriosis is one of the rare causes of silent Kidney failure. The ureter obstruction can lead to urinary tract obstruction, hydronephrosis and hydroureters. The ureters are usually compressed externally by the endometriotic lesions surrounding it causing extrinsic ureteral endometriosis, and sometimes by pressure from the bulky adenomyotic uterus with paraureteral fibrosis...

INTRODUCTION: Dimercaptosuccinic acid (DMSA) scintigraphy is the gold standard in the evaluation of renal parenchymal defects and is widely used in the pediatric population. As more recent ultrasound equipment was purchased at our tertiary pediatric centre, our objective was to evaluate if renal ultrasound (US) results are equivalent or sufficient when compared to DMSA scintigraphy in the assessment of renal anomalies. METHODS: The charts of all 463 patients who underwent DMSA scintigraphy between January 2009 and May 2014 at our pediatric tertiary centre were reviewed...

A 54-year-old African-American man presented with 2 years of progressively worsening dyspnea and anasarca. Over the past 6 months he gained 30 lbs with worsening lower extremity, abdominal wall, and scrotal edema. A recent workup for cardiac, renal, and liver disease, including two-dimensional echocardiogram, liver and renal function tests, and abdominal ultrasound, was unremarkable. He reported a 15-pack year history of smoking and quit 3 years ago. Chest radiograph at that time revealed bilateral pleural effusions that were both reportedly milky in appearance when drained by thoracenteses...

INTRODUCTION: Renal biopsy is the diagnostic modality of choice for the diagnosis of renal parenchymal diseases. The advent of improved imaging techniques and biopsy needles over the years has increased the safety of the procedure and the ability to obtain adequate renal tissue for diagnosis. However, there is paucity of data in this regard from Pakistan. This study shall help in establishing the local perspective of the frequency of bleeding complications in percutaneous ultrasound guided renal biopsy...

Congenital adrenal hyperplasia refers to the non-malignant enlargement of adrenal gland tissue as a result of deficiency of one of several enzymes involved in adrenal hormone synthesis, secondary to a genetic mutation. 11 - Beta hydroxylase is one such enzyme, and its deficiency is a rare cause of Congenital Adrenal Hyperplasia. We describe the case of an 18-year old man who presented to us with an acute right ganglio-capsular bleed, hypertension and bilateral scrotal swelling. Investigations revealed hypokalemia, and normal renal and cardiac functions...

Renal angiomyolipoma (AML), also referred to as renal hamartoma, is a rare solid tumor without malignant characteristics. The inheritance pattern of renal AML is autosomal dominant. If the lesion grows to a large size, a series of clinical manifestations and serious complications may occur. We herein present a case of giant renal AML in a 34-year-old female patient, who presented with left-sided abdominal bloating for ~6 months. Following abdominal ultrasound and computed tomography examination, the patient underwent total left nephrectomy...

Sonja Brennan, Yogavijayan Kandasamy
Evidence is increasingly showing that prematurity results in chronic kidney disease. We hypothesized that we could use ultrasound imaging to measure and monitor the growth of the renal parenchyma in premature neonates. We conducted a prospective, case-control study to compare renal parenchymal growth between neonates born prematurely and term neonates. The study patients underwent ultrasound assessment at 32 wk postmenstrual age (PMA) and 37 wk PMA. Term neonates (gestation >37 completed wk) admitted to the neonatal unit with minor neonatal conditions were recruited into the control group...
