The Effect of Pre-treatment Biopsy for Non-neoplastic Renal Disease vs no Biopsy on Estimated Glomerular Filtration Rate in Patients With Small Renal Mass: a Single-center, Single-blinded, Randomized, Parallel Group Clinical Trial
The purpose of this study is to determine if biopsy for non-neoplastic renal disease for patients with a small renal mass results in greater postoperative renal function than the current s...
The purpose of this study is to evaluate the blood flow in kidney masses by using ultrasound microbubble contrast material, and to see if results from ultrasound contrast studies can predi...
This clinical trial studies a type of ultrasound called robot-assisted laparoscopic high-intensity focused ultrasound for performing thermal ablative therapy, or sound wave therapy, in tre...
The incidence of the diagnosis of renal cell carcinoma has increased during the past two decades because of the detection of small renal tumours that occur incidentally because of increase...
A prospective, randomized, controlled trial including patients who are diagnosed with a small renal mass (
Opponents of premanagement biopsy of small renal masses are not difficult to find. Many urologists contend that the benefits of biopsy do not outweigh the risks, arguing that the results do not influe...
Kidney cancer accounts for approximately 2-3 % of all types of cancers. Renal tumors prevalence and especially the prevalence of small renal tumors, is on the rise. About half of the tumors currently ...
Kidney cancer represents about 5% of all new cancer diagnoses. The most common form of kidney cancer arises from renal epithelium, named renal cell carcinoma (RCC). This entity comprises different his...
This paper studies the feasibility of developinga fast and accurate automatic kidney component segmentation method. The proposed method segments the kidney into four components: renal cortex, renal co...
Malignancy following renal transplantation remains inconsistent with the reported safety of kidney donation during the long-term follow-up.
Conditions in which the KIDNEYS perform below the normal level in the ability to remove wastes, concentrate URINE, and maintain ELECTROLYTE BALANCE; BLOOD PRESSURE; and CALCIUM metabolism. Renal insufficiency can be classified by the degree of kidney damage (as measured by the level of PROTEINURIA) and reduction in GLOMERULAR FILTRATION RATE. The most severe form is KIDNEY FAILURE. Renal function may deteriorate slowly (RENAL INSUFFICIENCY, CHRONIC) or precipitously (RENAL INSUFFICIENCY, ACUTE).
Conditions in which the KIDNEYS perform below the normal level for more than three months. Chronic kidney insufficiency is classified by five stages according to the decline in GLOMERULAR FILTRATION RATE and the degree of kidney damage (as measured by the level of PROTEINURIA). The most severe form is the end-stage renal disease (CHRONIC KIDNEY FAILURE). (Kidney Foundation: Kidney Disease Outcome Quality Initiative, 2002)
A complication of kidney diseases characterized by cell death involving KIDNEY PAPILLA in the KIDNEY MEDULLA. Damages to this area may hinder the kidney to concentrate urine resulting in POLYURIA. Sloughed off necrotic tissue may block KIDNEY PELVIS or URETER. Necrosis of multiple renal papillae can lead to KIDNEY FAILURE.
A solid, unencapsulated tumor of the KIDNEY composed of spindle mesenchymal cells that resemble FIBROBLASTS or muscle cells. The homogeneous mass typically extends into the renal parenchyma and replaces most of the kidney. In most cases, mesoblastic nephroma is benign and occurs in the fetus or newborn, and rarely in the older child or the adult.
A mass spectrometry technique using two (MS/MS) or more mass analyzers. With two in tandem, the precursor ions are mass-selected by a first mass analyzer, and focused into a collision region where they are then fragmented into product ions which are then characterized by a second mass analyzer. A variety of techniques are used to separate the compounds, ionize them, and introduce them to the first mass analyzer. For example, for in GC-MS/MS, GAS CHROMATOGRAPHY-MASS SPECTROMETRY is involved in separating relatively small compounds by GAS CHROMATOGRAPHY prior to injecting them into an ionization chamber for the mass selection.
