To accomplish isolation and removal of a substance from a vasculature, a catheter is employed to occlude a vessel of the vasculature. The substance is thus isolated in the vasculature and can be removed. In this way, the substance is removed before entering other parts of the circulatory system. This method is applicable to removal of contrast from the coronary sinus shortly after injection of the coronary arteries with the contrast. The method substantially minimizes or avoids renal dysfunction caused by angiographic procedures in which contrast must be injected. Such angiographic procedures are often performed during intervention procedures. This method substantially prevents circulation of the contrast to the kidneys where it could otherwise cause renal dysfunction or failure. The apparatus for implementation of the method is also disclosed.

Improved devices, systems, and methods treatment of patients can be used to help mitigate injury to the kidneys by applying cyclical mechanical pressure energy at low intensities. The energy often be selectively directed from non-invasive transducers disposed outside the patients. The energy will typically comprise low frequency ultrasound energy, shock wave energy, or the like, and may induce the generation and / or release of nitric oxide, thereby enhancing perfusion and ameliorating tissue damage. Superimposed micro and macro duty cycles may help avoid thermal and other injury to tissues of the patient during treatment. Bilateral treatments are facilitated by a support structure that orients at least one transducer toward each kidney.

The present invention provides compositions and methods for the detection, treatment, and prevention of a kidney injury. The invention relates to the discovery that chitinase 3-like 1 / Brp-39 / YKL-40 serves as both a biomarker for the degree of kidney injury and a critical mediator of a reparative response in the kidney.

The p21 biomarker is utilized in the evaluation of whether a patient is suffering from kidney injury or failure, and can be used in methods of treating kidney injury or failure by determining the appropriateness of one or more of initiating renal replacement therapy, withdrawing delivery of compounds that are known to be damaging to the kidney, delaying or avoiding procedures that are known to be damaging to the kidney, and modifying diuretic administration.

The invention discloses an isolated kidney perfusion system, and relates to the technical field of kidney transplantation. According to the invention, a liquid conveying pipeline is used as a main body; a liquid inlet pipe, a liquid dripping bucket, a fluid speed regulation roller and an outflow assembly are sequentially arranged on the conveying pipeline in series; and through arrangement of theabove-mentioned structures, the isolated kidney perfusion system provided by the invention can make up the defect that a perfusion device used in the kidney transplantation process in the prior art isgenerally a self-made simple device and is inconvenient when a plurality of blood vessels are encountered or the blood vessels are thin. During kidney perfusion, a medicine can be injected through above-mentioned devices; a flow speed can be adjusted through a pulley; a pressure can be generated during liquid conversion and extrusion through a soft ball to facilitate perfusion; a proper siliconetube can be selected for perfusion according to the thickness and number of kidney arteries; thus, the isolated kidney perfusion system provided by the invention has the advantages of simple structure, widely-available materials, convenient operation, low price, practicality, sufficient perfusion, scientific and reasonable structure and safe and convenient use.

In some preferred embodiments, a system for the automatic identification of cortical and / or medulla regions of the kidneys in renal dynamic studies is provided that includes: a computer module configured to perform principal component analysis on a dynamic sequence corresponding to only one of the kidneys based on a linear combination of the first few component images with coefficients for the principal component analysis as normalization factors.

The p21 biomarker is utilized in the evaluation of whether a patient is suffering from kidney injury or failure, and can be used in methods of treating kidney injury or failure by determining the appropriateness of one or more of initiating renal replacement therapy, withdrawing delivery of compounds that are known to be damaging to the kidney, delaying or avoiding procedures that are known to be damaging to the kidney, and modifying diuretic administration.

The present invention relates to means and methods for modifying renal function in a subject, comprising selecting a patient requiring an increment in renal function; emitting a quantity of ultrasound radiation, enough to provide an increment in renal function, to at least one part of a kidney for a period of time from about 1 hours to about 30 days.

The invention discloses a method for automatically evaluating difficulty of kidney tumor enucleation based on CT (computed tomography) images, which comprises the following steps: based on artificial intelligence and image analysis technologies, segmenting an abdominal wall, a kidney and a kidney tumor at the same time by establishing a deep network model, automatically calculating an MAP score and an R.E.N.A.L score by utilizing relevance among the tumor, a renal pelvis, the kidney and the abdominal wall, and automatically evaluating the difficulty of the kidney tumor enucleation based on the CT images. Therefore, the difficulty of the kidney tumor enucleation is reasonably and effectively evaluated; the method has the advantages of time and labor saving and high evaluation accuracy and reliability.

The present invention relates to the context of renal denervation. In order to provide further improvement in relation to the outcome of renal denervation, an apparatus (10) for renal denervation preparation is provided that comprises an input unit (12), ha processing unit (14) and an output unit (16). The input unit is configured to receive first artery parameter data and second artery Ge parameter data. The first artery parameter data relates to artery stiffness of a renal artery part of a subject, and the second artery parameter In data relates to artery stiffness of a non-renal artery part of the subject. The processing unit is configured to calculate a respective vessel stiffness for the renal artery part based on the first artery parameter data, and to calculate a respective vessel stiffness for the non-renal artery part based on the second artery parameter data, and also to determine a response parameter for renal denervation based on the vessel stiffness for the renal artery part and the vessel stiffness for the non-renal artery part. The output unit is then configured to provide the response parameter.

The present teaching relates to interactive medical image processing for surgical procedure planning. In one example, a three dimensional (3D) image of a kidney is obtained. The three dimensional image is rendered on a display screen. An input is received from a user specifying a location with respect to a representation of the kidney in the rendered three dimensional image. A representation of an instrument is rendered on the display screen based on the location. The instrument is automatically aligned with an infundibulum pathway of calyx at the location with respect to the kidney. A graphical line extension is rendered on the display screen to visualize the alignment of the instrument. One or more measurements related to the kidney are determined based on the location and an anatomical structure of the kidney.

The invention belongs to the field of diagnostic pharmacology, and relates to the use of nano-gold probes in the early diagnosis of kidney damage, especially the use of nano-gold probes in the early diagnosis of kidney damage in diabetic nephropathy. The experimental results of the present invention show that the kidney damage induced under the condition of unilateral ureteral obstruction and release can be detected by the nano gold probe, but cannot be detected by traditional blood biochemical indicators and tissue section methods. Indicating the role of nano-gold probes in the early diagnosis of kidney injury. The nano-gold probe of the present invention detects kidney damage through different particle sizes, and the nano-gold probe of the present invention provides meaningful reference data and support for a new method of diagnosing kidney damage.
