Renal ultrasound (US) is a common examination, which has been performed for decades. Using B-mode imaging, assessment of renal anatomy is easily performed, and US is often used as image guidance for renal interventions. Furthermore, novel applications in renal US have been introduced with contrast-enhanced ultrasound (CEUS), elastography and ...
The signs and symptoms of hydronephrosis depend upon whether the obstruction is acute or chronic, partial or complete, unilateral or bilateral.Hydronephrosis that occurs acutely with sudden onset (as caused by a kidney stone) can cause intense pain in the flank area (between the hips and ribs) known as a renal colic.
There are two poles in the renal corpuscle, a vascular pole and a tubular pole. [4] The vascular pole is a location of the glomerulus. At the vascular pole, the afferent arterioles and efferent arterioles enter and leave the glomerulus in the Bowman's capsule. The tubular pole is at the other end opposite to the vascular pole.
The renal corpuscle consists of the glomerulus, and the glomerular capsule or Bowman's capsule. [4]: 1027 The renal corpuscle has two poles: a vascular pole and a tubular pole. [5]: 397 The arterioles from the renal circulation enter and leave the glomerulus at the vascular pole. The glomerular filtrate leaves the Bowman's capsule at the renal ...
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
Pyonephrosis (from Greek pyon 'pus' and nephros 'kidney' [1]) is a dangerous kidney infection that is characterized by pus accumulation in the renal collecting system. [2] It is linked to renal collecting system blockage and suppurative renal parenchymal destruction, which result in complete or nearly complete kidney failure. [3]
Glomerulosclerosis is the hardening of the glomeruli in the kidney.It is a general term to describe scarring of the kidneys' tiny blood vessels, the glomeruli, the functional units in the kidney that filter urea from the blood.
Renal infarction is a medical condition caused by an abrupt disruption of the renal blood flow in either one of the segmental branches or the major ipsilateral renal artery. [3] Patients who have experienced an acute renal infarction usually report sudden onset flank pain , which is often accompanied by fever , nausea , and vomiting .
