lo Background Acute glomerulonephritis refers to a specific set of renal diseases in which an immunologic mechanism triggers inflammation and proliferation of glomerular tissue that can result in damage to the basement membrane‚ mesangium‚ or capillary endothelium. Hippocrates originally described the manifestation of back pain and hematuria‚ which lead to oliguria or anuria. With the development of the microscope‚ Langhans was later able to describe these pathophysiologic glomerular changes

Multiplication of contaminant bacteria in urine and interpretation of delayed culture. Abstract A prospective study of the bacterial populations of non-infected urine was mounted in an attempt to define the length of delay between voiding and analysis during which culture would not give false positive results due to the multiplication of contaminant bacteria present at the time of voiding. The findings suggest that culture of urine within four hours of voiding is likely to give a true indication

Renal calculi literally translates to kidney stones. These kidney stones form inside your kidneys but can affect your entire urinary tract as it travels (which includes the bladder‚ urethra‚ and ureters.)

Kidney stones are a collection of proteins and mineral salts that aggregate into a solid crystalline structure. The stones structure is made of two phases‚ crystalline

514). Through its vascular and tubular components‚ the nephron performs three basic functions in order to carry out its regulatory role in the kidney: glomerular filtration‚ tubular reabsorption‚ and tubular secretion. In the initial phase of urine creation‚ otherwise known as glomerular filtration‚ roughly 20% of plasma from the afferent arteriole flows through the glomerular capillaries and into the Bowman’s capsule. As this newly formed filtrate travels through the nephron‚ it is subject

A Summary of Alkaptonuria Alkaptonuria is an inborn error of metabolism that presents most notably with the occurrence of black urine when the urine is exposed to air. For this reason‚ it is also called the “Black Urine” disease. It is an autosomal recessive disorder and is therefore inherited genetically. Alkaptonuria is very rare‚ with a presentation of about 1:250‚000(ref1). The causality behind Alkaptonuria is a deficiency in homogentisic acid 1‚2 dioxygenase‚ an enzyme that is found in the
