MS Renal Disorders W9

Midterm

Nephron

Functional unit and responsible for formation of filtrate

formation of filtrate

this will become the urine

Renal Artery

arises from abdominal aorta which is further divided into Afferent and Efferent Arterioles

Afferent Arterioles

branch to form glomerulus and once blood leaves glomerulus, it will travel to the efferent arterioles

Glomerulus

area of filtration

Efferent Arterioles

when blood leaves the glomerulus, these are the blood bessels that will bring the blood gloing back to the IVC, to the heart through a network of capillaries (Pertibular Capilaries)

Pertibular Capilaries

have a role in reabsorption & secretion of substances

Bowmans Capsule

Enclosure of the glomerulus, the tubular component of nephron begins in here.

Proximal convulated tubules

the filtrate that is created in the bowman capsule will travel first here and the other tubular components

Thin discending limb (of the loop of henle), thick ascending limb (of the loop of henle), distal convulated tubule, collecting duct

what are the other tubular components after proximal convulated tubule?

H2O and small molecules

the filltrate normally ocnisist of

Larger molecules and cells

what are not filtered and they stay in the blood stream circulation

H2O, small molecules, (na, K, Cl, Ca, HCO3, glucose)

substances that passes the filtration

urea, creatinine, uric acid

metabolic waste that passes the filtration

Larger molecules and cells (RBC, the rest of the blood components)

substances that are not allowed to pass the filtration

Hydrostatic pressure

what is the pressure on glomerulus

glomerular filtration and rubular absorption and secretion

urine is formed in the nephrons through 3 complex steps process which are the

Intravenous Pyelogram

a special x-ray imaging of the kidneys, uterus and bladder where in it will show the size, shape and position of the urinary tract as well as the collecting system of the kidneys

IV urogram

Intravenous Pyelogram is also called as

renal colic pain, Presence of hematuria, suspection of Kidney stones

Intravenous Pyelogram may be done as an emergency procedure w/c requires no preparation, this indications of emergency IVP are:

IVP

x-ray with contrast medium, consent of the pt and pt allergie

KUB

X-ray only and full bladder

Cytoscopy

Examination of bladder mucosa for inflammation, calculi or tumors by means of a _; sample biopsy can be obtained

Lithotomy

pt positon on Cytoscopy
