Q
Urinary system
A
Consists of paired, kidneys, one on each side of the spinal column, a ureter for each kidney, a bladder, and a urethra
most of the work of the urinary system takes place in the kidneys
7
Q
Kidneys
A
Filtering occurs
Are located in the dorsal (backside ) part of the abdomen.
Urine is formed in the kidneys
When blood is filtered by the kidneys, wastes are removed, but much of the water, and other substances are reabsorbed. They enter the renal vein and are returned to the bloodstream via the inferior vena cava.
average adult kidney is about 11 cm long by 6 cm wide (4 1/2 x 2 1/3“) and weighs about 145 g about 8 oz (less than half a pound). Playing a major role in hemostasis of the body, the kidneys are the major regulators of the water and pH of the blood and indirectly, all body fluids.

35
glomerulus
tubules
nephron’s components
36
Nephons have three important functions
glomerular filtration
tubular reabsorption
tubular secretion
these functions depend on a healthy blood pressure, and the ultimate goal is to filter the blood and excrete water and waste into the urine.
37
1) glomerular filtration
2) Bowman capsule
1) The glomerulus allows water, salts, wastes, and practically everything except blood cells and proteins to pass through the filter.
2) Collects the filtrate and passes it to the tubules Collects the filtrate and passes it to the two bowls.
38
tubular reabsorption
Is fluid passes through the tubules, substances that the body conserves, such as sugar, and much of the water, are reabsorbed into blood vessels surrounding the tubules.
39
tubular secretion
third process in urine formation
as fluid passes through the renal tubule, some substances from the bloodstream (waste products of metabolism in certain drugs, such as penicillin) are secreted into the tubule to be expelled into urine.
Is the secretion of some substances from the bloodstream into the renal tubule (waste products of metabolism that become toxic if they are not excreted and certain drugs, such as penicillin)
40
Tubule
Each tubule consists of a proximal tubule, a loop of Henle, and a distal tubal.
reabsorption occurs in these structures

193
urinary tract infection (UTI)
An infection of one or more structures in the urinary system is one of the more common disorders of the urinary tract. A UTI may be asymptomatic, but is usually characterized by urinary frequency and possibly discomfort during urination. Other signs and symptoms, particularly in severe infections, include backache, fever, and blood and/pus in the urine.

UTIs can include
Cystitis, urethra -itis, pyelonephritis. Most urinary infections are caused by bacteria (especially Escherichia coli), but certain fungi, (Canada) can also cause infection

Most of the time, UTIs are caused by ascending infection.
The anus serves as a reservoir for bacteria, and organisms spread directly from the anal area (occasionally the vagina) to the urethral meatus, where they multiply and can ascend throughout the urethra to the bladder and eventually the kidney in some cases. Infection is more likely in females than males, because of the short distance separating the anus and the urethra, as well as shorter urethra. Both catheterization and sexual intercourse promote the ascent of bacteria. Urinary tract infections are also more common in persons with structural abnormalities or lowered immunity and are a major type of hospital-acquired infections.

it is important that the patient have a high fluid intake after a stone is removed to prevent the formation of another stone.
271
percutaneous nephro/stomy
Nephrostomy
percutaneous kidney/incision
is a surgical procedure in which the skin of the flank (Side) is punctured so that the catheter can be inserted into the renal pelvis. Literal translation of nephrostomy is formation of a new opening into the kidney.
percutaneous tells us that the skin is punctured to gain access to the renal pelvis.
this procedure allows for drainage, drug installation, and selected surgical procedures, including dilation of a stenosed ureter or removal of calculi.

small pieces of tissue from a nearby structure are removed through the wall of the urethra
285
Transurethral resection of the prostate (TURP)
surgery is performed on the prostate gland by means of an instrument, passed through the wall of the urethra, and is sometimes done to alleviate the problems of benign prosthetic hyperplasia
an abdominal incision is not involved, because the surgeon approaches the prostate through the urethra. Small pieces of the prostate are removed with a special instrument called a resectoscope
In some cases,TURP is replaced by an less invasive laser TURP
286
