Homeostasis
is the process through which the body maintains a constant internal environment.
The Urinary system performs many functions that are important in maintaining homeostasis
84
Functions of homeostasis:
-Maintaining the proper balance of water, salts, and acids in the body by filtering the blood as it flows through the kidneys
-Constantly filtering the blood to remove urea, creatinine, uric acid, and other waste materials from the bloodstream.
-Converting these waste products and excess fluids into urine in the kidneys are excreting them from the body via the urinary bladder
85
urea
is the major waste product of protein metabolism
86
creatinine
is a waste product of muscle metabolism
87
urinary tract (system) consists of:
two kidneys, two ureters, one bladder and one urethra. The adrenal glands, which are part of the endocrine system, are located on the top of the kidneys
88
genitourinary tract
located in close proximity to the reproductive organs, so these two body systems are sometime referred together as this
89
kidney
constantly filter the blood to remove waste products and excess water. These are excreted as urine, which is 95% water and 5% urea and other body wastes
90
how many quarts are processed every day for the average person and how much urine does it produce
200 quarts of blood and an average of 2 quarts of urine. The kidneys also help the body maintain the proper level of fluid, hormones that control blood pressure and make red blood cells, and activate vitamin D to maintain healthy bones
91
renal
means pertaining to the kidneys
92
ren
means kidneys
93
retroperitoneal
means behind the peritoneum, which is the membrane that lines the abdominal cavity the kidneys are located here - one on each side of the vertebral column below the diaphragm and the lower edge of the rib cage
94
renal cortex
is the outer edge of the kidney. This layer of tissue contains more than one million microscopic units called nephrons.
95
cortex
means the outer portion of an organ
96
nephrons
are the microscopic functional units of each kidney. It is here that the urine is produced through the process of filtration, reabsorption, and secretion
97
reabsorption
is the return to the blood of some of the substances that were removed during filtration
98
glomerulus
which is a cluster of capillaries, surrounded by a cup-shaped membrane called the Bowman's capsule, and a renal tubule
99
renal artery
blood enters the kidney through the renal artery and flows into the nephrons
100
renal vein
after passing through the filtration system of the glomerulus, the filtered blood containing protein and blood cells leaves the kidney and returns to the bloodstream through the renal vein
-the remaining filtrate flows into the renal tubules, where elements, including some water, sugar and salts, are returned to the bloodstream via a nearby capillary
-remaining waste products are continuously converted into urine, which is transported to the renal pelvis and collected in preparation for entry into the ureters. If waste products are not efficiently removed from the bloodstream, the body cannot maintain homeostasis, with a stable balance of salts and other substances
101
renal pelvis
is the funnel-shaped area inside each kidney that is surrounded by the renal cortex and medulla. This is where the newly formed urine from the nephrons collects before it flows into the ureters
102
ureters
are two narrow tubes, each about 10 to 12 inches long, which transport urine from the kidney to the bladder.
103
Peristalsis
which is a series of wave-like contractions, move urine down each ureter to the bladder. Peristalsis is also part of the digestive process
104
uretral orifices
urine drains from the ureters into the bladder through the ureteral orifices in the wall of the urinary bladder
105
orifice
means opening
106
urinary bladder
is an oval hollow, muscular organ that is a reservoir for urine before it is excreted from the body
-The bladder is located in the anterior portion of the pelvic cavity behind the pubic symphysis. The average adult bladder stores more than one pint of urine
-The the stomach, the bladder is lined with rugae. These folds allow it to expand when full and contract when empty
107
urethra
is the tube extending from the bladder to the exterior of the body.
108
urinary sphincters
there are two, one located at either end of the urethra. These muscular rings control the flow of urine from the bladder into the urethra and out of the urethra through the urethral meatus.
109
Sphincter
is a ring-like muscle that closes a passageway
110
urethral meatus
also known as the urinary meatus, is the external opening of the urethra
111
meatus
means the external opening of a canal
112
female urethra
is approximately 1.5 inches long, and the urethral meatus is located between the clitoris and the opening of the vagina. In the female, the urethra transports only urine
113
male urethra
is approximately 8 inches long, and the urethral meatus is located at the tip of the penis. The urethra transports both urine and semen
114
prostate gland
which is part of the male reproductive system, surrounds the urethra. Most disorders of the prostate affect the male's ability to urinate.
115
urination
also known as voiding or micturition, is the normal process of excreting urine
-as the bladder fills up with urine, pressure is placed on the base of the urethra, resulting in the urge to urinate or micturate
-urination requires the coordinated contraction of the bladder muscles and relaxation of the sphincters. This action forces the urine through the urethra and out through the urethral meatus
116

127
chronic kidney disease (CKD)
also known as chronic renal disease, or kidney failure, is the progressive loss of renal function over months or years. This common condition, which can be life-threatening, may result from diabetes mellitus, hypertension, or a family history of kidney disease

is a genetic disorder characterized by the growth of numerous fluid-filled cysts in the kidneys. These cysts, which slowly replace much of the mass of the kidney, reduce the kidney function, which eventually leads to kidney failure
144
renal colic
is an acute pain in the kidney area that is caused by blockage during the passage of a nephrolith (kidney stone). Colic means spasms of pain in the abdomen. Renal colic pain sometimes comes in waves due to the peristaltic movement of the ureters

146
Stone
Also known as calculus, is an abnormal mineral deposit that has formed within the body and is named for the organ or tissue where it is located. These stones vary in size from small sand-like granules that pass through the body unnoticed to stone the size of marbles that can become lodged, causing acute pain
-The urinary system, stones form when waste products in the urine separate and crystallize. Normally, urine contains chemicals to prevent this from happening; however, dehydration and other factors may disrupt this balance
147
nephrolithiasis
describes the presence of stones in the kidney. As these stones travel with the flow of urine, they are named for the location where they become lodged

164
vesic/o
means bladder
165
neurogenic bladder
is a urinary problem caused by interference with the normal nerve pathways associated with urination. Normal urinary function depends on nerves to sense when the bladder is full and to control the muscles that either retain the urine or allow the bladder to empty
-depending on the type of neurological disorder causing the problem, the bladder may empty spontaneously, resulting in incontinence, which is discussed in a later section
-In contrast, the problem can prevent the bladder from emptying at all or from emptying completely. This can result in urinary retention with overflow leakage.
-Some of the causes of this condition are a tumor of the nervous system, trauma, neuropathy, or an inflammatory condition such as multiple sclerosis.
166

177
epispadias
is a congenital abnormality of the urethral opening. In the male with epispadias, the urethral opening is located on the upper surface of the penis. In the female with epispadias, the urethral opening is in the region of the clitoris
178
hypospadias
is a congenital abnormality of the urethral opening. In the male with hypospadias, the urethral opening is on the ventral surface (underside) of the penis. In the female with hypospadias, the urethra opens into the vagina
179
Urinary tract infection (UTI)
usually begins in the bladder; however, such an infection can affect all parts of the urinary system. These common infections are caused by bacteria, most often E. Coli, entering the urinary system through the urethra. They occur more frequently in women because the urethra is short and located near the opening of the rectum.
180

199
stress incontinence
is the inability to control the voiding of urine under physical stress such as running, lifting, sneezing, laughing, or coughing. This condition occurs more often in women than in men.
200
overactive bladder (OAB)
also known as urge incontinence, occurs when the muscles of the bladder contract involuntarily even though the bladder is not actually full enough to indicate the need to urinate. The urinary sphincters' relaxation in response to this urgent need to urinate may result in increased urinary frequency or accidental urination. This is a common condition in adults older than 40 and may be caused by excessive consumption of caffeine or alcohol, urinary tract infections, neurological diseases, or bladder or prostate problems
201
urinalysis
is the examination of urine to determine the presence of abnormal elements. These tests, which are used to diagnose diseases and pregnancy as well to detect the presence of substances such as drug
202
bladder ultrasound
is the use of a handheld ultrasound transducer to look for stones or for elevation for the bladder by an enlarged prostate after urination. A normal bladder holds between 300 and 400 mL of urine. When more than this amount is still present after urination, the bladder described as being distended, or enlarged.
203
urinary catherization
is the insertion of a tube into the bladder to procure a sterile specimen for diagnostic purposes. It is also used to drain urine from the bladder when the patient is unable to urinate for other reasons. Another use is to place medication into the bladder.
204
cystoscopy
is the visual examination of the urinary bladder with the use of a specialized type of endoscope known as a cystoscope.
205
endoscope
is an instrument used for visual examination of internal structures. A specialized cystoscope is also used for treatment procedures such as the removal of tumors or the reduction of an enlarged prostate gland
206
voiding cystourethrography
is a diagnostic procedure in which a fluoroscope is used to examine the flow of urine from the bladder and through the urethra. This procedure is often performed after cystography
207
computed tomography
also known as a CT scan, is more commonly used as a primary tool for evaluation of the urinary system because it can be rapidly performed and provides additional imaging of the abdomen, which may reveal other potential sources for the patient's symptoms
208
nephrotomography
is the use of a CAT scan to examine the kidneys
209
glomerular filtration rate (GFR)
is a blood test to check how well the kidneys are functioning at filtered blood. This test can help diagnose chronic kidney disease and kidney failure. The Blood urea nitrogen (BUN) test, also an indicator of kidney function
210
cystography
is a radiographic, or x-ray, examination of the bladder after a contrast medium is instilled via a urethral catheter. The resulting film is a cystogram
211
intravenous pyelography
also known as excretory urography, is a radiographic study of the kidneys and ureters. A contrast medium is administered intravenously to clearly define these structures in the resulting image, which is called an intravenous pyelogram (IVP). This test is used to diagnose changes in the urinary tract resulting from nephroliths, infections, enlarged prostate, tumors, and internal injuries after an abdominal trauma
212
KUB (Kidneys, ureters, bladder)
is a radiographic study without the use of a contrast medium.. This study, also referred to as a flat-plate of the abdomen, is used to detect bowel obstructions and nephroliths. Despite its name, a KUB x-ray odes not show the ureters
213
retrograde urography
is a radiograph of the urinary system taken after a contrast medium has been placed in the urethra through a sterile catheter and caused to flow upward through the urinary tract. Retrograde means moving backward
214
digital rectal examination
is performed on men by using a lubricated, gloved finger placed in the rectum to palpate the prostate gland to detect prostate enlargement and to look for indications of prostate cancer or tumors of the rectum. In this context, the term digital means using a finger. Palpate means the use of touch to examine a body part
215
prostate-specific antigen (PSA)
blood test used to screen for prostate cancer. This test measures the amount of prostate-specific antigen that is present in a blood specimen. The prostate-specific antigen is a protein produced by the cells of the prostate gland to help liquefy semen. The higher a mans' PSA level, the more likely cancer is present
216
diuretics
are medications administered to increase urine secretion, primary to rid the body of excess water and salt. Some foods and drinks, such as coffee, tea, and alcoholic beverages, also have a diuretic effect
-other drugs used to treat urinary tract problems including antibiotics for urinary tract infections and antispasmodics to block the signals that cause urinary incontinence
217
nutritional interventions
important dietary considerations for people with kidney disease include monitoring the amounts of sodium, potassium, protein, and phosphorus in their diet
218
dialysis
is a procedure to remove waste products, such as urea, creatinine, and excess water from the blood of a patient whose kidneys no longer function. The two types of dialysis in common use are hemodialysis an peritoneal dialysis. Patients can sometimes choose the type of long-term dialysis they prefer
219
hemodialysis
is the process by which waste products are filtered directly from the patient's blood. Treatment is performed on an external hemodialysis unit, sometimes referred to as an artificial kidney. Hemodialysis is the most common type of dialysis
220
shunt
implanted in the patient's arm is connected to the hemodialysis unit, the arterial blood flows through the filters of the unit. A shunt is an artificial passage that allows the blood to flow between the body and the hemodialysis unit
221
dialysate
dialysis filters contain this, which is a sterilized solution made up of water and electrolytes. This solution cleanses the blood by removing waste products and excess fluids
222
electrolytes
are the salts that conduct electricity and are found in the body fluid, tissue and blood
-the cleansed blood is returned to the body through a vein
-these treatments each take around 4 hours and must be repeated about three times a week. They can be done at a hospital, a dialysis clinic, or at home with the necessary equipment
223
peritoneal dialysis
is the lining of the peritoneal cavity acts as the filter to remove waste from the blood. The sterile dialysate flows into the peritoneal cavity around the intestine through a catheter implanted in the abdominal wall. This fluid is left in for a period of time to absorb waste products and then drained out through the tube
-the process is normally repeated several times during the day can be done using an automated system. This type of dialysis has some advantages; for example, it can be done at home by the patient. however, it is considered less effective than hemodialysis
224
continuous ambulatory peritoneal dialysis (CAPD)
provides ongoing dialysis as the patient goes about his or her daily activities. In this procedure, the dialysate solution is instilled from a plastic container worn under the patient's clothing. About every 4 hours, the used solution is drained back into this back and the bag is discarded. A new bag is then attached, the solution is instilled, and the process continues
225
continuous cycling peritoneal dialysis (CCPD) or automated peritoneal dialysis (APD)
uses a machine to cycle the dialysate solution during the night while the patient sleeps

231
renal transplantation,
commonly known as a kidney transplant, is the grafting of a donor, kidney, from either a living or nonliving donor, into the body to replace the recipient, although a tissue match increases the success rate. A single transplanted kidney is capable of adequately performing all kidney functions and frees the patient from the needs of dialysis
232
treatment of nephroliths
most small nephroliths (kidney stones) pass out of the urinary tract naturally over a period of two days to three weeks. This process can be quite painful and is sometimes accompanied by vomiting due to the pain. Larger stones may require surgical intervention
233
extracorporeal shockwave lithotripsy (ESWL)
is the most common kidney stone treatment. High-energy ultrasonic waves traveling through water or gel are used to break the stone into fragments, which are then excreted in urine. Extracorporeal means situated or occurring outside the body
-lithotripsy is also used to break up calculi in the ureter, bladder or urethra
234
percutaneous nephrolithotomy
is the surgical removal of the nephrolith through a small incision in the back. A small tube is temporarily inserted through the incision into the kidney. First urine is removed; then the stone is crushed and the pieces are removed. This procedure is used if ESWL has not been successful, if an infection is present, or if the stone is particularly large. Percutaneous means performed through the skin
235
ureterectomy
is the surgical removal of a ureter
236
ureterorrhaphy
is the surgical suturing of a ureter
237
ureteroscopy
is a treatment for a nephrolith lodged in the ureter. A specialized instrument called a ureteroscope is inserted through the urethra and bladder into the ureter. If possible, the nephrolith is removed intact through the scope. If the stone is too large, a laser is used to break it up and the pieces are then removed.
238
cystectomy
is the surgical removal of all or part of the urinary bladder. This procedure is usually performed to treat bladder cancer

244
urinary catheterization
also known as cathing, is performed to withdraw urine for diagnostic purposes, to allow urine to drain freely, or to place a fluid such as chemotherapy solution into the bladder.
245
indwelling catheter
remains inside the body for a prolonged time based on need. indwelling means residing within. This can be either a urethral or a suprapubic catheter
246
urethral catheterization
is performed by inserting a plastic tube called a catheter through the urethra and into the bladder
247
suprapubic catheterization
is the placement of a catheter into the bladder through a small incision made through the abdominal wall just above the pubic bone
248
foley catheter
is the most common type of indwelling catheter. This device is made of flexible tube with a balloon filled with sterile water at the end to hold it in place in the bladder. It is commonly used on post surgical patients and is named for its inventor, surgeon Frederic Foley
249
intermittent catheter
also known as a short-term catheter, is inserted as needed several times a day to drain urine from the bladder
250
meatotomy
is a surgical incision made in the urethral meatus to enlarge the opening
251
urethroplasty
is the surgical repair of damage of a defect in the walls of the urethra
252
urethrotomy
is a surgical incision into the urethra for relief of a stricture. A stricture is an abnormal narrowing of a bodily passage
253
ablation
is the term used to describe some types of treatment of prostate cancer. This treatment involves the removal of a body part or the destruction of its function through the use of surgery, hormones, drugs, heat, chemicals, electrocautery, or other methods. Electrocautery is the use of high-frequency electrical current to destroy tissue
254
prostatectomy
is the surgical removal of part or all of the prostate gland. This procedure is performed to treat prostate cancer or to reduce an enlarged prostate gland; however, this treatment can lead to erectile difficulties. A radical prostatectomy is the surgical removal of the entire prostate gland in cases where it is extremely enlarged or when cancer is suspected
255
transurethral prostatectomy (TURP)
is the removal of excess tissue from an enlarged prostate gland with the use of a resectoscope
256
resctoscope
is a specialized endoscopic instrument that resembles a cystoscope
257
retrograde ejaculation
is when an orgasm results in semen flowing backward into the bladder instead of out through the penis. This is the most common long-term complication of a TURP.
258
radiation therapy and hormone therapy
are additional treatments used to control prostate cancer. Watchful waiting is often the prescribed course of action in older patients because this disease normally progresses slowly
259
kegel exercises
named after Dr. Arnold Kegel, are a series of pelvic muscle exercises used to strengthen the muscles of the pelvic floor. They are used to control urinary stress incontinence in both sexes, in men to treat prostate pain and swelling, and in women to condition the muscles so that they will recover quickly after childbirth
260
bladder retraining
is behavioral therapy in which the patient learns to urinate on a schedule, with increasingly longer time intervals as the bladder increases its capacity. The goal is to reestablish voluntary bladder control and to break the cycle of frequency and urgency that results from urge incontinence

stage 3 - kidneys are moderately damaged
stage 4 - kidneys are severely damaged
stage 5 - esrd. This is complete kidney failure that requires dialysis or a kidney transplant to sustain the life of the patient

vascular assess
is the term used to describe the place on the body where blood flows from and returns to the body during hemodialysis.
293
arteriovenous (AV) fistula
is considered the "Gold standard" for vascular access. An AV fistula is a surgical connection between an artery and a vein that allows increased blood flow through the vein, which helps enlarge and strengthen the vein. An AV fistula allows a higher rate of blood to flow back and forth to a dialysis machine
