Urinary System

The urinary system which is also called the renal system is the system that stores, produces, and eliminates urine.

It includes the two kidneys, bladder, two ureters, and the urethra.

How it’s formed

Urine is formed in the kidney’s through blood filtration.

The urine is then passed through the ureters and to the bladder where it is stored.

During urination the urine is then passed from the bladder to the urethra then outside the body.

Functions

Removal of waste from the body. Regulate electrolytes. Regulation of acid- base homeostasis. Controlling blood volume and blood

pressure.

• The urethra is longer than the females.

• Females can get infections easier because of the proximity to the vagina.

• Males though share their reproductive organ with the urinary track.

• Males can et infections due to it’s closeness to the prostate.

Kidneys

•The kidney’s filter the impurities in the urine and sends back certain nutrients the body needs to function.

•The rest of the waste from the kidney’s continue it’s path to the ureters and it is stored in the bladder.

Diseases/Infections

Any mishap in this system may disrupt the normal functioning of the body, resulting in several kinds of disorders, and discomfort. There is a wide range of urinary system diseases, which people suffer from:

- Cystitis Cystitis is inflammation of the bladder, specifically,

inflammation of the wall of the bladder. Cystitis usually occurs when the urethra and bladder,

become infected by bacteria and the area becomes irritated and inflamed.

Cystitis is a fairly common lower urinary tract infection, which affects people of both sexes and all ages. It is more common among females than males.

Diseases/Infections

What causes Cystitis? - When women insert a tampon there is a slight risk of bacteria entering the

urethra.  When a urinary catheter is changed there may be damage to the area.  There is a higher incidence of cystitis among women who use the diaphragm

for contraception, compared to sexually active women who doesn’t  Frequent and/or vigorous sex increases the chances of physical damage or

bruising, which in turn makes the likelihood of cystitis developing higher.  Sexually active women have a higher risk of bacteria entering via the urethra.  Part of the urinary system may be blocked.  During the menopause women produce less mucus in the vaginal area. This

mucus stops the bacteria from multiplying.  During the menopause the lining of a woman's urethra gets thinner as her

levels of estrogen drop. The thinner the lining becomes, the higher the chances are of infection and damage. 

A woman's urethra opening is much nearer the anus than a man's. Consequently, there is a higher risk of bacteria entering the urethra from the anus.

Breakdown of Cystitis

Symptoms of Cystitis

Urine may have traces of blood Urine is dark and/or cloudy Urine has a strong smell Pain just above the pubic bone Pain in the lower back Pain in the abdomen Only small amount of urine is passed each time Frequent need to urinate Burning sensation when urinating Older women may feel weak and feverish but have none of

the other symptoms mentioned above When children have cystitis they may have any of the

symptoms listed above, plus vomiting and general weakness.

Urethritis•The inflammation of the Urethra.

•It’s mainly cause by bacteria that enters the urethra from skin around the urethras' opening.

•Causes: E. coli and other bacteria present in stool.Gonococcus. It is sexually transmitted and causes gonorrhea.Chlamydia trachomatis. It is sexually transmitted and causes Chlamydia.The herpes simplex virus (HSV-1 and HSV-2) can also cause urethritis. Trichomonas is another cause of urethritis. It is a single-celled organism that is sexually transmitted.

Urethritis Symptoms

Feeling the frequent or urgent need to urinate

Difficulty starting urination Urethritis can also cause itching, pain, or

discomfort when a person is not urinating. Pain during sex Discharge from the urethral opening or

vagina In men, blood in the semen or urine

Bladder Stones

Bladder stones are usually small masses of minerals that form in your bladder. Bladder stones develop when urine in your bladder becomes concentrated, causing minerals in your urine to crystallize. Concentrated, stagnant urine is often the result of not being able to completely empty your bladder. This may be due to an enlarged prostate, nerve damage or recurring urinary tract infections.

  Some people with bladder stones have no problems — even when their stones are

large. But if a stone irritates the bladder wall or blocks the flow of urine, signs and symptoms can develop.

 Symptoms Lower abdominal pain In men, pain or discomfort in the penis Painful urination Frequent urination, especially during the night Difficulty urinating or interruption of urine flow Blood in your urine Cloudy or abnormally dark-colored urine

Glomerulonephritis

It’s the inflammation of the tiny filters in your kidneys. Glomeruli remove excess fluid, electrolytes and waste from your bloodstream and pass them into your urine. Also called glomerular disease, glomerulonephritis can be acute meaning a sudden attack of inflammation, or chronic; coming on gradually.

Signs and Symptoms of Glomerulonephritis

Pink or cola-colored urine from red blood cells in your urine (hematuria)

Foamy urine due to excess protein (proteinuria) High blood pressure (hypertension) Fluid retention (edema) with swelling evident in your face, hands, feet

and abdomen Fatigue from anemia or kidney failure An elevated body temperature (typically about 100.4F) Breathing difficulties Edema (swelling), especially in the hands, face, feet, ankles or

abdomen Loss of appetite Nausea Pallor Vision problems Vomiting

Urinary Incontinence

It’s a loss of bladder control. Some people who suffer from this disorder, might get a strong urge to urinate but they cannot make it to the washroom in time. While, some may suffer from leaking the urine by merely coughing or sneezing. Causes could be several, common ones include medical conditions such as constipation or urinary tract infection. Temporary cases may be caused by drinking alcohol, drinking too much fluids, irritated bladder, and medications. Cases which are chronic could be a result of pregnancy, enlarged prostate, prostate cancer, bladder stones, and aging.

SymptomsThere are five different types of urinary inconsistence

1. Stress incontinence. This is loss of urine when you exert pressure — stress — on your bladder by coughing, sneezing, laughing, exercising or lifting something heavy. Stress incontinence occurs when the sphincter muscle of the bladder is weakened. In women, physical changes resulting from pregnancy, childbirth and menopause can cause stress incontinence. In men, removal of the prostate gland can lead to stress incontinence.

2. Urge incontinence. This is a sudden, intense urge to urinate, followed by an involuntary loss of urine. Your bladder muscle contracts and may give you a warning of only a few seconds to a minute to reach a toilet. With urge incontinence, you may need to urinate often, including throughout the night. Urge incontinence may be caused by urinary tract infections, bladder irritants, bowel problems, Parkinson's disease, Alzheimer's disease, stroke, injury or nervous system damage associated with multiple sclerosis. If there's no known cause, urge incontinence is also called overactive bladder.

3. Overflow incontinence. If you frequently or constantly dribble urine, you may have overflow incontinence, which is an inability to empty your bladder. Sometimes you may feel as if you never completely empty your bladder. When you try to urinate, you may produce only a weak stream of urine. This type of incontinence may occur in people with a damaged bladder, blocked urethra or nerve damage from diabetes, multiple sclerosis or spinal cord injury. In men, overflow incontinence can also be associated with prostate gland problems.

4. Mixed incontinence. If you experience symptoms of more than one type of urinary incontinence, such as stress incontinence and urge incontinence, you have mixed incontinence.

5. Functional incontinence. Many older adults, especially people in nursing homes, experience incontinence simply because a physical or mental impairment keeps them from making it to the toilet in time. For example, a person with severe arthritis may not be able to unbutton his or her pants quickly enough. This is called functional incontinence.

Enlarged Prostate Gland (Males)

Prostate gland enlargement is a common condition as men get older. Also called benign prostatic hyperplasia (BPH) and prostatic hypertrophy, prostate gland enlargement can cause bothersome urinary symptoms. Untreated prostate gland enlargement can block the flow of urine out of the bladder and can cause bladder, urinary tract or kidney problems
