What is Bladder Catheterization and Definition

The insertion of a narrow, flexible tube into the BLADDER through the URETHRA to drain URINE from the body. Bladder catheterization may be necessary to collect an uncontaminated (sterile) urine sample or to drain urine from the bladder. The catheter placement may be short term, such as after surgery or during serious illness, or long term, such as when STROKE, PARALYSIS, or other condition results in loss of bladder control (complete URINARY INCONTINENCE).

Long-term catheterization may be intermittent, in which the caregiver periodically inserts the catheter to drain collected urine and then removes the catheter, or indwelling (often called a Foley catheter), in which the catheter remains tethered in the bladder (a small inflatable balloon at the tip of the catheter keeps the catheter from sliding out of the urethra). An indwelling catheter drains into a collection bag which the person or caregiver empties frequently and regularly. A caregiver must replace an indwelling catheter every four to six weeks for hygienic reasons. Many people who have indwelling catheters or who use long-term intermittent catheterization take ANTIBIOTIC PROPHYLAXIS to prevent URINARY TRACT INFECTION (UTI). Bladder catheterization greatly increases the risk for UTI. Proper hygiene is essential when inserting and removing a bladder catheter and when an indwelling catheter is in place.

Aging, urinary system changes that occur with

The Urinary System |

At birth the structures of the urinary system are fully developed and function under the automatic control of the NERVOUS SYSTEM. The newborn’s KIDNEYS filter BLOOD and make URINE. The BLADDER collects the urine and, when it fills to a point that triggers the micturition REFLEX, it empties to drain urine via the URETHRA to outside the body. Voluntary

Albuminuria - definition, causes symptoms and treatment

The Urinary System |

Excessive excretion of ALBUMIN, a form of protein, into the URINE. Albuminuria, also called proteinuria, typically indicates kidney conditions that affect the glomeruli (the tubular structures within the KIDNEYS that filter wastes and excess water from the BLOOD to excrete in the urine). Such conditions include GLOMERULONEPHRITIS, GLOMERULOSCLEROSIS,

Alport’s Syndrome - symptoms and treatment

The Urinary System |

What is Alport’s Syndrome An inherited genetic disorder in which one, two, or three mutations occur in the GENE that encodes type IV collagen formations, also called basement membranes. The mutations affect up to three of the six protein chains (alpha-3, alpha-4, and alpha-5) that make up type IV collagen, which is a foundation for a number of

Anuria - what is, define, definition

The Urinary System |

What is Anuria and Definition Anuria - The failure to produce URINE. Numerous circumstances can result in anuria, from severe DEHYDRATION and severe HYPOTENSION (low BLOOD PRESSURE) to END-STAGE RENAL DISEASE (ESRD) and RENAL FAILURE. Anuria requires prompt medical evaluation to determine and remedy the underlying cause. Without such correction, waste

Bladder - what is, definition, function, diseases and urination

The Urinary System |

What is Bladder and Definition A muscular, saclike structure in the lower pelvis that serves as a reservoir for the URINE the KIDNEYS produce. In women the bladder is in front of and slightly below the UTERUS. During PREGNANCY the expanding uterus limits the bladder’s ability to expand, accounting for the URINARY FREQUENCY common in pregnancy’s

Uremia - definition, signs, symptoms and treatment

The Urinary System |

What is Uremia and Definition Uremia is a serious condition in which nitrogenbased toxins such as urea and creatinine, the primary waste products of METABOLISM, accumulate in the BLOOD because the KIDNEYS are unable to filter them out and pass them from the body via the URINE. Uremia indicates RENAL FAILURE. Urologists sometimes use the term azotemia to

Ureter function and definition

The Urinary System |

Ureter, in a human organism, is a muscular tube, fairly thick and rigid, that leads URINE from the kidney to the urinary BLADDER. Both of the two tubular structures arise from the renal pelvis and collect the urine from the kidney’s collecting tubules. Both ureters with the inner diameter of 3 or 4 millimeters exit the kidney at the hilus. Then, the

Urethra function and definition

The Urinary System |

A narrow, somewhat muscular tube that carries URINE from the BLADDER to the outside of the body. The point of exit is the urinary or urethral meatus. The urethral sphincter MUSCLE at the base of the bladder controls the release of urine into the urethra. Once the urethral sphincter relaxes to let urine pass, the urine flows to the outside of the body until

Urethral stricture - symptoms, diagnosis and treatment

The Urinary System |

What is Urethral Stricture Narrowing of the URETHRA, impeding the passage of URINE from the BLADDER to the outside of the body. Urethral stricture may be congenital (present at birth) or acquired such as through scarring resulting from repeated URETHRITIS, BLADDER CATHETERIZATION, and other irritations to the urethra. BENIGN PROSTATIC HYPERPLASIA (BPH) and

Urethritis - in woman/men - symptoms and treatment

The Urinary System |

What is Urethritis and Definition INFLAMMATION of an URETER. INFECTION, typically a sexually transmitted disease (STD), is the most common cause of urethritis though urethritis may occur as a result of inflammation or irritation from trauma such as occurs with BLADDER CATHETERIZATION or CYSTOSCOPY. Traumatic urethritis improves rapidly when the source of
