Pyelonephritis
|
|
Pyelonephritis Infection of the kidneys. A severe infection favoured by a slowing in the flow of urine (urinary stasis) between the kidney and bladder, through a long duct called the urethra. This stasis is naturally increased by pregnancy (atonicity of ducts), but the absence of any blockage in the urinary tract or reflex from the bladder and urethras (vesicourethral reflux) should be ascertained.
RELATED TERMS--------------------------------------
Infection
Anything that invades the body and reproduces. Infections can be bacteria, protozoa, fungi, or viruses. Bacteria and fungi are one celled creatures that cause many infections including strep throat, bladder infections, and some lung infections. Fungi cause “athlete’s foot” and thrush, an infection in the mouth. Protozoa are small organisms with many cells that can cause infections in the guts or in the lungs. Most healthy people do not get protozoal infections, but people with suppressed immune systems can. Viruses are not really organisms; they are tiny particles that can live only inside another cell. They reproduce by taking over a cell and causing that cell to make more virus particles, rather than doing what the cell is supposed to do. Viruses cause most colds and flu cases.
Urine
The waste fluid secreted by the kidneys, transported by the ureters, stored in the bladder, and voided through the urethra.
Kidney
One of the paired organs that excrete urine. The kidneys are bean-shaped organs (about 11 cm long, 5 cm wide, and 3 cm thick) lying on either side of the vertebral column, posterior to the peritoneum, about opposite the twelfth thoracic and first three lumbar vertebrae.
Bladder
A muscular triangular-shaped, hollow organ located in the pelvic cavity and supported by the pelvic floor muscles. The bladder stretches to store urine and contracts to release urine.
Duct
A channel or passage through which fluids move.
Urethra
A narrow tube that transports urine from the bladder to the outside of the body. In males, it also conducts sperm and semen to the outside.
Reflex
An automatic, involuntary movement.
SIMILAR TERMS--------------------------------------
Pyelitis
Inflammation of the urine-collecting system within the kidney.
PREVIOUS AND NEXT TERMS--------------------------------------
Photoreceptor
A light sensitive neuron. Photoreceptors interact with light which produces changes in their electrical properties which are communicated to other neurons. They constitute the first stage in the physiological process which underlies vision. The human retina, like the retina of most vertebrates, contains two broad classes of photo-receptors, rods and cones.
Paternity test
A test based on blood groups to determine whether a particular man could be the biological father of a particular child; negative results prove he was not the father but positive results show only that he could be.
Penis
The male sex organ, which consists of a head called glans, and the shaft or body. At the tip of the glans is the urethral opening, through which urine and semen leave the body. The shaft or the body of the penis is made of spongy tissue and blood vessels. And it fills with blood an grows in size (becomes erect) during sexual excitement.
Penis enlargement treatment
Treatments aimed at increasing penile length or girth also known as penile augmentation. They can be either non-surgical treatment or surgical treatments.
Phentermine
A sympathomimetic amine used in attack preparations as a vasoconstrictor and bronchodilator, usually in combination with an antihistamine drug. An appetite suppressant that disrupts the transmission of signals from the neurotransmitters and is used in the management of obesity.
Pyelonephritis
Panic disorder
Panic disorder is a condition in which persons experience sudden, severe attacks of anxiety. Symptoms consist of heart palpitations, shortness of breath, sweating, dizziness, upset stomach and fear of dying or losing control. Some patients have such attacks only occasionally, while others may have several attacks a day. Since the attacks are very frightening, many patients start to avoid situations in which the attacks have occurred, such as driving on an expressway or over bridges, shopping in large department stores or malls, etc. Agoraphobia is the term for such avoidance, which in severe cases can lead to being completely housebound.
Paresis
It is only an impairment of the action of a muscle or a group of muscles (not a total loss of function).
Paraplegia
Paraplegiai nvolves a loss of sensation and movement in the legs and in part or all of the trunk. This varies according to the level of the injury. Generally, the lower the injury, the less the loss of movement and sensation. Paraplegia usually results from an injury to the spinal cord in the mid and lower back.
Post-traumatic stress disorder (PTSD)
A syndrome caused by re-experiencing traumatic events while being unaware of or unresponsive to current events or, in other words, a "flashback." A child may experience sleeping problems, nightmares, intrusive thoughts, have difficulty concentrating, self-destructive behavior, hyperactivity or anxiety/panic disorder. Therapy is crucial in managing PTSD.
Presbyopia
The eye's gradually decreasing ability to focus on nearby objects. Presbyopia is a normal part of aging and affects virtually everyone, usually becoming noticeable after age 40. People with presbyopia typically hold reading materials at arm's length in order to bring the words into focus. They may experience headaches or eyestrain while reading, viewing a computer screen, or doing close work. Presbyopia can be corrected with reading glasses, bifocal or variable focus lenses, or contact lenses. Using bright, direct light when reading is also helpful.
