medulla the most internal part of a structure or organ
meatus an opening or tunnel through any part of the body,as in the urinary meatus, which is the external opening of the urethra
hydroureter the distension of the ureter with urine due to blockage from an obstruction
hydrostatic pressure the pressure exerted by a liquid
hilum the depression, or pit of an organ where the vesels and nerves enter
glomerulus a ball shaped collection of very tiny coiled and intertwined capillaries located in the cortex of the kidney
glomerular filtrate substances that filter out of the blood through the thin walls of the glomeruli
fossa a hollow or depression,especially on the surface of the end of a bone. in the kidney transplantation the donor kidney is surgically placed in the iliac fossa of the recipient
dwell time length of time the dialysis solution stays in the peritoneal cavity during peritoneal dialysis
dialysis the process of removing waste products from the blood when the kidneys are unable to do so
dialystate solution that contains water and electrolytes that passes through the artificial kidney remove excess fluids and wastes from the blood;also known as "bath"
urethritis inflammation of the urethra. urethritis characterized by dysuria is usually the result of an infection of the bladder or kidneys
urethra a small tubular structure that drains urine from the bladder to the outside of the body
ureter one of a pair of tubes that carries urine from the kidney to the bladder
toxic poisonous
turbid cloudy
uremia the presence of excessive amounts of urea and other nitrogenous waste products in the blood;also called azotemia
voiding the act of eliminating urine from the body;also called micturition or urination
vesticocele herniation or downward protrusion of the urinary bladder through the wall of the vagina;also called a cystocele
urine the fluid released by the kidneys,transported by the uterus,retained in the bladder & is eliminated through the urethra. normal urine is clear,straw colored and slighly acid
urination the act of eliminating urine from the body;also called micturition or voiding
albuminuria the presence in the urine of abnormally large quantities of protein,usually albumin
anuria the cessation (stopping) of urine production or a urinary output of less than 100 ml per day
hematuria abnormal presence of blood in the urine
glycosuria abnormal presence of a sugar,especially glucose in the urine
freguency the # of repetitions of any phenomenon within a fixed period of time such as the # of heartbeats per minute;in the case of urinary freq.,urination at short intervals without increase in the daily vol of urinary output due 2 reduced bladder capacity
fatigue a state of exhaustion of loss of strength or endurance such as may follow sternuous physical activity
enuresis a condition of urinary incontinence especially at night in bed;bedwetting
dysuria painful urination
bacteriuria the presence of bacteria in the urine
urgency a feeling of the need to void urine immediatley
pyuria the presence of an excessive number of white blood cells in the urine,usually a sign of an infection of the urinary tract;pus in the urine
polyuria excretion of abnormally large amounts or urine
oliguria secretion of a diminished amount of urine in relation to the fluid intake;scanty urine output
nocturia urination,especially excessive at night also called nocturia
malaise a vague feeling of bodily weakness or discomfort often making the onset of disease or infection
lethargy the state or quality of being indifferent, apathetic (without emotion) or sluggish
ketonuria presence of excessive amounts of ketone bodies in the urine
cystitis inflammation of the urinary bladder
glomerulonephritis (acute) an inflammation of the glomerulus of the kidneys
hydronenephrosis distension of the pelvis and calyces of the kidney caused by urine that cannot flow past an obstruction in a ureter
renal calcui stone formation in the kidney
pyelonnephritis (acute) a bacterial infection of the renal pelvis of the kidney
polycystic kidney disease a herditary disorder of the kidneys in which grapelike fluid-filled sacs or cysts replace normal kidney tissue
nephrotic syndrome a group of clinical symptoms occurring when damage to the glomerulus of the kidney is present and large quantities or protein are lost through the glomeruluar membrane into the urine resulting in severe proteinuria(nehhrosis)
vesicoureteral reflux an abnormal backflow(reflux) of urine from the bladder to the ureter
renal failure, chronic (uremia) progressively slow development of kidney failure occurring over a period of years. the late stages of chronic renal failure are known as end-stage renal disease(esrd)
renal cell carcinoma a malignant tumor of the kidney occurring in adulthood
peritoneal dialysis mechanical filtering process used to cleanse the blood of waste products,draw off excess fluids, & regulate body chemistry when the kidneys fail to function properly
wilm's tumor a malignant tumor of the kidney occurring predominately in childhood
hemodialysis the process of removing excess & toxins from the blood by continually shunting the patients blood from the body into a dialysis machine for filtering & then returning the clean blood 2 the patients bloodstream
kidney transplantation involves the surgical implantation of a healthy human donor kidney onto the body of a patient with irreversible renal failure.kidney function is restored with a successful transplant & the patient is no longer dependent on dialysis
blood urea nitrogen (bun) blood test performed to determine the amount of urea and nitrogen (waste products normally excreted by the kidney)present in the blood
catheterization the introduction of a catheter (flexible hollow tube) into a body cavity or organ to instill a substance or to remove a fluid
creatinine clearance test a diagnostic test for kidney function that measures the filtration rate of creatinine, a waste product (of muscle metabolism)normally removed by the kidney
cystometrography an examination performed to evaluate bladder tone;measuring bladder pressure during filing and voiding
urine culture a procedure used to cultivate the growth of bacteria present in a urine specimen for proper microscopic identification of the specific pathogen (disease producing microorganism)
renal scan a procedure in which a radioactive isotope(tracer)is injected intravenously & the radioactivity over each kidney is measured as the tracer passes through the kidney
retograde pyelogram (rp) radiographic procedure in which small-caliber catheters are passed through a cystoscope into the ureters to visualize the ureters and the renal pelvis
clean catch specimen this collection is used to avoid contamination of the urine specimen from the microorganisms normally present on the external genitalia
24 hour urine specimen a collection of all of the urine excreted by the individual over a 24 hr period.the urine is collected on one large container.this urine specimen is also called composite urine specimen
