Term | Definition |
---|---|
anagelsic | drug that relieves pain |
straight catherer | a type cathater that is inserted through the urethra into the bladder to relieve urinary retention or to collect a sterile, specimen of urine for testing; the catheter is removed immediately after the procedure |
suprapubic catheter | indwelling catheter inserted directly in the bladder through an abdominal incision above the pubic bone that includes a collection system that allows urine to be drained into a bag; used in patients requiring long-term catheterization |
Foley catheter | indwelling catheter inserted through the urethra and into the bladder that includes a collection system allowing urine to be drained into a bag; the catheter can remain in place for an extended period |
kidney dialysis | methods of filtering impurities from the blood, replacing the function of one or both kidneys lost in renal failure |
hemodialysis | method of removing impurities by pumping the patient's blood through a dialyzer, the specialized filter of the artificial kidney machine (hemodialyzer) |
peritoneal dialysis | method of removing impurities using the peritoneum as the filter; a catheter inserted in the peritoneal cavity delivers cleansing fluid (dialysate) that is washed in and out in cycles |
renal transplantation | transfer of a kidney from the body of one person (donor) to another (recipient) |
urinary diversion | crenation of a temporary or permanent diversion the urinary tract to provide a new passage through which urine exists the body; used to read defects or diseases (e.g. bladder, cancer) |
noncontinent ileal conduit (type of urinary diversion) | removal of portion of the ileum to use as a conduit to which the ureters are attached at one end; the other end is brought through the opening (stoma) created in the abdomen, urine cannot be held and drains continuall |
continent urostomy | internal reservoir (pouch) from segment of intestine that diverts urine through opening (stoma) & then brought through abdominal wall; valve created internally to prevent leakage, patient empties pouch by catheterization |
continent | the ability to hold/retain urine |
orthotopic bladder (neobladder) | artificial bladder, placed at the site of the excised bladder, constructed from portions of intestine connected to the urethra, allowing "natural" voiding also called "neobladder" |
extracorporeal shock wave lithotripsy (ESWL) | procedure using ultrasound outside the body to bombard and disintegrate a stone within; most commonly used to treat urinary stones above the bladder |
nephrotomy | incision into the kidney |
nephrorrhaphy | suture of an injured kidney |
nephrolithotomy | incision into the kidney for the removal of stones |
nephrectomy | excision of a kidney |
pyeloplasty | surgical reconstruction of the renal pelvis |
stent placement | use of a device to hold open vessels or tubes |
intracorporeal lithotripsy | method of destroying stones with the urinary tract using discharges of electrical energy that are transmitted to a probe within a flexible endoscope; most commonly used to pulverize bladder stones |
rectoscope | urologic endoscope inserted through the urethra to reset (cut and remove) lesions of the bladder, urethra, or prostate |
urologic endoscopic surgery | use of specialized endoscopes (e.g., resectoscope) within the urinary tract to perform various surgical procedures, such as resection of a tumor, repair of an obstruction, stone retrieval, placement of a stent, etc. |
blood urea nitrogen (BUN) | blood test that measures the amount of urea in the blood; a hun BUN indicates the inablity of one or both kidneys to excrete urea |
creatinine, serum | test to determine the level of creatinine in the blood; useful in assessing kidney function |
creatinine, urine | test to determine the level of creatinine in the urine |
creatinine clearance testing | measurements of the level of creatinine in the blood and in a 24-hour urine specimen to determine the rate at which creatinine is "cleared" from the blood by the kidneys |
urine culture and sensitivity (C&S) | isolation of a urine specimen in a culture medium to propagate the growth of microorganisms; organisms that grow in the culture are identified, as are drugs to which they are sensitive |
microscopic findings | microscopic identification of abnormal constituents in the urine (e.g. bacteria , red blood cells, white blood cells and casts) |
glucose | chemical test used to detect sugar in the urine; most often used to screen for diabetes |
Albumin | chemical test used to detect the presence of albumin ( a type of protein) in the urine |
protein | chemical test used to detect the presence of protein (A nitrogenous compound) in the urine |
