urethritis | inflammation of the urethra |
(PKD) polycystic kidney disease | inherited disease in which sacs of fluid called cysts develop int eh kidneys |
stent placement | insertion of a mesh tube into a natural passage conduit in the body to prevent, or counteract a disease-induced, localized flow constriction |
ureteral stent placement | insertion of a thin narrow tube into the ureter to prevent or treat obstruction of urine flow from the kidney |
enuresis | involuntary discharge of urine; also called incontinence |
nephrolith | kidney stone |
indwelling | left in place |
plasma | liquid portion of blood that is filtered by the nephrons to remove dissolved wastes |
nephrotic syndrome | loss of large amounts of plasma protein, usually albumin, through urine due to an increased permeability of the glomerular membrane |
(EMG) electromyography | measures the contraction of muscles that control urination using electrodes placed in the rectum and urethra |
dialysis | mechanical filtering process used to cleanse the blood of toxic substances, such as nitrogenous wastes, when kidneys fail to function properly |
electrolyte | mineral salt (sodium, potassium, or calcium) that carries an electrical charge |
renal nuclear scan | nuclear scan of the kidneys used to determine their size, shape, and position |
