|
Urinalysis |
Urine culture may be done to confirm suspected infection, to identify causative organisms, and to determine appropriate antimicrobial |
|
|
Urine Specific gravity |
To determine the specific gravity of urine. The density of a urine sample is compared with water. Indicates hydration status and gives information about the kidneys ability to concentrate urine. Normal range is 1.003 - 1.030 Lower ranges more dilute Higher ranges more concentrate |
|
|
Blood Urea Nitrogen (BUN) |
Is a lab test used to determine the kidneys ability to rid the blood of NPN waste and urea which result in protein breakdown. Assesses the overall function of the kidneys, monitors progression of kidney disease, and evaluated the effectiveness of therapies. Normal BUN is 10 - 20mg **NPO 8 hours bf test |
|
|
Blood Creatinine |
Used to to diagnose impaired kidney function Not affected by dehydration, malnutrition or hepatic functions Normal acceptable range is 0.6 to 1. mg |
|
|
Creatinine Clearance |
Levels are related directly to muscle contraction and then excreted by glomerular filtration. Measured for 24 hour period During test pt avoids physical activity. 24 hour urine and fasting blood serum at onset and conclusion An elevated serum level with a decline in urine level indicates renal disease. Normal ranges are serum 0.6 to 1.1 (female) 0.7 to 1.3 (male) Urine 88 to 128 (female) 97 to 137 (male) |
|
|
Prostate Specific Antigen (PSA) |
Normal range is less than 4! Older men have higher levels. Used to evaluate prostate health of men being treated for prostate cancer. Elevated levels can be prostate cancer, infection, inflammation or a recent cystoscopy. Elevations warrant additional tests for prostate cancer. Is not a definitive test for cancer. |
|
|
Urine Osmolality |
Directly determines the number of particles per volume of water. Results provide info |
|
|
Kidney Ureter bladder radiography |
Assesses general status of the abdomen and size structure and position. No special prep. Abnormal findings tumors, calculi, glomerulonephritis, cysts, and other conditions |
|
|
IV pyleography or IV urographh |
Evaluates structures of the urinary tract filling of the renal pelvis with urine and transport of urine via ureters to the bladder ***dye allergic reaction NPO 8 hours and laxative May find hydronephroses (swelling kidney) calculi, pKD and tumors |
|
|
Retrograde pyelography |
Examines the lower urinary tract with a cystoscope under aseptic. Retrograde dye injected through an in dwelling catheter into the bladder to evaluate its structure or to determine the cause of recurrent infections |
|
|
Voiding cystourethrography |
Preparations includes administering an enema bf the test! Pt asked to void while radiographs are being taken |
|
|
Endoscopic procedures |
Visual examinations of hollow organs down with a scope (with light and tube! Signed written consent is necessary. The procedure is performed urologist. |
|
|
Renal angiography |
Helps evaluate blood supply to the kidneys assess masses and detects possible complications after kidney transplantation. Withhold oral intake the night bf. Procedure is passing a small catheter into the femoral artery and injecting dye. Pt must lie flat in bed several hours for risk of bleeding. Assess puncture site for hematoma or bleeding. Assess circulatory status of the extremity every 15 mins for 1 hour then very 2 hours for 24 hours |
|
|
Renal Venography |
Provides info about the kidneys venous drainage. Catch is inserted into fem vein. After care: assess vital signs, monitor for bleeding at puncture site, assess for bruising and swelling, assess distal pulses. |
|
|
Renal Scan |
Radionuclide tracer substance that will take up by renal tubular cells renal tubular cells or excreted by glomerular filtrate in injected IV Check facility policy for disposal of pt urine for 24hr and no pregnant nurses! |
|
|
Renal biopsy |
Kidney is biopsies via needle biopsy also called percutaneous biopsy. Bed rest for 24 hours after the procedure. Gradual return to activities in 48-72 hours. Watch for infection |
|
|
Urodynamic Studies |
Is indicated when neurological disease is thought to be underlying cause of incontinence. |
