Funct | |
Functions of the Kidney: | Urine formation, excretion of waste, regulation of: electrolytes, acid-base balance, RBC prod, cal/phos balance. Control of water and BP. Renal clearance, Synth of Vit D, Secretion of prostaglandins, activates growth hormone. |
Age-related changes in kidney function, such as decreased renal blood flow and glomerular filtration rate and thickening of the renal tubules can alter the excretion of drugs in older adults increasing | the risk of drug toxicity |
Decreased ability to concentrate urine maylead to increased susceptibility to | dehydration, further complicated by a deficit in thirst. |
Urine formation increases during the night when leg elevation promotes blood return to the heart and kidneys and may interrupt sleep patterns. Older persons may need to | drink more fluids throughout the day to allow for limiting their intake after the evening meal |
Nephrotox may occur with the admin of certain drugs and is potentially serious because it decreases | urinary excretion of the drug and increases the risk of drug toxicity. |

Risk Factor: Spinal cord injury | POSSIBLE RENAL OR UROLOGIC DISORDER: neurogenic bladder, uti, incontinence |
Frequency | frequent voiding, more than q3hours. Possible cause: infection, obstruction, anxiety, diuretics, BPH, urethral stricture, diabetic neuropathy |
Urgency | Strong desire to void. Possible cause: infection, chronic prostatitis, urethritis, obstruction, anxiety, diuretics, BPH, urethral stricture, diabetic neuropathy. |
Dysuria | Painful or difficult voiding. Possible cause: Lower UTI, inflammation of bladder or urethra, acute prostatitis, stones, foreign bodies, tumors in bladder |
Hesitancy | delay, difficulty in initiating voiding. Possible cause: BPH, compression of urethra, outlet obstruction, neurogenic bladder |
Nocturia | excessive urination at night. Possible cause: decreased renal concentrating ability, heart failure, diabetes, incomplete bladder emptying, excessive fluid intake, nephro syndrome, cirrhosis |
Incontinence | Involuntary losso f urine |
Enuresis | involuntary voiding during sleep |
polyuria | increased volume of urine voided |
oliguria | urine output less than 400mL/day |
anuria | urine output less than 50mL/day |
hematuria | RBC in urine. due to: cancer of genitourinary tract, acute glomerulonephritis, renal stones, renal tuber, blood dyscrasia, trauma, extremem exercise, rhematic fever, hemophilia |
proteinuria | abnormal amounts of protein in urine; due to: acute and chronic renal disease, nephrotic syndrome, vigorous exercise, heat stroke, severe heart failure, diabetic neuropathy, multiple myeloma |
Undergoing renal angiography | drink extra fluids on the day before. do not eat anyfood or fluids before the test. iv will be given. meds will be given for relaxation. local anesthesia. Expect burning sensation w/contrast media. Remain on strict bed rest 4-8hrs. Drink extra fluids. |
Normal urine flow rates: male | young adult: 21 middle aged: 12 older:9 |
Normal urine flow rates: female | young: 18 middle: 15 old: 10 |
needle renal biopsy | minimally invasive, renal tissue is removed through a needle, useful when CT or MRI findings are inconclusive. |
Fine-needle aspiration renal biopsy | minimally invasive, performed under local anesthesiain the OR, needle placement guided by fluoroscopy |
open renal biopsy | small incision made into flank, usually performed if needle biopsy tissue samples are not satisfactory. |
Normal urine color | yellow |
normal urine clarity | clear |
normal urine specific gravity | 1.003-1.029 |
normal urine osmolality | 50-1200 |
normal urine pH | 4.5-7.5 |
normal urine ketones | none |
normal urine protein | none |
normal urine glucose | none |
normal urine rbcs | 0-3 |
normal urine wbcs | 0-4 |
normal urine bilirubin | none |
Obtaining a clean-catch midstream urine specimen | wash hands. cleanse peepee area, begin voiding (hold labia apart ladies) into cup, and stop after 30-50mL. urinate the rest in the toilet! |
Dietary intake can affect urine characteristics as well as Urinary tract disorders and their mgmt. | A highproteine low carb diet can cause ketonuria. megadoses of vitamin c can interfere with certain lab tests, asparagus causes stinky pee and is a light diuretic. |
Diuretic therapy can result in | increased sodium, chloride, and magnesium levels with 24 hour urine electrolyte testing. |
Risk factors for acute pyelonephritis | instrimentation of the urethra and bladder, inability to empty bladder, prego, urinary stasis, urinary obstruction, diabetes mellitus, renal disease, neurogenci bladder, slutty ladies, men who take it up the booty. |
Risk factors for chronic pyelonephritis | recurrent episodes of acute pyelonephritis, chronic obstruction, reflux disorders (urine goes back UP) |
Urinary obstruction is the most common cause of pyelonephritis in the older adult. when present, the older adult may not experience the | fever and difficulty voiding common in younger adults. |
Urinalysis results with acute pyelonephritis | bacteria, leukocytes, casts, RBCs, low specific gravity, slightly alkaline pH, proteinuria, urine culture shows organism coloy count of >100,000 organisms |
Urinalysis results with chronic pyelonephritis | leukocytes, proteinuria, bacteria, casts, low specific gravity |
Use caution when giving drugs excreted by the kidney to those with renal disease. If the drug is deemed necessary, | it may be given in lower doses, observe the lclient closely for any changes in renal status. pay special attention to urinary output. |
Client and family teaching acute pyelonephritis | Consume acid forming foods such as meat, fish, poultry, eggs, grains, corn, lentils, and cranberries, prunes plums to prevent stone formation. avoid booze and coffee, show them how to do clean catch. have bp monitored, call doc for low back pain. |
