Urinary Elimination Teresa V. Hurley, MSN, RN

Urinary System Kidneys filter nitrogen, metabolic wastes, excess ions and water Kidneys filter nitrogen, metabolic wastes, excess ions and water Urine produced at a rate of 60 mL/hour Urine produced at a rate of 60 mL/hour Bladder stores average 500 mL or more Bladder stores average 500 mL or more Void: detrusor muscle contracts and urine is pushed through internal urethral sphincter into urethra

Urinalysis Urine: clear, yellow, aromatic, without pathogens or parasites Urine: clear, yellow, aromatic, without pathogens or parasites Specific Gravity: (concentrate urine) Specific Gravity: (concentrate urine) Increases with dehydration Increases with dehydration Decreases with increased fluid intake Decreases with increased fluid intake

Urinalysis Abnormal Abnormal Protein: renal disease, 2 nd to exercise and stress Protein: renal disease, 2 nd to exercise and stress Glucose: elevated BS; diabetes Glucose: elevated BS; diabetes Ketones: CHO metabolism Ketones: CHO metabolism Diabetes, fever, fasting, starvation, high protein intake, vomiting, post-op Diabetes, fever, fasting, starvation, high protein intake, vomiting, post-op Hemoglobin: UTI, nephritis, trauma, lithiasis, hemolytic rx Hemoglobin: UTI, nephritis, trauma, lithiasis, hemolytic rx Bilirubin: liver disease Bilirubin: liver disease Urobilinogem: cirrhosis, heart failure, pernicious anemia, mono Urobilinogem: cirrhosis, heart failure, pernicious anemia, mono Nitrates: bacteria Nitrates: bacteria Leukocyte esterase: bacteria, fungal, parasitic, tumor, nephritis Leukocyte esterase: bacteria, fungal, parasitic, tumor, nephritis

Hematological Hematological BUN 8-16 mg/dL (end product protein metabolism) Creatinine mg/dL (muscle metabolism of creatin) Increased: renal failure, infection, obstruction, dehydration, increase protein intake, TPN Increased: renal failure, infection, obstruction, dehydration, increase protein intake, TPN Decreased: liver disease, decrease protein intake Decreased: liver disease, decrease protein intake

Factors Affecting Micturition Developmental considerations Developmental considerations Food and fluid intake Food and fluid intake Psychological variables Psychological variables Activity and muscle tone Activity and muscle tone Pathologic conditions Pathologic conditions Medication Medication

Developmental Considerations Children Children Toilet training 18 to 24 months, enuresis Toilet training 18 to 24 months, enuresis Effects of aging Effects of aging Nocturia, increased frequency, urine retention and stasis, voluntary control affected by physical problems Nocturia, increased frequency, urine retention and stasis, voluntary control affected by physical problems

Effects of Medications on Urine Production and Elimination Diuretics — prevent reabsorption of water and certain electrolytes in tubules Diuretics — prevent reabsorption of water and certain electrolytes in tubules Cholingeric medications — stimulate contraction of detrusor muscle, producing urination Cholingeric medications — stimulate contraction of detrusor muscle, producing urination Analgesics and tranquilizers — suppress CNS diminish effectiveness of neural reflex

Medications Affecting Color of Urine Anticoagulants — red color Anticoagulants — red color Diuretics — lighten urine to pale yellow Diuretics — lighten urine to pale yellow Pyridium — orange to orange-red urine Pyridium — orange to orange-red urine Elavil — green or blue-green Elavil — green or blue-green Levodopa — brown or black Levodopa — brown or black

Using the Nursing Process Assessing data about voiding patterns, habits, past history of problems Assessing data about voiding patterns, habits, past history of problems Physical examination of urinary system, skin hydration, urine Physical examination of urinary system, skin hydration, urine Correlation of these findings with results of procedures and diagnostic tests Correlation of these findings with results of procedures and diagnostic tests

Assessing a Problem With Voiding Explore its duration, severity, and precipitating factors. Explore its duration, severity, and precipitating factors. Note client’s perception of the problem. Note client’s perception of the problem. Check adequacy of client’s self-care behaviors. Check adequacy of client’s self-care behaviors.

Physical Assessment of Urinary Functioning Kidneys — check for costovertebral tenderness Kidneys — check for costovertebral tenderness Urinary bladder — palpate and percuss the bladder or use bedside scanner Urinary bladder — palpate and percuss the bladder or use bedside scanner Urethral meatus — inspect for signs of infection, discharge, or odor Skin — assess for color, texture, turgor, and excretion of wastes Urine — assess for color, odor, clarity, and sediment

Measuring Urine Output Ask client to void into bedpan, urinal, or specimen container in bed or bathroom. Ask client to void into bedpan, urinal, or specimen container in bed or bathroom. Pour urine into appropriate measuring device. Pour urine into appropriate measuring device. Place calibrated container on flat surface and read at eye level. Note amount of urine voided and record on appropriate form. Discard urine in toilet unless specimen is needed.
