NCP Renal Failure : Chronic

Chronic renal failure (CRF) is the end result of a gradual, progressive loss of kidney function. Causes include chronic infections (glomerulonephritis, pyelonephritis), vascular diseases (hypertension, nephrosclerosis), obstructive processes (renal calculi), collagen diseases (systemic lupus), nephrotoxic agents (drugs, such as aminoglycosides), and endocrine diseases (diabetes, hyperparathyroidism). This syndrome is generally progressive and produces major changes in all body systems. The final stage of renal dysfunction, end-stage renal disease (ESRD), is demonstrated by a glomeruler filtration rate (GFR) of 15%–20% of normal or less.

TEACHING/LEARNING

May report: Family history of polycystic disease, hereditary nephritis, urinary calculus, malignancy History of DM (high risk for renal failure); exposure to toxins, e.g., nephrotoxic drugs, drug overdose, environmental poisons Current/recent use of nephrotoxic antibiotics, angiotensin-converting enzyme (ACE) inhibitors, chemotherapy agents, heavy metals, nonsteroidal anti-inflammatory drugs (NSAIDs), radiocontrast agents

Discharge plan

DRG projected mean length of inpatient stay: 5.9 days

May require alteration/assistance with medications, treatments, supplies; transportation, homemaker/maintenance tasks

Refer to section at end of plan for postdischarge considerations.

DIAGNOSTIC STUDIES

Urine:

Volume: Usually less than 400 mL/24 hr (oliguria) or urine is absent (anuria).

Color: Abnormally cloudy urine may be caused by pus, bacteria, fat, colloidal particles, phosphates, or urates.

Dirty, brown sediment indicates presence of RBCs, hemoglobin, myoglobin, porphyrins.

Specific gravity: Less than 1.015 (fixed at 1.010 reflects severe renal damage).

Osmolality: Less than 350 mOsm/kg is indicative of tubular damage, and urine/serum ratio is often 1:1.

Creatinine clearance: May be significantly decreased (less than 80 mL/min in early failure; less than 10 mL/min in ESRD).

Sodium: More than 40 mEq/L because kidney is not able to reabsorb sodium.

Protein: High-grade proteinuria (3–4+) strongly indicates glomerular damage when RBCs and casts are also present.

Blood:

BUN/Cr: Elevated, usually in proportion. Creatinine level of 12 mg/dL suggests ESRD. A BUN of >25 mg/dL is indicative of renal damage.

CBC: Hb decreased because of anemia, usually less than 7–8 g/dL.

RBCs: Life span decreased because of erythropoietin deficiency, and azotemia.

ABGs: pH decreased. Metabolic acidosis (less than 7.2) occurs because of loss of renal ability to excrete hydrogen and ammonia or end products of protein catabolism. Bicarbonate and PCO2 decreased.

Serum sodium: May be low (if kidney “wastes sodium”) or normal (reflecting dilutional state of hypernatremia).

Potassium: Elevated related to retention and cellular shifts (acidosis) or tissue release (RBC hemolysis). In ESRD, ECG changes may not occur until potassium is 6.5 mEq or higher. Potassium may also be decreased if patient is on potassium-wasting diuretics or when patient is receiving dialysis treatment.

Magnesium, phosphorus: Elevated.

Calcium/phosphorus: Decreased.

Proteins (especially albumin): Decreased serum level may reflect protein loss via urine, fluid shifts, decreased intake, or decreased synthesis because of lack of essential amino acids.

Serum osmolality: Higher than 285 mOsm/kg; often equal to urine.

KUB x-rays: Demonstrates size of kidneys/ureters/bladder and presence of obstruction (stones).

Retrograde pyelogram: Outlines abnormalities of renal pelvis and ureters.

Renal arteriogram: Assesses renal circulation and identifies extravascularities, masses.

Voiding cystourethrogram: Shows bladder size, reflux into ureters, retention.

Renal ultrasound: Determines kidney size and presence of masses, cysts, obstruction in upper urinary tract.

Renal biopsy: May be done endoscopically to examine tissue cells for histological diagnosis.

Renal endoscopy, nephroscopy: Done to examine renal pelvis; flush out calculi, hematuria; and remove selected tumors.

ECG: May be abnormal, reflecting electrolyte and acid-base imbalances.

X-ray of feet, skull, spinal column, and hands: May reveal demineralization/calcifications resulting from electrolyte shifts associated with CRF.
