Polycystic kidney disease

Growth of multiple, bilateral, grapelike clusters of fluid-filled cysts in the kidneys
May progress slowly even after symptoms of renal insufficiency appear
Adult form, which has an insidious onset but usually becomes obvious between ages 30 and 50, has autosomal dominant inheritance
Usually fatal within 4 years of uremic symptom onset, unless dialysis begins
Carries a widely varying prognosis in adults
Also known as PKD and autosomal dominant polycystic kidney disease (ADPKD)
Cysts enlarge the kidneys, leading to thickening of the basement membranes in the tubules, macrophage infiltration, neovascularization, fibrosis, and cystic dilation of the renal tubules, and ultimately resulting in the compression and eventual replacement of functioning renal tissue. (See Polycystic kidney.)
Renal deterioration results.
The condition progresses relentlessly to fatal uremia.
Autosomal dominant form inherited as an autosomal dominant trait (ADPKD), affecting the short arm of chromosome 16 and the long arm of chromosome 4
Acquired (more than one-half of patients receiving dialysis for more than 3 years)
The disease affects both sexes equally, with a slight increase in severity of the disease in men.
Autosomal dominant form accounts for 6% to 10% of all cases of end-stage renal disease in the United States.
The usual age of onset for the autosomal form typically ranges from age 20 to 40.
Cyst rupture
Hepatic failure
Cerebral aneurysm, subarachnoid hemorrhage
Mitral valve prolapse
Metabolic abnormalities
Renal calculi
Renal failure
Respiratory failure
Heart failure
Recurrent hematuria
Life-threatening retroperitoneal bleeding
Family history
Urinary tract infections
Pain in back or flank area
Gross hematuria
Abdominal pain, usually worsened on exertion and eased by lying down
Assessment-Physical Findings
Microscopic or gross hematuria
Increased abdominal girth
Signs of an enlarging kidney mass
Grossly enlarged kidneys (in advanced stages)
Uremic fetor
Diagnostic Test Results-Laboratory
Urinalysis may show hematuria, bacteriuria, or proteinuria.
Creatinine clearance test results may show renal insufficiency or failure.
Hematocrit may be elevated.
Serum albumin levels may be decreased.
Serum electrolyte levels may reveal hyponatremia, hyperkalemia, hyperphosphatemia, or hypocalcemia.
Diagnostic Test Results-Imaging
Excretory or retrograde urography reveals enlarged kidneys, with pelvic elongation, flattening of the calyces, and indentations caused by cysts.
Magnetic resonance imaging (preferred test) shows multiple areas of cystic damage.
Monitoring of renal function
Dialysis; renal replacement therapy
Transcutaneous electrical nerve stimulation (TENS) and hypnotherapy for chronic pain
Fluid management based on degree of renal dysfunction
As tolerated in early stages
Avoidance of contact sports with advanced disease
Exercise to manage hypertension
Analgesics, such as opioids, transcutaneous opioid patches, or perinephric injection of local anesthetics, for pain relief
Antibiotics, such as ciprofloxacin hydrochloride, levofloxacin, or trimethoprim-sulfamethoxazole for urinary tract infection
Antihypertensive agents, such as angiotensin-converting enzyme (ACE) inhibitors (captopril, enalapril, or lisinopril) or angiotensin receptor blockers (losartan potassium, irbesartan, or candesartan cilexetil), for hypertension
Diuretics, such as furosemide, to treat hypertension and renal calculi
Electrolyte replacements, such as calcium carbonate, and phosphate binders to reduce phosphorus load in renal failure.
Kidney transplantation
Surgical drainage for cystic abscess or retroperitoneal bleeding
Nursing Considerations-Nursing Diagnoses
Acute pain
Chronic pain
Deficient fluid volume
Impaired urinary elimination
Ineffective coping
Risk for ineffective renal perfusion
Risk for infection
Risk for injury
Nursing Considerations-Expected Outcomes
report feelings of increased comfort
identify measures to address chronic pain
maintain fluid balance
verbalize the importance of balancing activity with adequate rest periods
demonstrate skill in managing the urinary elimination problem
demonstrate adaptive coping behaviors
exhibit adequate renal function
remain free from signs and symptoms of infection
avoid or minimize complications.
Nursing Considerations-Nursing Interventions
Give prescribed drugs, including ACE inhibitors to control hypertension; if giving diuretics, obtain specimens for serum electrolyte levels, especially potassium, which may be decreased.
Provide comfort measures, including opioid analgesics; assist the patient with relaxation techniques and the use of TENS.
Provide fluids and foods based on the patient's condition, encourage increased fluids if the patient has a urinary tract infection, and restrict fluids if the patient has renal failure.
Provide supportive care to minimize symptoms.
Obtain specimens for urinalysis and culture and sensitivity as ordered to evaluate for hematuria, proteinuria, and infection; obtain specimens for laboratory tests, such as electrolyte levels, as ordered.
Individualize patient care, as appropriate
Allow the patient to verbalize his feelings and concerns, especially related to possible progression of the disease and renal failure; provide support and guidance.
Prepare the patient for dialysis or renal replacement therapy as indicated.
Encourage the parents of a child with the infantile form to obtain genetic counseling.
Prepare the patient and his family for possible renal transplant or surgery.
