Urolithiasis Nursing Care Plan & Management

Description

Urolithiasis refers to stones (calculi) in the urinary tract.
Stones are formed in the urinary tract when the urinary concentration of substances such as calcium oxalate, calcium phosphate, and uric acid increases.
Stones vary in size from minute granular deposits to the size of an orange.
Factors that favor formation of stones include infection, urinary stasis, and periods of immobility, all of which slow renal drainage and alter calcium metabolism.
The problem occurs predominantly in the third to ﬁfth decades and affects men more often than women.

Clinical Manifestations

Manifestations depend on the presence of obstruction, infection, and edema. Symptoms range from mild to excruciating pain and discomfort.

Stones in Renal Pelvis

Intense, deep ache in costovertebral region
Hematuria and pyuria
Pain that radiates anteriorly and downward toward bladder in female and toward testes in male
Acute pain, nausea, vomiting, costovertebral area tenderness (renal colic)
Abdominal discomfort, diarrhea

Ureteral Colic (Stones Lodged in Ureter)

Acute, excruciating, colicky, wavelike pain, radiating down the thigh to the genitalia
Frequent desire to void, but little urine passed; usually contains blood because of the abrasive action of the stone (known as ureteral colic)

Stones Lodged in Bladder

Symptoms of irritation associated with urinary tract infection and hematuria
Urinary retention, if stone obstructs bladder neck
Possible urosepsis if infection is present with stone

Assessment and Diagnostic Methods

Diagnosis is conﬁrmed by xrays of the kidneys, ureters, and bladder (KUB) or by ultrasonography, IV urography, or retrograde pyelography.
Blood chemistries and a 24hour urine test for measurement of calcium, uric acid, creatinine, sodium, pH, and total volume.
Chemical analysis is performed to determine stone composition.

Medical Management

Basic goals are to eradicate the stone, determine the stone type, prevent nephron destruction, control infection, and relieve any obstruction that may be present.

Pharmacologic and Nutritional Therapy

Opioid analgesic agents (to prevent shock and syncope) and nonsteroidal antiinﬂammatory drugs (NSAIDs).
Increased ﬂuid intake to assist in stone passage, unless patient is vomiting; patients with renal stones should drink eight to ten 8oz glasses of water daily or have IV ﬂuids prescribed to keep the urine dilute.
For calcium stones: reduced dietary protein and sodium intake; liberal ﬂuid intake; medications to acidify urine, such as ammonium chloride and thiazide diuretics if parathormone production is increased.
For uric stones: lowpurine and limited protein diet; allopurinol (Zyloprim).
For cystine stones: lowprotein diet; alkalinization of urine; increased ﬂuids.
For oxalate stones: dilute urine; limited oxalate intake (spinach, strawberries, rhubarb, chocolate, tea, peanuts, and wheat bran).

Stone Removal Procedures

Ureteroscopy: stones fragmented with use of laser, electrohydraulic lithotripsy, or ultrasound and then removed.
Extracorporeal shock wave lithotripsy (ESWL).
Percutaneous nephrostomy; endourologic methods.
Electrohydraulic lithotripsy.
Chemolysis (stone dissolution): alternative for those who are poor risks for other therapies, refuse other methods, or have easily dissolved stones (struvite).
Surgical removal is performed in only 1% to 2% of patients.

Nursing Process

Assessment

Assess for pain and discomfort, including severity, location, and radiation of pain.
Assess for associated symptoms, including nausea, vomiting, diarrhea, and abdominal distention.
Observe for signs of urinary tract infection (chills, fever, frequency, and hesitancy) and obstruction (frequent urination of small amounts, oliguria, or anuria).
Observe urine for blood; strain for stones or gravel.
Focus history on factors that predispose patient to urinary tract stones or that may have precipitated current episode of renal or ureteral colic.
Assess patient’s knowledge about renal stones and measures to prevent recurrence.

Diagnosis

Nursing Diagnoses

Acute pain related to inﬂammation, obstruction, and abrasion of the urinary tract
Deﬁcient knowledge regarding prevention of recurrence of renal stones

Collaborative Problems/Potential Complications

Infection and urosepsis (from urinary tract infection and pyelonephritis)
Obstruction of the urinary tract by a stone or edema, with subsequent acute renal failure

Planning and Goals

Major goals may include relief of pain and discomfort, prevention of recurrence of renal stones, and absence of complications.

Nursing Interventions

Relieving Pain

Administer opioid analgesics (IV or intramuscular) with IV NSAID as prescribed.
Encourage and assist patient to assume a position of comfort.
Assist patient to ambulate to obtain some pain relief.
Monitor pain closely and report promptly increases in severity.

Monitoring and Managing Complications

Encourage increased ﬂuid intake and ambulation.
Begin IV ﬂuids if patient cannot take adequate oral ﬂuids.
Monitor total urine output and patterns of voiding.
Encourage ambulation as a means of moving the stone through the urinary tract.
Strain urine through gauze.
Crush any blood clots passed in urine, and inspect sides of urinal and bedpan for clinging stones.
Instruct patient to report decreased urine volume, bloody or cloudy urine, fever, and pain.
Instruct patient to report any increase in pain.
Monitor vital signs for early indications of infection; infections should be treated with the appropriate antibiotic agent before efforts are made to dissolve the stone.

Teaching Points

Explain causes of kidney stones and ways to prevent recurrence.
Encourage patient to follow a regimen to avoid further stone formation, including maintaining a high ﬂuid intake.
Encourage patient to drink enough to excrete 3,000 to 4,000 mL of urine every 24 hours.
Recommend that patient have urine cultures every 1 to 2 months the ﬁrst year and periodically thereafter.
Recommend that recurrent urinary infection be treated vigorously.
Encourage increased mobility whenever possible; discourage excessive ingestion of vitamins (especially vitamin D) and minerals.
If patient had surgery, instruct about the signs and symptoms of complications that need to be reported to the physician; emphasize the importance of followup to assess kidney function and to ensure the eradication or removal of all kidney stones to the patient and family.
If patient had ESWL, encourage patient to increase ﬂuid intake to assist in the passage of stone fragments; inform the patient to expect hematuria and possibly a bruise on the treated side of the back; instruct patient to check his or her temperature daily and notify the physician if the temperature is greater than 38.C (about 101.F), or the pain is unrelieved by the prescribed medication.
Provide instructions for any necessary home care and followup.

PROVIDING HOME AND FOLLOWUP CARE AFTER ESWL

Instruct patient to increase ﬂuid intake to assist passage of stone fragments (may take 6 weeks to several months after procedure).
Instruct patient about signs and symptoms of complications: fever, decreasing urinary output, and pain.
Inform patient that hematuria is anticipated but should subside in 24 hours.
Give appropriate dietary instructions based on composition of stones.
Encourage regimen to avoid further stone formation; advise patient to adhere to prescribed diet.
Teach patient to take sufficient fluids in the evening to prevent urine from becoming too concentrated at night.

CONTINUING CARE

Closely monitor the patient to ensure that treatment has been effective and that no complications have developed.
Assess the patient’s understanding of ESWL and possible complications; assess the patient’s understanding of factors that increase the risk of recurrence of renal calculi and strategies to reduce those risks.
Assess the patient’s ability to monitor urinary pH and interpret the results during followup visits.
Ensure that the patient understands the signs and symptoms of stone formation, obstruction, and infection and the importance of reporting these signs promptly.
If medications are prescribed for the prevention of stone formation, explain their actions, importance, and side effects to the patient.

Provide information about disease process/prognosis and treatment needs.

Nursing Diagnosis: Pain, acute

May be related to

Increased frequency/force of ureteral contractions
Tissue trauma, edema formation; cellular ischemia

Possibly evidenced by

Reports of colicky pain
Guarding/distraction behaviors, restlessness, moaning, self-focusing, facial mask of pain, muscle tension
Autonomic responses

Desired outcomes/evaluation criteria—patient will:

Report pain is relieved with spasms controlled.
Appear relaxed, able to sleep/rest appropriately.

Nursing Interventions

Pain Management

Independent

Document location, duration, intensity (0–10 scale), and radiation. Note nonverbal signs, e.g., elevated BP and pulse, restlessness, moaning, thrashing about.
- Rationale: Helps evaluate site of obstruction and progress of calculi movement. Flank pain suggests that stones are in the kidney area, upper ureter. Flank pain radiates to back, abdomen, groin, genitalia because of proximity of nerve plexus and blood vessels supplying other areas. Sudden, severe pain may precipitate apprehension, restlessness, severe anxiety.
Explain cause of pain and importance of notifying caregivers of changes in pain occurrence/characteristics.
- Rationale: Provides opportunity for timely administration of analgesia (helpful in enhancing patient’s coping ability and may reduce anxiety) and alerts caregivers to possibility of passing of stone/developing complications. Sudden cessation of pain usually indicates stone passage.
Provide comfort measures, e.g., back rub, restful environment.
- Rationale: Promotes relaxation, reduces muscle tension, and enhances coping.
Assist with/encourage use of focused breathing, guided imagery, diversional activities.
- Rationale: Redirects attention and aids in muscle relaxation.
Encourage/assist with frequent ambulation as indicated and increased fluid intake of at least 3–4 L/day within cardiac tolerance.
- Rationale: Renal colic can be worse in the supine position. Vigorous hydration promotes passing of stone, prevents urinary stasis, and aids in prevention of further stone formation.
Note reports of increased/persistent abdominal pain.
- Rationale: Complete obstruction of ureter can cause perforation and extravasation of urine into perirenal space. This represents an acute surgical emergency.
Administer medications as indicated: Narcotics, e.g., meperidine (Demerol), morphine;
- Rationale: Usually given during acute episode to decrease ureteral colic and promote muscle/mental relaxation.
Antispasmodics, e.g., flavoxate (Urispas) oxybutynin (Ditropan)
- Rationale: Decreasing reflex spasm may decrease colic and pain.

Collaborative

Apply warm compresses to back.
- Rationale: Relieves muscle tension and may reduce reflex spasms.
Maintain patency of catheters when used.
- Rationale: Prevents urinary stasis/retention, reduces risk of increased renal pressure and infection.

Nursing Diagnosis: Urinary Elimination, impaired

May be related to

Stimulation of the bladder by calculi, renal or ureteral irritation
Mechanical obstruction, inflammation

Possibly evidenced by

Urgency and frequency; oliguria (retention)
Hematuria

Desired outcomes/evaluation criteria—patient will:

Urinary Elimination

Void in normal amounts and usual pattern.
Experience no signs of obstruction.

Nursing Interventions

Urinary Elimination Enhancement

Independent

Monitor I&O and characteristics of urine.
- Rationale: Provides information about kidney function and presence of complications, e.g., infection and hemorrhage. Bleeding may indicate increased obstruction or irritation of ureter. Note: Hemorrhage due to ureteral ulceration is rare.
Determine patient’s normal voiding pattern and note variations.
- Rationale: Calculi may cause nerve excitability, which causes sensations of urgent need to void. Usually frequency and urgency increase as calculus nears ureterovesical junction.
Encourage increased fluid intake.
- Rationale: Increased hydration flushes bacteria, blood, and debris and may facilitate stone passage.
Strain all urine. Document any stones expelled and send to laboratory for analysis
- Rationale: Retrieval of calculi allows identification of type of stone and influences choice of therapy.
Investigate reports of bladder fullness; palpate for suprapubic distension. Note decreased urine output, presence of periorbital/dependent edema.
- Rationale: Urinary retention may develop, causing tissue distension (bladder/kidney), and potentiates risk of infection, renal failure.
Observe for changes in mental status, behavior, or level of consciousness.
- Rationale: Accumulation of uremic wastes and electrolyte imbalances can be toxic to the CNS.

Collaborative

Monitor laboratory studies, e.g., electrolytes, BUN, Cr.
- Rationale: Elevated BUN, Cr, and certain electrolytes indicate presence/degree of kidney dysfunction.
Obtain urine for culture and sensitivities.
- Rationale: Determines presence of UTI, which may be causing/complicating symptoms.
Administer medications as indicated, e.g.: Acetazolamide (Diamox), allopurinol (Zyloprim)
- Rationale: Increases urine pH (alkalinity) to reduce formation of acid stones. Antigout agents such as allopurinol (Zyloprim) also lower uric acid production and potential of stone formation.
Hydrochlorothiazide (Esidrix, HydroDIURIL), chlorthalidone (Hygroton)
- Rationale: May be used to prevent urinary stasis and decrease calcium stone formation if not caused by underlying disease process such as primary hyperthyroidism or vitamin D abnormalities.
Ammonium chloride; potassium or sodium phosphate
- Rationale: Reduces phosphate stone formation.
Antibiotics
- Rationale: Presence of UTI/alkaline urine potentiates stone formation.
Sodium bicarbonate
- Rationale: Replaces losses incurred during bicarbonate wasting and/or alkalinization of urine; may reduce/prevent formation of some calculi.
Ascorbic acid.
- Rationale: Acidifies urine to prevent recurrence of alkaline stone formation.

Nursing Diagnosis: Fluid Volume, risk for deficient

Risk factors may include

Nausea/vomiting (generalized abdominal and pelvic nerve irritation from renal or ureteral colic)
Postobstructive diuresis

Possibly evidenced by

[Not applicable; presence of signs or symptoms establishes an actual]

Desired outcomes/evaluation criteria—patient will:

Hydration

Maintain adequate fluid balance as evidenced by vital signs and weight within patient’s normal range, palpable peripheral pulses, moist mucous membranes, good skin turgor.

Nursing Interventions

Fluid/Electrolyte Management

Independent

Monitor I&O.
- Rationale: Comparing actual and anticipated output may aid in evaluating presence/degree of renal stasis/impairment.Note: Impaired kidney functioning and decreased urinary output can result in higher circulating volumes with signs/symptoms of HF.
Document incidence and note characteristics and frequency of vomiting and diarrhea, as well as accompanying or precipitating events.
- Rationale: Nausea/vomiting and diarrhea are commonly associated with renal colic because celiac ganglion serves both kidneys and stomach. Documentation may help rule out other abdominal occurrences as a cause for pain or pinpoint calculi.
Increase fluid intake to 3–4 L/day within cardiac tolerance.
- Rationale: Maintains fluid balance for homeostasis and “washing” action that may flush the stone(s) out. Dehydration and electrolyte imbalance may occur secondary to excessive fluid loss (vomiting and diarrhea).
Monitor vital signs. Evaluate pulses, capillary refill, skin turgor, and mucous membranes.
- Rationale: Indicators of hydration/circulating volume and need for intervention. Note: Decreased GFR stimulates production of renin, which acts to raise BP in an effort to increase renal blood flow.
Weigh daily.
- Rationale: Rapid weight gain may be related to water retention.

Collaborative

Monitor Hb/Hct, electrolytes.
- Rationale: Assesses hydration and effectiveness of/need for interventions.
Administer IV fluids.
- Rationale: Maintains circulating volume (if oral intake is insufficient), promoting renal function.
Provide appropriate diet, clear liquids, bland foods as tolerated.
- Rationale: Easily digested foods decrease GI activity/irritation and help maintain fluid and nutritional balance.
Administer medications as indicated: antiemetics, e.g., prochlorperazine (Compazine).
- Rationale: Reduces nausea/vomiting.

Nursing Diagnosis: Knowledge, deficient [Learning Need] regarding condition, prognosis, treatment, self-care, and discharge needs.

May be related to

Lack of exposure/recall; information misinterpretation
Unfamiliarity with information resources

Possibly evidenced by

Questions; request for information; statement of misconception
Inaccurate follow-through of instructions, development of preventable complications

Desired outcomes/evaluation criteria—patient will:

Knowledge: Illness Care

Verbalize understanding of disease process and potential complications.
Correlate symptoms with causative factors.
Verbalize understanding of therapeutic needs.
Initiate necessary lifestyle changes and participate in treatment regimen.

Nursing Interventions

Teaching: Disease Process

Independent

Review disease process and future expectations.
- Rationale: Provides knowledge base from which patient can make informed choices.
Stress importance of increased fluid intake, e.g., 3–4L/day or as much as 6–8 L/day. Encourage patient to notice dry mouth and excessive diuresis/diaphoresis and to increase fluid intake whether or not feeling thirsty.
- Rationale: Flushes renal system, decreasing opportunity for urinary stasis and stone formation. Increased fluid losses/dehydration require additional intake beyond usual daily needs.
Review dietary regimen, as individually appropriate:
- Rationale: Diet depends on the type of stone. Understanding reason for restrictions provides opportunity for patient to make informed choices, increases cooperation with regimen, and may prevent recurrence.
Low-purine diet, e.g., limited lean meat, turkey, legumes, whole grains, alcohol
- Rationale: Decreases oral intake of uric acid precursors.
Low-calcium diet, e.g., limited milk, cheese, green leafy vegetables, yogurt
- Rationale: Reduces risk of calcium stone formation. Note:Research suggests that restricting dietary calcium is not helpful in reducing calcium-stone formation, and researchers, although not advocating high-calcium diets, are urging that calcium limitation be reexamined.
Low-oxalate diet, e.g., restrict chocolate, caffeine-containing beverages, beets, spinach.
- Rationale: Reduces calcium oxalate stone formation.
Short regimen: low-calcium/phosphorus diet with aluminum carbonate gel 30–40 mL, 30 min pc/hs.
- Rationale: Prevents phosphatic calculi by forming an insoluble precipitate in the GI tract, reducing the load to the kidney nephron. Also effective against other forms of calcium calculi. Note: May cause constipation.
Discuss medication regimen; avoidance of OTC drugs, and reading all product/food ingredient labels.
- Rationale: Drugs will be given to acidify or alkalize urine, depending on underlying cause of stone formation. Ingestion of products containing individually contraindicated ingredients (e.g., calcium, phosphorus) potentiates recurrence of stones.
Encourage regular activity/exercise program.
- Rationale: Inactivity contributes to stone formation through calcium shifts and urinary stasis.
Active-listen concerns about therapeutic regimen/lifestyle changes.
- Rationale: Helps patient work through feelings and gain a sense of control over what is happening.
Identify signs/symptoms requiring medical evaluation, e.g., recurrent pain, hematuria, oliguria.
- Rationale: With increased probability of recurrence of stones, prompt interventions may prevent serious complications.
Demonstrate proper care of incisions/catheters if present.
- Rationale: Promotes competent self-care and independence.
