Definition Kidney Stones are small, hard deposits of mineral and acid salts on the inner surfaces of the kidneys Alternative names include: Renal Lithiasis Renal Calculi Nephrolithiasis (Kidney Stone Disease) Stones are classified by their location in the urinary system and their composition of crystals.

Statistics Incidence Rate: 80% of stones under 2mm in size More than 1 million cases annually in US 1 in 272 or 3.6 per 1000 Americans develop stones annually. 80% of stones under 2mm in size 90% of stones pass through the urinary system spontaneously Generally stone smaller than 6mm are passable  (National Institute of Diabetes and Digestive and Kidney Diseases; NIDDK) (National Kidney and Urologic Disease Information Clearinghouse; NKUDIC)

Kidney Stone Formation Causes: Highly concentrated urine, urine stasis Imbalance of pH in urine Acidic: Uric and Crystine Stones Alkaline: Calcium Stones Gout Hyperparathyroidism Inflammatory Bowel Disease UTI Medications Lasix, Topamax, Crixivan Explain crystalization http://www.pilotfriend.com/aeromed/medical/images2/25.jpg

Types of Stones Calcium Oxalate Calcium Phosphate Struvite Uric Acid Most common Calcium Phosphate Struvite More common in woman than men. Commonly a result of UTI. Uric Acid Caused by high protein diet and gout. Cystine Fairly uncommon; generally linked to a hereditary disorder. When oxalate combines with calcium, which prevents the oxalate from being absorbed in the intestinal tract. It then goes through the kidneys where is can pose a problem. Stones classified by majority of crystal that they are composed of. Foods high is oxalate, rhubarb, star fruit, beets, beet greens, collards, okra, refried beans, spinach, Swiss chard, sweet potatoes, sesame seeds, almonds and soy products, vitamin D, metabolic disorders, and bypass surgery increase calcium oxalate concentration in urine.

Case Study It is a hot summer day, and you are an RN in the emergency department (ED).  S.R., an 18-year-old woman, comes to the ED with severe flank and abdominal pain and N/V. S.R. looks very tired, her skin is warm to touch, and she is perspiring. She paces about the room doubled-over and is clutching her abdomen.  S.R.  tells you that the pain started early this morning and has been pretty steady for the past  hours. She gives a history of working outside as a landscaper and takes little time for water breaks. Her past medical history (PMH) includes 3 kidney stone attacks, all during late summer. Exam findings are that her abdomen is soft and w/o tenderness, but her left flank is extremely tender to touch, palpation, and percussion. You place S.R. in one of the examination rooms and take the following VS 118/98, 90, 20, 99 F. UA shows RBC of 50 to 100 on voided specimen, WBC 0.

What key factors are important to consider?

Signs and Symptoms Additional S/S: What are the key findings? Presence of UTI Fever or Chills Pain in groin, labia or testicles Cloudy or foul-smelling urine Dysuria Persistent urge to void What are the key findings? Severe flank pain Abdominal pain Nausea and vomiting Fatigue Elevated temperature, BP, and respirations UA positive for RBC Objective Data: perspiration, clutching of the abdomen, doubled-over. Steady Pain Left flank tendernes pain typically starts at side or back, just below your ribs, and radiates to ones lower abdomen and groin. Often begins when stone reaches ureters http://knol.google.com/k/-/-/27ifsyywko3wx/sqc1f9/kidneystonesymptoms.jpg

What additional information should you ask this patient?

Additional Information Family history Current medications Frequency of urination Do you experience pain while urinating? What is your typical diet? How did patient’s kidney stones resolve themselves in the past? http://erstories.net/wp-content/uploads/2008/10/kidneystone1a.jpg

Identify this patient’s risk factors.

Risk Factors What are her risk factors? Additional risk factors: Past Medical History Hx of 3 kidney stone attacks Dehydration/Lack of Fluids Occupational exposure Labor Intensive Outdoors Weather/Climate Hot, dry Additional risk factors: Family or Personal Hx Gender (male) Age (20-55) Race (Caucasian) Diet High sodium High protein Food high in oxalate  Vit A/D, grapefruit juice         Sedentary Lifestyle Obesity High Blood Pressure http://savethelobsters.files.wordpress.com/2009/02/ist2_4588664_half_empty_glass_of_water_with_clipping_path.jpg

Abnormal Lab Values BUN Creatinine Urine Analysis https://www.clevelandclinic.org/heartcenter/images/guide/tests/lab.gif http://www.ganfyd.org/images/f/fb/Dipstick_bottle.jpg

Diagnostic Studies Test and Diagnostics: Blood Analysis Urine Analysis CT Scan Abdominal x-ray Ultrasound Retrograde Pyelogram Cystoscopy Intravenous pyelography Blood analyis-look at calcium levels Intravenous pyelography: A contrast dye is injected into a vein in your arm and a series of X-rays is taken as the dye moves through your kidneys, ureters and bladder. Helps determine stone location and extent of blockage. Not for pt with renal failure. http://knol.google.com/k/-/-/PYwIQr_i/GXb8Fg/Stone%20CT.jpg

What questions do you need to ask before a patient has an IV pyelogram? IVP = Used to localize the degree and site of obstruction or to confirm the presence of a radiolucent  stone)

Answer: Check BUN and Creatinine levels prior to IVP Do you have a history of renal failure? Contraindicated with renal failure Have you ever have a reaction to iodine? Contrast contains iodine Is there a possibility you could be pregnant? Are you currently taking any medications? Metformin may react with contrast Check BUN and Creatinine levels prior to IVP Need to check the patient’s renal function because this test is contraindicated in patients with renal failure. Contrast has iodine in it. Contraindicated if on metformin.

What are Nursing Interventions? Nursing Diagnosis: Acute pain r/t obstruction from renal calculi as manifested by patient being doubled-over, pacing around the room, and patient verbalizing pain upon assessment. Goal: patient will state pain is at a manageable level within 2 hours of admission. What are Nursing Interventions?

Nursing Goal/Interventions: Administer pain medication as ordered by physician. Provide non-pharmaceutical techniques such as imagery and/or meditation to relieve pain. Patient will determine manageable pain level. Patient will be asked about any concerns and/or fears that may be associated with pain. Provide emotional support for the patient. Reassess patient’s pain levels within 1 hour after administration of pain medications.

What are Nursing Interventions? Nursing Diagnoses: Deficient knowledge r/t fluid requirements and dietary restrictions as manifested by reoccurring stones. Goal: Patient will state methods to prevent future stones by the time patient is D/C. A plan of care will also be created with the patient before patient is D/C to prevent reoccurrence of kidney stones. Risk for infection r/t kidney stone obstruction of urinary tract causing stasis of urine. Goal: Patient’s urine will be yellow and clear upon D/C and patient will not have a fever. UA with show no indication of UTI or other infection. What are Nursing Interventions?

Treatment Two Focuses of Treatment: Acute Treatment: Treatment of acute problems, such as pain, n/v, etc Identify cause and prevent kidney stones from reoccurring Acute Treatment: Pain Medication!!! Strain urine for stones Keep Hydrated Ambulation Diet Restrictions Emotional Support Invasive Procedure (may be necessary) do not need to over-hydrate since stone has already formed (2000-2200 ml/day) -encourage patient to keep mobile to promote movement of the stone from the upper to lower part of the ureter. Avoid foods high in ____: depends on the type of stone. http://www.free-press-release.com/members/members_pic/200906/img/1245774370.jpg

Surgical Procedures Lithotripsy: used to break into smaller fragments allowing it to pass through the urinary tract. Extracorporeal Shock-Wave (ESWL) Percutaneous Ultrasonic Electrohydraulic Laser Surgical Therapy Nephrolithotomy (Kidney) Pyelolithotomy (Renal Pelvis) Ureterolithotomy (Ureter) Basket Extraction Surgery may be needed to remove a kidney stone if it does not pass after a reasonable period of time and causes constant pain is too large to pass on its own or is caught in a difficult place blocks the flow of urine causes an ongoing urinary tract infection damages kidney tissue or causes constant bleeding has grown larger, as seen on follow-up x rays ESWL, shock waves that are created outside the body travel through the skin and body tissues until they hit the denser stones. The stones break down into small particles and are easily passed Nephrolithotomy: surgeon makes a tiny incision in the back and creates a tunnel directly into the kidney http://www.svhm.org.au/Department_Index/Lithotripsy/images/Kidney-Stones.gif

Prevention Patient Education Medication Hydration Diet Drink 3 liters of fluid per day (14 cups) Water Lemonade (citrate decrease stone formation) Diet Low sodium Watch amounts of oxalate Low protein Exercise/Increase Activity Medication http://3.bp.blogspot.com/_-gcaht5yp_0/SdINrCVuqdI/AAAAAAAAAGw/xeEk4-F3z_I/s320/foods+rich+in+oxalate+2.gif

Journal Article #1 Purpose: Determine effectiveness of an herbal supplement made out of varuna and banana stems, “Herbmed,” on kidney stones Study: 77 patients participated in a randomized, placebo, double-blinded study that was conducted in India from July 2007 to February 2008. Two groups were formed: Group A with calculi 5-10mm and Group B with calculi >10mm. Results: Patients relieving the herbal supplement showed a 33% reduction in the size of their kidney stone. Conclusion: Herbmed is an herbal treatment that may have promising effects in reducing kidney stone size and expulsion.

Journal Article #2 Purpose: To determine the possible effects fructose has on the formation of kidney stones. Study: The researchers looked at three different cohorts (older woman, younger women, and men) over combined 48 years of follow up. 4902 new symptomatic kidney stones were documented among these three cohorts. Results: The results from the study showed that there is a positive correlation between the intake of fructose and the development of kidney stones. Conclusion: Fructose intake can increase insulin resistance which lowers the pH in the urine and increases ones’ risk for the development of uric acid kidney stone. Nurses need to adequately assess the patient’s diet and educate patients on ways to prevent stones.

Journal Article #3 Purpose: The study looked specifically at anxiety associated with treatment, surgery, for kidney stones. Study: The anxiety of 66 patients was assessed before and after treatment, using three forms of measurement tools: palmar sweat test, visual analogue scale, and Speilberger state anxiety questionnaire. The two groups that were compared were open surgery to minimally/non-invasive treatment. Results: The results from the study showed no significant change in the questionnaire answers between the three indicators of anxiety. But, there was a fair reduction in the analogue scores post-operatively in-patients who had open surgery. These same patients also had a lower palmar sweat response. But, pre-operatively patients who going to have open surgery had higher analogue scores. Conclusion: The two primary causes of anxiety were pain and being under anesthesia. Open surgery treatment resulted in lower levels of anxiety than non-invasive treatments.
