  9. Imaging: General
    1. See Nephrolithiasis Imaging
  10. Imaging: Sample approach for suspected uncomplicated Nephrolithiasis (emergency department)
    1. Background
      1. Intention
        1. Reduce ionizing radiation exposure in the evaluation of Nephrolithiasis
        2. Avoid delaying intervention (when indicated)
      2. Bedside renal Ultrasound can reliably identify stones >5mm based on Hydronephrosis
        1. Goertz (2010) Am J Emerg Med 28(7):813-6 [PubMed]
        2. Edmonds (2010) CJEM 12(3): 201-6 [PubMed]
      3. Bedside Ultrasound is a safe evaluation strategy without serious missed conditions
        1. Relies on appropriate patient selection (Ureteral Colic most likely, no significant comorbidity)
        2. Moore (2019) Ann Emerg Med 74(3): 391-9 [PubMed]
        3. Smith-Bindman (2014) N Engl J Med 371(12):1100-10 +PMID:25229916 [PubMed]
    2. Step 1: Suspicion for uncomplicated Nephrolithiasis
      1. Hematuria and abdominal, pelvic or Flank Pain AND
      2. No Urinary Tract Infection AND
      3. No serious comorbidity (e.g. cancer, AAA risk) or other confounding factor (e.g. single Kidney)
    3. Step 2: Bedside renal Ultrasound (bilateral for comparison) and Bladder (for obstruction, distal stone shadowing at UVJ)
      1. Hydronephrosis on side of pain
        1. Consider empiric treatment of Ureterolithiasis with expectant management
        2. Consider other causes of Hydronephrosis (e.g. Abdominal Aortic Aneurysm)
        3. Consider non-contrast CT as indicated (see Step 3 below)
      2. No Hydronephrosis
        1. Consider imaging with discussion of risks (e.g. CT-associated Radiation Exposure)
          1. Strongly consider CT if UTI by Urinalysis (exclude infected stone)
          2. False NegativeUltrasound for Hydronephrosis
          3. Alternative intraabdominal diagnosis (e.g. Appendicitis, Diverticulitis)
        2. May treat empirically as small, non-obstructing stone (likely to pass without intervention)
        3. Close interval follow-up
        4. Consider alternative diagnoses
    4. Step 3: Consider Helical, Non-Contrast CT Abdomen and Pelvis for Ureterolithiasis
      1. Non-Contrast CT indications
        1. First stone suspected (no prior imaging or Ureterolithiasis history), esp. if over age 50 years old
        2. Persistent Ureterolithiasis symptoms at 14 weeks without prior imaging
        3. Infected stone suspected
        4. Urology consulted for intervention (see indications as below)
        5. Alternative intraabdominal diagnosis (e.g. Appendicitis, Diverticulitis)
      2. Consider KUB Abdominal XRay if CT positive for Ureteral Stone of 5 mm or greater
        1. Helical CT will localize the stone and ease simultaneous identification on KUB XRay
        2. KUB XRay allows for serial XRays for monitoring progression without significant radiation exposure
        3. KUB XRay is preferred over CT scout film due to better resolution and for easier comparison on future films
  11. Labs: Initial diagnostics
    1. Precaution: Absent gross and Microscopic Hematuria does not exclude Nephrolithiasis (may miss up to 10% of cases)
    2. Urinalysis with reflex to Urine Culture
      1. Microscopic or Gross Hematuria in 90% of Nephrolithiasis cases
      2. Evaluate for Urinary Tract Infection
        1. Nephrolithiasis with Urinary Tract Infection is high risk and requires immediate urologic Consultation
        2. Factors most suggestive or higher risk of Urinary Tract Infection complicating Nephrolithiasis
          1. Fever (associated Likelihood Ratio of 10)
          2. Female (associated Likelihood Ratio of 27)
          3. Positive Urine Nitrite (associated Likelihood Ratio of 36)
          4. White Blood Cells in urine has Test Specificity of 25%
          5. Abrahamian (2013) Ann Emerg Med 62(5): 526-33 [PubMed]
  12. Labs: Evaluation of single stone former without risk (labs to consider)
    1. Chemistry panel
      1. Serum Electrolytes
      2. Serum Calcium
    2. Renal Function tests
      1. Blood Urea Nitrogen
      2. Serum Creatinine
    3. Serum Uric Acid
    4. Stone Analysis (nidus and outer layer)
      1. Stone analysis is important to direct preventive strategies, esp. if Ureterolithiasis Risk Factors
        1. However, stone analysis is often not performed for the initial stone
      2. Microscopic Crystal Analysis
        1. Envelope shape crystal: Calcium oxalate
        2. Diamond shape crystal: Uric Acid
        3. Coffin-lid shape crystal: Struvite
        4. Hexagon shape crystal: Cystine
  13. Labs: Evaluation of recurrent stone formation
    1. See those labs listed above
    2. Parathyroid Hormone level
      1. Obtain if Urine Calcium >10 mg/dl
    3. 24 hour Urine Collection
      1. Urine pH
        1. Acidic urine predisposes to Uric Acid stones, Cystine Stones and Calcium Oxalate Stones
        2. Alkaline urine predisposes to Struvite Stones and Calcium Phosphate Stones
      2. Urine Sodium
      3. Urine Creatinine
      4. Urine Calcium (Hypercalciuria >300 mg/day)
      5. Urine Uric Acid (Hyperuricosuria >750 mg/day)
      6. Urine Oxalate (Hyperoxaluria >40 mg/day)
      7. Urine Citrate (Hypocitraturia <320 mg/day)
      8. Urine Magnesium (Hypomagnesuria <50 mg/day)
      9. Other urine labs to consider
        1. Urine Phosphorus
        2. Urine Calcium Oxalate (Supersaturation)
        3. Urine Calcium Phosphate
  14. Precautions
    1. Do not miss concurrent Urinary Tract Infection and Ureterolithiasis
    2. Do not miss Abdominal Aortic Aneurysm (which may also cause Hydronephrosis or otherwise mimic Renal Colic)
    3. Post-renal transplant obstructive uropathy
      1. Struvite Stones are more common with corynebacterium urealyticum infections (seen in transplant patients)
      2. Consult urology
      3. Corynebacterium antibiotic coverage
        1. Vancomycin

      1. IV fluid hydration as of 2012 is limited to those patients with signs, symptoms of Dehydration
        1. May worsen pain, and does not offer significant benefit in a well-hydrated patient
        2. May allow for Emergency Department Nephrolithiasis management without Intravenous Access
        3. Patient could be discharged after Urinary Tract Infection was excluded and analgesia administered
      2. No evidence that high volume IV fluids improves stone passage, pain control or avoids intervention

            1. Pathan (2016) Lancet 387(10032): 1999-2007 [PubMed]
      3. Opioids may be required as adjuncts to NSAIDs and Acetaminophen for adequate analgesia
        1. If Morphine or Oxycodone are used, then Acetaminophen may be used separately
    4. Medical Expulsive Therapy
      1. Efficacy - mixed data (may be allow moderate stones >=5 mm to pass without intervention)
        1. Some studies have shown benefit in stone expulsion with alpha antagonists

      2. See Medication Causes of Nephrolithiasis
    3. Prevention can be more finely directed by stone type
      1. See Calcium Oxalate Nephrolithiasis for prevention of the most common type
    4. Maintain fluid intake >2.5 to 3 Liters per day
      1. Most important single measure
      2. Ingest 8 to 12 ounces fluid on awakening and at bedtime
      3. Avoid soft drinks (esp. colas which contain phosphoric acid, predisposing to stone formation)
      4. Recommended fluids
        1. Water
        2. Citrus juice
    5. Maintain Urine Volume > 2 Liters per day
      1. Periodically measure Urine Output in a 2 liter bottle
      2. Urine should be clear in appearance with minimal color
    6. Dietary restrictions
      1. Limit animal protein to 8 ounces per day (or <1 gram/kg/day)
        1. Animal protein increases urinary Calcium and Uric Acid excretion
        2. Animal protein decreases urinary pH and urinary citrate excretion
      2. Limit Sodium intake to <4 grams per day (target 2.3 grams)
        1. Increases renal Calcium absorption and lower urinary Calcium excretion
      3. Limit Oxalate Containing Foods (e.g. tea, tomatoes, cashews, almonds, potatoes, spinach)
        1. Decreases urinary oxalate excretion
      4. Limit high sugar or fat content (Obesity predisposes to stone formation)
      5. Avoid excessive Vitamin C (target <1 g/day)
    7. Lifestyle
      1. Move toward target BMI, Ideal Weight
      2. Encourage daily physical Exercise
    8. Dietary increases or no restriction
      1. Increase vegetable Dietary Fiber
      2. Maintain Calcium intake at at least 1000 to 1200 mg/day (if Calcium Oxalate Stone)

Kidney Calculi (C0022650)

Definition (MEDLINEPLUS)

A kidney stone is a solid piece of material that forms in the kidney from substances in the urine. It may be as small as a grain of sand or as large as a pearl. Most kidney stones pass out of the body without help from a doctor. But sometimes a stone will not go away. It may get stuck in the urinary tract, block the flow of urine and cause great pain.

The following may be signs of kidney stones that need a doctor's help:

  • Extreme pain in your back or side that will not go away
  • Blood in your urine
  • Fever and chills
  • Vomiting
  • Urine that smells bad or looks cloudy
  • A burning feeling when you urinate

Your doctor will diagnose a kidney stone with urine, blood, and imaging tests.

If you have a stone that won't pass on its own, you may need treatment. It can be done with shock waves; with a scope inserted through the tube that carries urine out of the body, called the urethra; or with surgery.
