Supportive therapy for [disease name] includes [therapy 1], [therapy 2], and [therapy 3].
The treatment of nephrolithiasis involves different measures e.g non pharmacological measures consisting of increased fluid intake, straining an dietary restrictions. Pharmacological measures include pain relief using NSAIDs and opioids., helping passage of stone spontaneously with drugs like [[tamsulosin]] and [[nifedipine]]. The treatment of underlying cause and being specific to type of stones is very important.It involves treating [[Hyperparathyroidism medical therapy|primary hyperparathyroidism]] and [[Renal tubular acidosis]]. For those having high urinary calcium, [[Hydrochlorothiazide]] or [[Chlorthalidone]] are used. For recurrent stones and high urine [[uric acid]], [[Allopurinol]] is used. For recurrent stones and [[hypocitraturia]], [[Potassium citrate]] is sued to alkalinize the urine. For uric acid stones, alkalinizing urine with [[potassium citrate]]/[[potassium bicarbonate]] is done and if needed [[Allopurinol]] is also used. For struvite stones, medical therapy is not of much help, although urease inhibitors such as  [[Acetohydroxamic Acid|acetohydroxamic acid]] can be given in urease +ve etiology. For cysteine stones, again alkalinizing urine helps along with [[Tiopronin]]. The Urological consult is needed when stone >10 mm in diameter, uncontrolled pain, [[Anuria]], or there is [[Acute kidney injury]].

Overview

The treatment of nephrolithiasis involves different measures e.g non pharmacological measures consisting of increased fluid intake, straining an dietary restrictions. Pharmacological measures include pain relief using NSAIDs and opioids., helping passage of stone spontaneously with drugs like tamsulosin and nifedipine. The treatment of underlying cause and being specific to type of stones is very important.It involves treating primary hyperparathyroidism and Renal tubular acidosis. For those having high urinary calcium, Hydrochlorothiazide or Chlorthalidone are used. For recurrent stones and high urine uric acid, Allopurinol is used. For recurrent stones and hypocitraturia, Potassium citrate is sued to alkalinize the urine. For uric acid stones, alkalinizing urine with potassium citrate/potassium bicarbonate is done and if needed Allopurinol is also used. For struvite stones, medical therapy is not of much help, although urease inhibitors such as acetohydroxamic acid can be given in urease +ve etiology. For cysteine stones, again alkalinizing urine helps along with Tiopronin. The Urological consult is needed when stone >10 mm in diameter, uncontrolled pain, Anuria, or there is Acute kidney injury.

Medical Therapy

Nephroliithiasis

Non pharmacological measures

  • Increased fluid intake
  • Straining
    • Stone ≤5 mm can pass spontaneously.
    • Passage of stone also depends on the site of stone[1]
  • Evaluating diet as per the composition of stones, for example:
    • Diet containing excess proteins can precipitate uric acid stones
    • Diet containing excess phosphorus can cause struvite stone

Pharmacological measures

  • Both NSAIDS and opiods are seen efficacious for the pain relief related to nephrolithiasis.[2]
  • The combination works in effective pain relief.[3]
  • NSAIDS should be stopped before undergoing Extracorporeal shockwave lithotripsy to reduce the risk of bleeding.
Pain relief
Non steroidal anti inflammatory drugs (NSAIDS)
  • Parenteral regimen
    • Preferred regimen (1): Ketorolac 60 mg as a single dose or 30 mg IM q6h
    • Alternative regimen (1): Ketorolac 10 to 30 mg (as single dose) IM and then q4-6 h as needed (maximum: 120 mg/day)
    • Alternative regimen (2): Ketorolac 30 mg as a single dose or 30 mg IV q6h (maximum: 120 mg/day)
  • Oral regimen
    • Preferred regimen (1): Ketorolac 20 mg, followed by 10 mg q4-6 h as needed; maximum: 40 mg/day; follows the parenteral dose (contraindicated in patients with renal failure)
    • Alternative regimen (1):Indomethacin 20 mg PO q8h
    • Alternative regimen (2):Indomethacin 40 mg PO q8-12h

Opioids

  • Parenteral regimen
    • Preferred regimen (1): Morphine 5 mg IV q4h as needed
Passage of stone
  • The passage of stones depend on the size and location of the stone.[4][5][6]
  • Stones ≤5 mm in diameter pass spontaneously.
  • It decrease as the size grows and not likely for sizes ≥10 mm in diameter.
  • Stones which are proximal are less likely to pass spontaneously.
  • Oral regimen
Type specific treatment

Treating the underlying cause is very important.
