Overview
Supportive therapy for [disease name] includes [therapy 1], [therapy 2], and [therapy 3].
OR
The majority of cases of [disease name] are self-limited and require only supportive care.
OR
[Disease name] is a medical emergency and requires prompt treatment.
OR
The mainstay of treatment for [disease name] is [therapy].
OR The optimal therapy for [malignancy name] depends on the stage at diagnosis.
OR
[Therapy] is recommended among all patients who develop [disease name].
OR
Pharmacologic medical therapy is recommended among patients with [disease subclass 1], [disease subclass 2], and [disease subclass 3].
OR
Pharmacologic medical therapies for [disease name] include (either) [therapy 1], [therapy 2], and/or [therapy 3].
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
- 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
- Preferred regimen (1):Tamsulosin 0.4 mg PO q24h until stone passage occurs or for up to 30 days[7]
- Preferred regimen (2):Used as adjuvant in Extracorporeal shockwave lithotripsy; Tamsulosin 0.4 mg PO q24h for 14 days to 3 months[8]
- Preferred regimen (3): Nifedipine 10-30 mg PO q8h for up to 4 weeks or until expulsion of lower stones[9]
Type specific treatment
Treating the underlying cause is very important.
- Calcium stones
- Treating primary hyperparathyroidism
- Treating Renal tubular acidosis
- For those having high urinary calcium:
- Preferred regimen (1): Hydrochlorothiazide 50 mg PO q24h[10]
- Alternative regimen (1): Chlorthalidone 25 mg PO q24h[10]
- For recurrent stones and high urine uric acid:
- Preferred regimen (1): Allopurinol 200-300 mg PO in single or divided doses
- For recurrent stones and hypocitraturia:[11]
- Preferred regimen (1): Potassium citrate 15 mEq extended release q12h in mild-to-moderate hypocitraturia (>150 mg urinary citrate); maximum dose: 100 mEq/day
- Alternative regimen (1): Potassium citrate 10 mEq extended release q8h
- Preferred regimen (2): Potassium citrate 30 mEq extended release q12h in severe hypocitraturia (<150 mg/day urinary citrate); maximum dose: 100 mEq/day
- Alternative regimen (2): Potassium citrate 20 mEq extended release q8h
- Uric acid stones
- Alkalinizing urine with potassium citrate[11]/potassium bicarbonate[12] as above[13]
- Preferred regimen (1): Allopurinol 200-300 mg PO in single or divided doses[13]
- Struvite stones
- Medical therapy is not of much help, although urease inhibitors can be given in urease +ve etiology
- Preferred regimen (1): Acetohydroxamic Acid 250 mg PO q6-8h for a total daily dose of 10 to 15 mg/kg/day; maximum dose: 1500 mg daily[14]
- Medical therapy is not of much help, although urease inhibitors can be given in urease +ve etiology
- Cysteine stones
Urologic consult
- The Urological consult is needed in the following:[15][16]
- Stone >10 mm in diameter
- Uncontrolled pain
- Anuria
- Acute kidney injury
- Acute abdomen features like nausea and vomiting
- Signs of sepsis
