Overview

Kidney stones can be due to underlying metabolic conditions, such as renal tubular acidosis, Dent's disease and medullary sponge kidney. Many health facilities will screen for such disorders in patients with recurrent kidney stones. This is typically done with a 24 hour urine collection that is chemically analyzed for deficiencies and excesses that promote stone formation.

Causes

Common Causes

The common causes of nephrolithiasis:

• Hypercalcemia
  • Hyperparathyroidism
• Hypercalciuria
• Infection with urea splitting microorganisms like Proteus and Pseudomonas
• Dehydration
• Inflammatory bowel disease

Less Common Causes

Less common causes of nephrolithiasis include:

• Drugs:
  • Loop diuretics
  • Acetazolamide
  • Ciprofloxacin
  • Indinavir
  • Triamterene
  • Cobicistat
  • Febuxostat
  • Ixabepilone
  • Oxcarbazepine
  • Pramipexole
  • Sulfasalazine
  • Tocilizumab
  • Topiramate
