If stones less than 7mm generally pass through spontaneously without surgical intervention...Medical treatment of nephrolithiasis involves supportive care and administration of agents, such as the following:
Excessive water intake or IV hydration,
Nonnarcotic analgesics ,
Oral/intravenous narcotic analgesics,
NSAIDS (eg, ketorolac, ketorolac intranasal, ibuprofen),
Antiemetics (eg, metoclopramide),
Antibiotics (eg, ampicillin, gentamicin, ticarcillin/clavulanic acid, ciprofloxacin, levofloxacin, ofloxacin) to reduce possible infections,
Alkalinizing agents (eg, potassium citrate, sodium bicarbonate): For uric acid and cysteine calculi
Alpha blockers (eg, tamsulosin, terazosin)...
