Answer
1) Stones < 5mm: conservative management (75% will pass spontaneously within 2 weeks)
2) Medical Expulsive Therapy (MET):
--α blocking agents (tamsulosin) increase the chance of spontaneous stone passage by 20 to 30%
3) Uric acid stones – alkalinization of urine to pH 6.5 to 7 (with sodium bicarbonate or potassium citrate)
4) Urological therapy for those that fail conservative and medical therapy (shockwave lithotripsy, ureteroscopy)
