Hi, As in most of people the kidney stone give rise no symptoms so remain undiagnosed through out life, but in those with symptoms present with pain during urination, flank pain, frequency and urgency etc. Small stones need only pain management through NSAIDs and intake of plenty of water. But large stones need removal by various processes like Extracorporeal shock wave lithotripsy (a non invasive procedure ), surgical process like Ureteroscopic surgery by using laser/ basket extraction, percutaneous nephrolithotomy. Thank you for consulting HCM.
