Nephrolithiasis

The process of forming a kidney stone, a stone in the kidney. Kidney stones are a common cause of blood in the urine and pain in the abdomen, flank, or groin. Kidney stones occur in 1 in 10 people at some time in their life.The development of the stones is typically related to increased excretion of stone-forming components such as calcium, oxalate, urate or cystine.The pain with kidney stones is usually of sudden onset, very severe and colicky, not improved by changes in position, radiating from the back, down the flank, and into the groin. Nausea and vomiting are common.Treatment includes relief of pain, hydration and, if there is concurrent urinary infection, antibiotics.
