Title: Diagnosis and treatment of renal and ureteral calculi. Author: Knight J. Journal: Alaska Med; 1998; 40(2):27-30. PubMed ID: 9658656. Abstract: Nephrolithiasis affects about 0.2% of the US population annually with about 5% to 15% of the population suffering at some point in their lives. While 75% of all calculi are calcium based, the remainder are composed of uric acid, cystine, struvite, or are composed of more than one substance. A 1997 policy update by the American Urological Association recommends that stones lodged in the ureter that are not causing excruciating pain for the patient are best initially managed by observation.[Abstract] [Full Text] [Related] [New Search]
