Renal lithiasis: a practical approach.

Management of most patients with calculous disease has been less than ideal in the past. Too often therapeutic efforts were limited to symptomatic calculi. Stones were allowed to pass or were removed, metabolic studies were incomplete, victims were dismissed and forgotten, and prophylactic measures were negligible and usually confined to milk restriction and use of distilled water. More patients were crippled with and died of recurrent calculous disease, urinary infection and progressive renal insufficiency than from any other upper urinary tract abnormality. During the last decade the development of a renal stone clinic at this institution has allowed a nephrourologic approach to the management of urolithiasis. This account of classification, diagnosis and management of the various syndromes associated with urolithiasis is based on the experiences gained during the last decade with this common but ill-understood urologic problem.
