[Treatment of reno-ureteral lithiasis with ESWL in obese patients. Apropos of 150 patients].

Objectives: Obesity is considered a significant risk factor for diseases such as hypertension, diabetes, coronary artery disease, and metabolic diseases, increasing considerably the risk for surgery. We have treated with ESWL a significant number of patients with the aim of avoiding operations which could be long and have associated complications due to the patient's condition.
