Measure
Shockwave Lithotripsy (SWL)
All patients were submitted to a noncontrast computed tomography before to shockwave lithotripsy (SWL). Patients were submitted to SWL under the following conditions: outpatient, general anesthesia, 3000 impulses, rate of 90/min, discharged from hospital in the same day with alpha-blocker (doxazosin) during 30 days.
