title: Extracorporeal shock-wave lithotripsy.
abstract: Analysis of our data clearly demonstrates that morbidity, secondary treatment, post-treatment manipulations, and failure of treatment increase as the stone size increases because of the increased stone fragment burden. Patients whose stone burden was less than 2 cm clearly had less morbidity. Composition of the stone may also alter the success of treatment (with cystine, calcium oxalate monohydrate, and brushite stones being resistant to treatment). However, post-treatment morbidity and complications were observed in all categories. Perirenal hematomas are unpredictable by current preoperative testing. Obstruction with pain can occur any time after treatment but usually occurs within the first 48 hours in the majority of patients. Only 1 per cent of our patients required hospitalization in another institution after discharge. Ambulatory ESWL requires that staff at the facility or a urologist be able to observe and appropriately follow the patient for 24 to 48 hours after treatment.
