One hundred and twenty-one patients with renal and ureteral stones were treated by extracorporeal shock wave lithotripsy (ESWL) from August 4 to October 31, 1986. Of them, 84 were free of stone. Promotion factor of stone passage after ESWL was studied in these stone free patients. No statistic difference was found in the sexual study and the study of stone analysis. Longer days were spended to passage stone with renal stones with maximum diameter of more than 2.1cm. There was no statistic difference in the size of the ureteral stones. Distigmine bromide (promoter of peristalsis of the urinary tract) accelerateel the passage of stones more than scopolmine-N-butylbromide (inhibitor of peristalsis of the urinary tract). Renal stones, especially those in the lower calix, spended more days for passage than ureteral stones because of their high localization and low pressure of peristalsis. The period of stone passage became less when the urine volume became more with renal stones while the period of stone passage was not influenced by the urine volume with ureteral stones.
