ABSTRACT
Between January 1990 and February 1991, ureteroscopic removal of ureteral stone was performed in 40 cases at outpatient department under local anesthesia(36 cases) and epidural anesthesia(4 cases). The results were as follows. The success rate of ureteral stone removal was 82.1% (32 among 39 cases) in lower ureter, 86.7 %(26 among 30 cases) in female and 70.0%(7 among 10 cases) in male. Anesthetic methods were local(36 cases), and epidural(4 cases), Mean duration of hospitalization was 1.4 days(0-7 days). The associated complication rate was low, with most patients being treated conservatively. Therefore, we believe that the ureteroscopic stone removal at outpatient department can be done safely if we select patients properly(especially women). have adequate equipment and execute properly the basic technique.
