초록
Ureteroscopic removal of the stone is now popular for the management of the lower ureteral stone. A clinical study was performed on our 75 patients with lower ureteral stone treated with ureteroscopy. Of the 75 stone manipulations 62 (83%) were immediately successful and the final success rate including spontaneous delivery of stone or fragment after the procedure was 87 percents (65 cases). Of 57 smaller calculi than 1 cm (radiographic largest diameter) 50 (88%) were removed successfully. Mean duration of postoperative hospitalization was 5.6 days. There were no interrelations between the success rate and anesthetic methods. Significant complications during or after procedure were not identified. We conclude that ureteroscopic removal of stones under direct vision can be done safely and be the first choice of procedure for the lower ureteral stones.
