Abstract:
Ureteroscopic extraction has been used for the management of the ureteral stone. especially lower ureteral stone. During the last 2 years we performed ureteroscopy for removal of mid or distal ureteral stones in 63 patients. The causes of failure consisted of 4 unskillful instrumental manipulations, 4 migrations, of the stone. 3 failure of dilating ureter. 3 failures of access to the stone and 2. severe bleedings due to ureteral avulsion. The failure rate decreased from 33.3% for 30 procedures done during the first one year to 18.7 % for 33 procedures done in the next one year. We believe that the failure rate of ureteral stone removal will be consistently decreased with experience.
