Kim, Joon Heon; Han, Young Taik

Abstract

The cystoscopic manipulation was applied in 38 cases of lower one third ureteral stone who visited the Department of Urology National Police Hospital during the period from January 1979 to August 1981. 1. The age distribution was between 17 and 57 years, showing the highest incidence in 21 to 30 years (36.8%). 2. In 38 cases of stones in the lower one third of ureter in which the woven loop stone dislodger was used, the stone was removed successfully in 29 cases, a success rate of 76.3%. 3. Among 29 cases, 20 ureteral stones were extracted immediately and 9 ureteral stones were delivered spontaneously after cystoscopic manipulation. 4. In 7 cases (18.4%) ureterolithotomy was necessary. 5. The commonest size of stone extracted by woven loop stone dislodger was from 5 mm to 7 mm in size. 6. No specific complication were found during or after cystoscopic manipulations.
