COMPARISON OF URETERIC STONE MIGRATION AND FRAGMENTATION WITH AND WITHOUT STONE CONE
Aims And Objectives: To compare the safety and efficacy of ureteroscopic pneumatic lithotripsy with use of stone
cone and without stone cone
Methodology: This study was undertaken at Department of urology Lady Reading hospital Peshawar. This was a
comparative study. A total of fifty patients were enrolled during the study period. All the patients were randomized into
two groups. The total duration of this study was nine from Feb 2015 to Nov 2015.All adult males and females of age
>18 years and above with single ureteric stone were included in the study. Patients with ureteral stricture, concomitant
renal stone and failed ureteroscopy were excluded from studies
Results: During the study period from, Feb2015 to Nov 2015, a total of fifty patients were divided into two groups with
25 in each group. In the first group stone cone was used in which the stone clearance rate was 100%.
Conclusion: It is concluded from my study that the Stone Cone is safe and efficient in preventing proximal stone migration
during ureteroscopic pneumatic lithotripsy.
Key Words: Stone cone, Lithotripsy, ureterorenoscopy
