AIM: To compare the effectiveness of Stone Cone™, PercSys and lidocaine jelly instillation to prevent stone migration during ureterorenoscopy (URS). MATERIALS AND METHODS: One hundred patients who underwent URS for proximal ureteral stones between 2007 and 2012 were evaluated prospectively. The patients were divided into four groups consecutively. The control group (Group I) consisted of the 25 consecutive patients, in whom no device or method was used to prevent stone migration. Group II consisted of 25 patients treated with the Stone Cone, group III consisted of 25 patients treated with PercSys, and group IV consisted of 25 patients treated with lidocaine jelly instillation. RESULTS: The migration rates were 4.5% in group II, 8.7% in group III, 21.7% in group IV, and 31.8% in group I. The migration rate was found to be statistically significantly lower in the groups treated with the Stone Cone and PercSys compared to the control group (p = 0.014, p = 0.048). However, there was no statistically significant difference between the lidocaine jelly group and the control group in terms of migration rates (p = 0.444). CONCLUSIONS: Our results suggested that the Stone Cone and PercSys were the most successful methods with significantly low migration rates (4.5 and 8.7%, respectively).
