Pneumatic Lithotripsy Versus Laser Lithotripsy for Ureteral Stones

Abstract Introduction: Several different modalities are available for ureteral stone fragmentation. From them pneumatic and holmium: yttrium-aluminum-garnet (Ho: YAG) lithotripsy have supportive outcomes. In this study we studied ۲۵۰ subjects who had ureteroscopic pneumatic lithotripsy (PL) or laser lithotripsy (LL).Methods: Two-hundred fifty patients with ureteral stones underwent ureteroscopic lithotripsy (۱۱۵ subjects in the PL group, ۱۳۵ subjects in the LL group) from August ۲۰۱۰ to April ۲۰۱۶. The purpose of this investigation was to evaluate stone-free rate (SFR), mean operation time (MOT), mean hospital stay (MHS), stone migration and complications.Results: Two groups were similar in age, gender, mean size of stones, side of stone, and complications. There was a statistical difference in terms of SFR, stone migration and MHS in favor of the LL group (P ≤ ۰.۰۵, P ≤ ۰.۰۵ respectively), and MOT in favor of the PL group (P ≤ ۰.۰۵).Conclusion: Both the PL and LL techniques were effective and safe for ureteral stones, however a slightly higher SFR was found in the LL group.
