Abstract

Objective：When performing flexible transurethral lithotripsy（f-TUL）, the placement of a safety guidewire（SGW）is generally recommended in the European Association of Urology guidelines 2013. <br>  We evaluated the necessity of placing an SGW. <br>  Patients and Methods：Between April 2012 and May 2013, we conducted 100 f-TUL procedures without and 24 with an SGW. <br>  We investigated the average size of stones, ureteral kinks, findings associated with calculi of the urinary tract, preoperative hydronephrosis, operative time, stone-free rate（SFR）, and complications. <br>  Results：There were no significant differences in either the mean operative time（with SGW：44.5 minutes vs. without SGW：37.5 minutes）or stone-free rate（with SGW：91.7% vs. without SGW：95.0%）. <br>  We tended to require placement SGW for patients with preoperative hydronephrosis, ureteral kinks or findings associated with calculi of the urinary tract. <br>  Conclusion：From this study, only a limited number of patients require SGW placement.
