Novel stone retrieval devices have been introduced to address the problem of accidental stone migration: Stone baskets, suction devices, balloon catheters guidewire and gel-based devices significantly reduced the incidence of stone retropulsion. shockwave lithotripsy (SWL), flexible ureterorenoscopy (fURS)) with affiliated morbidities and health-care costs have been reported.

Hereby an increase in operative time, a decrease in stone-free rates and the need for further auxiliary procedures (i.e. Stone migration occurs in 28вЂ“60% of proximal calculi. A particular challenge limiting the success of ureteroscopic lithotripsy is stone retropulsion due to insertion of the ureteroscope, pressure by the irrigation fluid and/or the lithotripsy itself. Ureterorenoscopy (URS) with and without lithotripsy is a standard method to treat ureteral calculi depending on different factors including location, stone size, individual patient factors as well as equipping. The вЂњGuidewire-Coil-TechniqueвЂќ is a simple and safe procedure that may help to prevent proximal calculus migration and therefore may increase stone-free rates without causing additional costs.Дuring the past two decades, there have been many improvements regarding the endoscopic treatment of urolithiasis. One ureteral injury in the control group required a prolonged ureteral stenting. No difference was observed in operative time. 8/28, pвЂ‰<вЂ‰0.05) as well as a decreased use of auxiliary procedures ( pвЂ‰<вЂ‰0.05) compared to the control group. There has been a statistically significant reduction of accidental stone retropulsion (2/27 vs. Twentyseven patients underwent semirigid ureterorenoscopy using the вЂњGuidewire-Coil-TechniqueвЂќ, the second group ( nвЂ‰=вЂ‰28) served as control group using the guidewire as usual. The study population consisted of 55 patients with 61 mid-to-proximal calculi. The preoperative stone burden was routinely assessed using low dose CT scan (if available) and/or intravenous pyelogram. We retrospectively evaluated all patients with mid-to-proximal ureteral stones in 2014, which were treated by ureteroscopic lithotripsy (Ho: YAG and/or pneumatic lithotripsy). We present the simple technique of using a coil of the routinely used guidewire to prevent stone retropulsion.

The use of additional tools to prevent proximal stone migration entails further costs and risks for ureteral injuries. The consequences are an increased duration and cost of surgery as well as decreased stone-free rates. Stone retropulsion represents a challenge for intracorporeal lithotripsy of ureteral calculi.
