Yakupoglu, Yarkin Kamil/0000-0002-4764-0289; Ozden, Ender/0000-0003-3196-4024 WOS: 000308813800011 PubMed: 22160282 Forgotten ureteral stents represent a difficult problem for urologists; the major complications are infection, migration, encrustation, stone formation, and multifractured stent, and a consensus on the best therapeutic approach is lacking. Here we present our experience with endoscopic management of this challenging problem and discuss the various endourological approaches for treating forgotten encrusted ureteral stents. From January 2005 to December 2010, 19 patients (11 women and 8 men) with encrusted ureteral stents were retrospectively analyzed. Combined endourologic therapies including extracorporeal shock wave lithotripsy (SWL), percutaneous nephrolithotomy (PCNL), ureterorenoscopic lithotripsy (URSL), and cystolithotripsy (CLT) were used to achieve stent removal. A total of 19 patients with encrusted ureteral stents were treated at our center. The mean patient age was 46.2 +/- A 18.5 years (8-81), the average indwelling time of the stent was 24.7 +/- A 19.0 months (8-93), and the mean hospital stay was 3.4 +/- A 4.0 days (range 1-15 days). Using the described combination of techniques, all stents and the associated stones were eventually removed without any complications and patients were rendered stone- and stent-free. A main element of the treatment strategy was to keep the number of interventions as low as possible. The use of various combinations of endourological techniques can achieve effective stent and stone treatment after a single anesthesia session with minimal morbidity and short hospital stay.

(Urol Res, doi: 10.1007/s00240-012-0476-0 , 2012) about the impact of the intentional ureteral stenting on the success rate of calculus extraction by second ureteroscopy, when the initial ureteroscopy failed. Actually, sometimes ureteral stone treatment pose challenging problems for the urologists. This study has filled an important gap on this field. If flexible ureteroscopy and laser lithotripter are not available pre-existing stent may improve the success rate of a subsequent ureteroscopy for impacted ureteral stones. Because, post-stent ureteroscopy has the advantage of working through a dilated ureter. We would like to add some additional comments and suggestions in addition to the authors' discussion, which is noteworthy in several respects.
