To decrease ureteral stent-related symptoms, loop type ureteral stent was developed. However the most important factor to decrease urinary symptoms is choosing the optimal length of a ureteral stent. We investigated the relationship between the actual ureteral length and the loop type ureteral stent position. <i>Materials and Methods:<\/i> A total of 226 loop type polyurethane ureteral stents (156 patients) were inserted with four options for stent length (20, 22, 24 and 26 cm). The ureteral length was measured using a ruled 5-Fr ureteral catheter. The appropriateness of stent position was defined into three groups based on kidney-ureter-bladder films. <i>Results:<\/i> Nine stents (3.9%) migrated, 171 stents (75.7%) were in the appropriate position and 46 stents (19.5%) were overlong. The rate of migration rate and overlong stents closely correlated with the ureteral length when the proximal end of the stent was in the renal pelvis. <i>Conclusions:<\/i> It is appropriate to choose a loop type ureteral stent that is the same or 1 cm less than the length of the ureter when the proximal end of the stent will be in the renal pelvis.<\/jats:p>","DOI":"10.1159\/000332431","type":"journal-article","created":{"date-parts":[[2011,11,21]],"date-time":"2011-11-21T02:46:48Z","timestamp":1321843608000},"page":"48-53","source":"Crossref","is-referenced-by-count":26,"title":["Choosing
