| Zusammenfassung: | Occlusion of internal ureteral stents commonly called double-J (DJ) stent leads to renal dysfunction, urinary tract infection, and difficulty in replacing the stent. We investigated the cause of stent occlusion and whether DJ stent occlusion persisted with change in the type of stent. The internal ureteral stent, Bird® Inlay™ Optima or Boston Scientific® Tria™, was inserted in 43 ureters of 33 patients who underwent replacement more than three times between September 2017 and June 2020. We defined stent occlusion as follows: a guide wire could not be passed through a stent during the replacement. In the first occlusion, the type of stent was changed. In the second occlusion, the stent placement interval was shortened from 12-13 weeks to 6-8 weeks. The presence of urinary stone and insertion of a urethral catheter had a high risk of DJ stent occlusion. Stent occlusion was observed in 20 of the 43 ureters. After the type of stent in 20 ureters with stent occlusion was changed, there were no DJ stent occlusions in 16 of the 20 ureters. Nevertheless, in 4 of the 20 ureters, even if we changed the type, DJ stent occlusion was still present; hence, the replacement interval was shortened. Therefore, changing the type of stent may be a recommended intervention for DJ stent occlusion |
