About this trial
Double-J (DJ) stents are commonly inserted after ureteroscopy. There are several complications associated with the presence of DJ stent: urinary tract infection, stent encrustation, stent migration, and stent-related symptoms (SRS).
SRS occur in up to 80% of patients and include pain, hematuria, and dysuria, all of which negatively impact the patient's quality of life.
Physicians proposed the distal end of the ureteral stents might involve in SRS by over-simulating the trigone of bladder. The design of the distal end, made with a thinner loop than that of a standard DJ stent, is intended to mitigate SRS and reduce urine reflux.
