Evaluation of Quality of Life in Patients After Placement of a Modified Double J Ureteral Stent
Evaluation of Quality of Life in Patients After Placement of a Modified Double J Ureteral Stent. Randomized Clinical Trial.
St. Luke's Clinical Hospital, Russia
40 participants
Dec 28, 2025
INTERVENTIONAL
Conditions
Summary
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.

Interventions
Ureteric stent insertion is the procedure to place a thin, flexible plastic tube that is temporarily in the ureter to help urine drain. They are placed with cystoscopic and X-ray guidances in an operating room setting
