简要总结

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.

结局指标

主要结局

ureteral reflux

时间窗: Intraoperative

Injection of raradiopaque dye using gravity- filling cystogram followed by X-ray imaging. If contrast entered or not entered the ureter and kidney, ureteral reflux was considered positive or not, respectively.

Assessment the Ureteral Stent Symptom Questionnaire (USSQ)

时间窗: Postoperative: 1st and 7th day, before stent removal

Ureteral stent symptom questionnaire (USSQ) a psychometrically valid measure to evaluate symptoms and impact on quality of life of ureteral stents. USSQ contains 38 questions and 2 visual analog scales (VAS), allowing assessment of the severity of SRS and their impact on the patient's quality of life. The questions are grouped into 6 domains: Urinary symptoms Pain General health Work performance Sexual matters Additional problems For each domain, a score index is calculated as the sum of the points from all questions in that domain. The scale scores range from 1 to 10, with higher values indicating more severe SRS and lower quality of life.

次要结局

  • Patient's height(Preoperative)
  • Patient's weight(Preoperative)
  • Body mass index (BMI)(Preoperative)
  • Operative time(Intraoperative (measured from start to end of procedure))
  • Surgery(Preoperative)
