简要总结
This is a prospective randomized clinical trial, evaluating the effect of the intra-ureteral placement of the stent's distal end versus the conventional stent placement on the postoperative LUTS and pain.
详细描述
Intravesical stent mass has been considered to cause stent-related symptoms, such as LUTS and pain. The current study hypothesized that the total intra-ureteral placement of the stent's distal end could decrease postoperative LUTS and pain. We proposed a prospective randomized trials, investigating the effect of intra-ureteral stent placement versus conventional stent placement. The primary end point was postoperative LUTS. The secondary end points were postoperative pain and quality of life. We used USSQ questionnaire as the assessing tool.

结局指标
主要结局
Lower urinary tract symptom after placement of D-J stent
时间窗: Before removal of D-J stent
The symptoms are evaluated by a complete USSQ (Ureteral Stent Symptom Questionnaire) urinary index. The minimum and maximum values are 11 and 53, and the higher scores mean a worse outcome
次要结局
- Pain after placement of D-J stent(Before removal of D-J stent)
