Overview
Brief Summary
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.
Detailed Description
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.

Eligibility Criteria
Inclusion Criteria
- •Clinical diagnosis of unilateral ureteral stone
- •Plan to undergo unilateral URS lithotripsy
- •Adult patients (\>18 years old)
Exclusion Criteria
- •Pre-stented cases
- •Distal ureteral stones
- •Preoperative urinary tract infection
- •With medications known to influence stent-related symptoms, including alpha-blockers, antimuscarinics, beta3-agonist
- •Pregnancy

Outcomes
Primary Outcomes
Lower urinary tract symptom after placement of D-J stent
Time Frame: 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
Secondary Outcomes
- Pain after placement of D-J stent(Before removal of D-J stent)
