Outcome Measures

Primary Outcomes (1)

  • Lower urinary tract symptom after placement 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

    Before removal of D-J stent

Secondary Outcomes (1)

  • Pain after placement of D-J stent

    Before removal of D-J stent

Study Arms (2)

The intraureteral placement of distal end of ureteral stent

EXPERIMENTAL

Patients randomized to this group received 5-16/5-18 D-J stent with intraureteral placement of the distal end

Device: Ureteral Stent of 5-16 or 5-18

The conventional placement of the distal end of ureteral stent

ACTIVE COMPARATOR

Patients randomized to this group received 5-22/5-24 D-J stent with bladder placement of the distal end

Device: Ureteral Stent of 5-22 or 5-24

Interventions

Boston Scientific Polaris™ Ultra Ureteral Stent

The intraureteral placement of distal end of ureteral stent

Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Clinical diagnosis of unilateral ureteral stone
