Summary

This is a prospective randomized controlled trial designed to assess the differences in postoperative symptoms related to placement of a 6Fr Percuflex ureteral stents, 6Fr Tria ureteral stents, 4.8Fr Percuflex ureteral stents, and 4.8Fr Tria ureteral stents after ureteroscopy with laser lithotripsy for treatment of upper tract urinary stones. 272 participants will be enrolled and will be on study for up to approximately 10 weeks.

  • Urinary Stone

Interventions

DEVICE

6Fr Percuflex ureteral stents

The Percuflex stent is a 6Fr polymeric, hydrophilic coated stent that is routinely used post ureteroscopy with laser lithotripsy.

DEVICE

6Fr Tria ureteral stents

The Tria stent is a new stent that is designed to soften at body temperature after placement, with an additional coating that prevents calcium and magnesium build up. This is intended to increase patient tolerability of the stent. 6 Fr is the diameter.

DEVICE

4.8Fr Tria ureteral stents

The Tria stent is a new stent that is designed to soften at body temperature after placement, with an additional coating that prevents calcium and magnesium build up. This is intended to increase patient tolerability of the stent. 4.8 Fr is the diameter.

DEVICE

4.8Fr Percuflex ureteral stents

The Percuflex stent is a 4.8Fr polymeric, hydrophilic coated stent that is routinely used post ureteroscopy with laser lithotripsy.
