简要总结
A thin tube, called a ureteral stent, is inserted into the ureter and is commonly used as treatment of urinary stone disease. Stents are designed to help provide drainage of the kidney in the setting of an obstructing stone, or postoperative swelling of the ureter. Though their presence is only temporary, stents are associated with a significant amount of patient discomfort and bother, which can negatively impact overall satisfaction. Over the past decades, there have been refinements in stent technology and usage philosophy. Smaller and softer stents are now available for use in patients, though studies evaluating the relative benefits have been conflicting. The investigators aim to evaluate the effect of stent size and composition upon outcomes after the treatment of stone disease, including patient comfort and satisfaction.

入选标准
- •Over 18 years of age and willing and able to provide informed consent
- •Patients with current urinary stone disease, undergoing any of the following procedures:
- •cystoscopy with stent placement
- •ureteroscopy with intracorporeal lithotripsy
排除标准

结局指标
主要结局
Change From Baseline in Pain on the 10-point Analog Pain Scale at Day 7 Post Stent Removal.
时间窗: Baseline, day 7 post stent removal
The 10-point scale ranges from 0 (zero) for no pain (minimum) to 10 for the worst possible pain (maximum). The unit of measure is 1 point on the 10-point scale.
