About this trial

This is an interventional other trial for Urinary Stones

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  1. Over 18 years of age and willing and able to provide informed consent
  2. Patients with current urinary stone disease, undergoing any of the following procedures:

    • cystoscopy with stent placement
    • ureteroscopy with intracorporeal lithotripsy

Exclusion Criteria:

  1. Patients with compromised urinary tract due to cancer (e.g. bladder tumor, ureteral obstruction from non-GU malignancy)
  2. Patients requiring bilateral surgical stone management procedure
  3. Patients with any single stone exceeding 1.5 cm
  4. Patients with severe concurrent disease, infection, or co-morbidity that, in the judgment of the investigator, would render the patient inappropriate for enrollment
  5. Any patient who is on anticholinergic medication at baseline

Outcomes

Primary Outcome Measures

Change From Baseline in Pain on the 10-point Analog Pain Scale at 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.

5. Study Description

Brief Summary
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.
