Summary

This trial will assess patient-reported outcomes and unplanned healthcare utilization after ureteroscopic treatment of kidney stones, with or without a stent. Patients will be randomized or surveyed & treated at doctor's discretion.

Who is the study for?
This trial is for individuals undergoing ureteroscopy and lithotripsy for kidney stones no larger than 10mm, who can communicate with the study team and complete surveys in English. It excludes those with certain anatomical abnormalities, chronic opiate users, pregnant women, or those with a solitary kidney.
What is being tested?
The trial examines patient outcomes after kidney stone removal by comparing two approaches: one where a stent is placed post-surgery versus one without stent placement. Participants will either be randomly assigned to a treatment or observed based on physician's choice.
What are the potential side effects?
Potential side effects may include discomfort from the stent if placed, pain at the surgical site, urinary symptoms like urgency or frequency, and possible need for unexpected medical care related to the procedure.

Trial Design

3Treatment groups
Experimental Treatment
Group I: Randomized cohort- Stent placementExperimental Treatment2 Interventions
Participants that are eligible and consent for the randomization cohort trial will have a stent placed. If participants are found to be ineligible (see below) at the end of ureteroscopy the participants will not be randomized and taken off the study. In randomization cohort, second stage eligibility criteria: ureteral perforation, unanticipated anatomic abnormality, greater than expected bleeding, ureteral dilation greater than 12 French, ureteral access sheath utilized, failed ureteroscopy, no or incomplete lithotripsy performed, unable to complete case due to medical or anesthetic event.
Group II: Randomized cohort- No stent placementExperimental Treatment2 Interventions
Participants that are eligible and consent for the randomization cohort of the trial will not have a stent placed. If participants are found to be ineligible (see below) at the end of ureteroscopy the participants will not be randomized and taken off the study. In randomization cohort, second stage eligibility criteria: ureteral perforation, unanticipated anatomic abnormality, greater than expected bleeding, ureteral dilation greater than 12 French, ureteral access sheath utilized, failed ureteroscopy, no or incomplete lithotripsy performed, unable to complete case due to medical or anesthetic event.
Group III: Observational participants - not randomizedExperimental Treatment1 Intervention
Patients that do not consent to the randomization trial that elect to be on the observational cohort. Stent placement in the observational cohort will be decided by the surgeon intraoperatively, as per routine clinical practice.
