Brief summary

This is a multicenter prospective trial with randomized and observational cohorts assessing patient-reported outcomes and unplanned healthcare utilization following ureteroscopic treatment of renal and ureteral stones, with placement versus omission of a ureteral stent. Eligible participants in the randomization trial will be randomized to ureteroscopy with stent placement or stent omission. Eligible participants that consent to the observational only cohort will complete surveys and the treating physicians will decide the treatment options for the participants. The study team hypothesizes that: * Pain interference change from pre-surgery to Day 7-10 will differ between the two treatment arms. This hypothesis will be evaluated separately in the randomized and observational cohorts. * Unplanned healthcare utilization in the treatment arms will have different unplanned healthcare utilization ranks leading to a win proportion significantly higher or lower than 0.5 in the stent omission arm compared to the stent placement arm. This hypothesis will be evaluated separately in the randomized and observational cohorts.

Detailed description

The coordinating center for this study is the Michigan Urological Surgery Improvement Collaborative (MUSIC), which is a physician-led Quality Improvement (QI) collaborative comprised of 44 urology practices and 260 urologists across the State of Michigan. As sites are activated the registration will be updated.

Interventions

DEVICEStandard of care stent placement

Participants will have a stent placed per randomization assigned if there are no complications (per protocol) during ureteroscopy that excludes the participant.

OTHERNo stent placement

Participants not have a stent placed per randomization assigned if there are no complications (per protocol) during ureteroscopy that excludes the participant.

OTHERSurveys

All participants in the trial cohort and observational arms will be asked to complete survey instruments (evaluating their pain, quality of life, and experiences following ureteroscopy, as well as surveys evaluating their opinions and preferences around ureteral stenting, etc.). Participants will also have routine clinical data (preoperative, perioperative, and postoperative) to be collected and analyzed for research purposes.

SINGLE (Caregiver)

Masking description

Surgeons will remain blinded to this allocation until the surgeon has confirmed secondary eligibility.

Intervention model description

Participants that consent for the randomization cohort (264 anticipated) will be randomized using an online computer-based system to either stent omission or stent placement in a 1:1 ratio following secondary eligibility criteria. Blocked, stratified randomization based upon surgeon classified stone location (renal only versus ureteral with or without renal), with random block sizes will be used to ensure group balance. Observational study participants (528 anticipated) will not be randomized.

Inclusion criteria

* Undergoing unilateral ureteroscopy and lithotripsy for stone disease (participants may have contralateral stones, as long as these are asymptomatic and not being treated concurrently) * Largest stone less or equal to 10 millimeter in size as measured on abdominal x-ray, ultrasound, or computed tomography scan * Access to means of communication with the study team (email, text messaging, and/or telephone) * Adequate independent cognitive function and English language proficiency to complete study surveys * Written informed consent

Exclusion criteria

* Planned bilateral ureteroscopy * Indwelling ureteral stent or percutaneous nephrostomy tube preoperatively in either kidney * Anatomic abnormalities of the ipsilateral upper urinary tract (for example, horseshoe kidney, crossed fused ectopia, pelvic kidney, urinary diversion) * Anatomic or functional solitary kidney * Planned secondary or staged ureteroscopy * Planned use of ureteral access sheath * Pregnancy * Patients who use opiate medication daily for greater than 3 months to manage a painful condition Second Stage

MeasureTime frameDescription
Patient Reported Outcomes Measurement Information System (PROMIS®) Pain Interference (Short Form 6b) change at Postoperative Day 7-10 compared to preoperativePreoperative, Day 7-10This survey has 6 questions that participants select from 1(not at all) to 5 (very much) for questions 1-5 related to pain interference. For question 6 participants select from 1 (Never) to 5 (Always). There are total of 6-30 points where the higher the score the more pain interference.

International Consultation on Incontinence - Satisfaction (ICIQ-S) treatment satisfaction scores at postoperative day 7-10Postoperative day 7-10Participants will complete this 14-question survey regarding satisfaction of treatment. The ICIQ-S assesses aspects of experience, expectations, and outcomes to evaluate satisfaction after urological surgery. A scoring system has been derived that consists of two parts: a score for the evaluation of satisfaction with 'surgical outcomes' (ICIQ-S outcome score, range 0-24); and the overall satisfaction with surgery item, scored 0-10. Higher scores indicate more satisfaction.
