About this study

The study is being completed to compare patient reported outcomes for stent omission vs. placement after using a ureteral access sheath for uncomplicated ureteroscopy. Participants that consent for the study will complete baseline PRO questionnaires. A UAS will be used during surgery, and the size left to the discretion of the surgeon. At the end of the procedure, the urologist will evaluate the ureter for iatrogenic injury, and the ureter will be graded using the Post Ureteroscopic Lesion Scale (PULS). Patients assessed with PULS 0 and PULS 1 will meet 2nd stage eligibility and will be randomized 1:1 to either stent omission or stent placement. When a stent is placed, the stent type and decision to leave a string (tether) will be at the operating urologist's discretion. Hypothesis: \- stent omission arm will be non-inferior to stent placement in Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference and Pain Intensity, and have lower 30-day healthcare utilization.
