Registered outcomes2
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Immediate Stone-Free Rate | Within 24 hours after surgery | The proportion of patients with no residual renal stone fragments or only clinically insignificant residual fragments, as defined in the study protocol, confirmed by postoperative imaging immediately after surgery. The immediate stone-free rate will be compared between the smart pressure-controlled flexible ureteroscopy group and the distal flexible suction ureteral access sheath-assisted flexible ureteroscopy group. |
| Primary | Postoperative Complication Rate | From surgery to 30 days after surgery | The proportion of patients experiencing intraoperative or postoperative complications associated with the surgical procedure, including infectious complications, ureteral injury, bleeding, and other adverse events. Complications will be assessed and graded according to the Clavien-Dindo classification. |
