Registered outcomes8
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Complete TZ-RIRS Success | Intraoperative (during the surgical procedure) | Completion of the surgical procedure without intraoperative fluoroscopy, without rescue ureteral access sheath (UAS) placement, and without a preoperative stent. |
| Secondary | Stone-Free Rate (≤4 mm) | 3 months postoperatively | Proportion of patients with no residual stone fragments greater than 4 mm on non-contrast CT. |
| Secondary | Stone-Free Rate (≤2 mm) | 3 months postoperatively | Proportion of patients with no residual stone fragments greater than 2 mm on non-contrast CT. |
| Secondary | Stone-Free Rate (Zero Fragments) | 3 months postoperatively | Proportion of patients with zero residual stone fragments on non-contrast CT |
| Secondary | Operative Time | Intraoperative | Total duration of the surgical procedure in minutes, measured from ureteroscope insertion to completion. |
| Secondary | Complications | Up to 3 months postoperatively | Intraoperative and postoperative complications graded by the Clavien-Dindo classification system. |
| Secondary | Reintervention Rate | Up to 3 months postoperatively | Proportion of patients requiring a secondary surgical intervention (e.g., second RIRS, shockwave lithotripsy, or PCNL). |
| Secondary | Radiation Exposure | Intraoperative | Fluoroscopy time (minutes) and radiation dose (mGy) recorded for patients requiring intraoperative conversion to fluoroscopy, compared with conventional RIRS. |
