Registered outcomes5
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Success rate of separating and identifying the upper left ureter within 5 minutes | Intraoperative (Evaluated within 5 minutes during the specific surgical step) | The proportion of patients in whom the upper left ureter (up to the level of the left renal vein or the intersection of ovarian vessels) is successfully and clearly exposed without surrounding tissue obstruction, meeting the visual requirements for subsequent safe lymph node resection. The procedure is timed via video recording. The start time is when the surgeon's finger enters the space after the lower left ureter is identified; the end time is when the upper left ureter is completely exposed and visually confirmed by the surgeon. |
| Secondary | Incidence of left ureter complications | Intraoperative and up to 30 days postoperatively | The proportion of patients experiencing left ureter injuries. This includes intraoperative macroscopically visible ureteral contusion or rupture, and postoperative complications occurring within 30 days due to ischemia or injury, such as ureterovaginal fistula or ureteral stricture. |
| Secondary | Incidence of adjacent vessel or organ injury | Intraoperative | The rate of collateral damage occurring during the "One-Finger Technique" dissection that requires additional suturing or repair, such as adjacent vessel tearing/bleeding or bowel serosal tearing. |
| Secondary | Blood loss during the target step | Intraoperative (Assessed immediately after the completion of the specific surgical step) | The estimated local blood volume lost specifically during the single process of dissecting and identifying the upper left ureter. Because this step is brief and bleeding is usually minimal, it is recorded using visual estimation. |
| Secondary | Conversion rate to traditional methods | Intraoperative | The proportion of cases where the "One-Finger Technique" is abandoned in favor of traditional direct sharp dissection due to severe local adhesions, unclear anatomy, or high pushing resistance. This reflects the clinical applicability of the technique. |
