Registered outcomes5
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Decline in Estimated Glomerular Filtration Rate (eGFR) From Baseline to 3 Months After Surgery | Baseline and 3 months after surgery | eGFR will be calculated from serum creatinine measured before surgery and at the 3-month postoperative follow-up using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. The decline in eGFR will be calculated as preoperative eGFR minus postoperative eGFR and expressed in mL/min/1.73 m². A smaller decline indicates better preservation of kidney function. |
| Secondary | Estimated Intraoperative Blood Loss | Perioperative | Estimated blood loss will be calculated as the volume collected in the suction canister minus the volume of irrigation fluid, plus the blood loss absorbed by gauze, determined by weighing the gauze. The median estimated blood loss will be compared between the off-clamp, sutureless RAPN group and the conventional RAPN group. |
| Secondary | Surgical Completion Rate | Perioperative | Surgical completion will be assessed by recording the number of participants requiring conversion from: 1. Off-clamp, sutureless RAPN to conventional on-clamp, sutured RAPN; 2. Partial nephrectomy to radical nephrectomy; or 3. Minimally invasive surgery to open surgery. The surgical completion rate and conversion rates will be compared between the two groups. |
| Secondary | Negative Surgical Margin Rate | 1 week after surgery | The negative surgical margin rate will be determined based on the routine postoperative pathological examination of the resected specimen and compared between the two groups. |
| Secondary | Postoperative Complication Rate | up to 1 year | Postoperative complications graded as Clavien-Dindo grade II or higher will be recorded. The proportion of participants experiencing such complications will be compared between the two groups. |
