This randomized controlled trial evaluated the noninferiority of sutureless purely off-clamp robotic partial nephrectomy (SL-ocRPN) compared to renorrhaphy (RR-ocRPN) in patients with cT1-2N0M0 renal tumors. Among 248 patients, Trifecta was achieved in 93% of SL-ocRPN cases versus 95% for RR-ocRPN, meeting the noninferiority criterion (absolute difference -2.4%; 90% CI -7.4%-2.6%).
Key findings
- Trifecta achievement was 93% for SL-ocRPN and 95% for RR-ocRPN, meeting noninferiority criteria.
- Blood transfusion rates were 2.4% for SL-ocRPN and 0% for RR-ocRPN.
- Acute kidney injury occurred in 1.6% of both groups.
- One-year recurrence-free survival was 99% across all cohorts.
Why it matters
The findings suggest that sutureless robotic partial nephrectomy may be a safe and effective alternative to traditional techniques, potentially reducing postoperative complications and improving recovery for patients with renal tumors.
What to keep in mind
Limitations include the single-center design, reliance on a single surgeon's expertise, and short oncologic follow-up.
