Summary
Zero ischemia robotic partial nephrectomy (RPN) is a safe procedure for small renal tumors, demonstrating good functional and oncological results with minimal complications. This technique offers acceptable outcomes for selected larger tumors as well.
Area of Science:
- Urology
- Surgical Oncology
- Minimally Invasive Surgery
Background:
- Robotic partial nephrectomy (RPN) is a key procedure for renal tumors.
- Zero ischemia techniques aim to improve functional outcomes.
- Evaluating the safety and efficacy of zero ischemia RPN is crucial.
Purpose of the Study:
- To assess the functional and oncological outcomes of zero ischemia robotic partial nephrectomy (RPN).
- To evaluate complications and renal function changes following the procedure.
Main Methods:
- Prospective data collection from 56 patients undergoing transperitoneal zero ischemia RPN.
- Assessment of R.E.N.A.L. nephrometry and PADUA scores.
- Evaluation of intraoperative and perioperative complications (Clavien classification) and renal function (serum creatinine, eGFR).
Main Results:
- No intraoperative complications; low perioperative complication rate (2 patients).
- No significant changes in eGFR or serum creatinine post-surgery.
- Tumor size averaged 3.1 cm; positive margins in 2 patients with no recurrence or metastasis during follow-up (mean 33.6 months).
Conclusions:
- Zero ischemia RPN is a safe and effective method for small renal tumors.
- It provides acceptable oncological and functional outcomes.
- The technique is also applicable to selected larger renal tumors.
