This systematic review and meta-analysis evaluated the efficacy and safety of papillary versus non-papillary access in 856 patients undergoing percutaneous nephrolithotomy (PCNL). The analysis found no significant differences in key perioperative outcomes, including hemoglobin drop and transfusion rates, suggesting both techniques are comparably effective.
Key findings
- No significant difference in hemoglobin drop between papillary and non-papillary access (MD 0.09 g/dL).
- Transfusion rates were similar for both access methods (OR 1.28).
- Operative duration did not significantly differ (MD 2.81 min).
- Stone size was identified as a significant moderator affecting operative duration.
Why it matters
Understanding the comparative outcomes of access techniques in PCNL can guide clinicians in making individualized decisions based on patient-specific factors, potentially improving surgical efficiency and patient safety.
