This systematic review and Bayesian network meta-analysis evaluated the efficacy and safety of suction-assisted ureteroscopy techniques (FANS and DISS) for renal stones ≤ 2 cm in 3,657 patients. The study found that FANS significantly improved the stone-free rate (SFR) with an odds ratio of 2.5, while also reducing postoperative complications and fever compared to traditional methods.
Key findings
- FANS demonstrated a higher stone-free rate (SFR) with an odds ratio of 2.5.
- FANS reduced postoperative fever and complications compared to traditional methods.
- DISS showed a similar but less precise effect on SFR with an odds ratio of 3.1.
- FANS had lower odds of postoperative sepsis (OR 0.40).
Why it matters
Improving stone-free rates and reducing complications are critical for enhancing patient outcomes in urological procedures. This analysis provides evidence supporting the use of suction-assisted techniques in managing renal stones.
