Effectiveness and safety of ultra-slow full power shockwave lithotripsy compared to mini–percutaneous nephrolithotomy and retrograde intrarenal surgery for treatment of lower calyceal stone between 1 and 2 cm with high attenuation value
To compare the effectiveness and safety of ultra-slow full-power shockwave lithotripsy (SWL), mini-percutaneous nephrolithotomy (mini-PNL), and retrograde intrarenal surgery (RIRS) for 1-2 cm lower calyceal stones with Hounsfield units (HU) > 1000.
Key Findings:
Ultra-slow SWL showed improved stone-free rates (specific percentage) for high attenuation stones without compromising safety.
Mini-PNL achieved higher single-session success rates (specific percentage) but posed risks of bleeding and organ injury.
RIRS provided a balance of effectiveness (specific percentage) and safety, especially for complex renal anatomy.
Interpretation:
The study suggests that ultra-slow SWL may be a viable alternative for treating high-density lower calyceal stones, potentially offering a safer option compared to more invasive procedures, with significant implications for clinical practice.
Limitations:
The study was conducted at a single institution, which may limit generalizability and introduce potential biases.
Long-term outcomes and complications were not extensively evaluated.
Conclusion:
Ultra-slow full-power SWL is effective and safe for treating lower calyceal stones with high attenuation values, presenting a promising alternative to mini-PNL and RIRS, with important implications for patient management.
