Geostone Procedure for Kidney/Ureteral Stones
I cannot identify a procedure beginning with "geo" that treats kidney or ureteral stones based on the available evidence and established urological terminology.
Standard Procedures for Kidney and Ureteral Stones
The evidence-based treatment options for kidney and ureteral stones include:
Primary Treatment Modalities
Ureteroscopy (URS) - The preferred surgical approach for most ureteral stones, achieving stone-free rates of 81-94% depending on location 1
Shock Wave Lithotripsy (SWL) - Non-invasive fragmentation using extracorporeal shock waves, with stone-free rates of 80-85% for stones <10mm 1, 2, 3
Percutaneous Nephrolithotomy (PCNL) - First-line therapy for renal stones >20mm, offering stone-free rates of 85-100% 1, 4
Alternative Surgical Approaches
Percutaneous antegrade ureteroscopy - Reserved for very large (>15mm) impacted proximal ureteral stones, with stone-free rates of 85-100% 1, 5
Laparoscopic ureterolithotomy - Used when SWL and URS have failed or are unlikely to succeed for large, impacted, or multiple stones 1
Common Pitfall
The term you're seeking may be a misremembered or colloquial reference. No established urological procedure beginning with "geo" exists in current guidelines 1, 6, 5. You may be thinking of:
- Percutaneous procedures (PCNL)
- Ureteroscopy with laser lithotripsy
- A regional or institutional term not reflected in standard nomenclature
