Semirigid Laser Ureterolithotripsy for Single Large Renal Pelvic Stones

Abstract

Background and purpose: Large stones located at the renal pelvis are usually managed with Percutaneous Nephrolithotomy (PCNL); however this procedure carries both a substantial morbidity and a considerable risk for complications. Our objective was to assess the safety and efficacy of semirigid ureteroscopy (S-URS) and laser lithotripsy for the treatment of single large (>1.5 cm) pelvic stones.
