About

Patients who underwent retrograde intrarenal surgery (RIRS) were randomly allocated to general anesthesia (GA) or spinal anesthesia (SA) groups. Renal function was assessed using estimated glomerular filtration rate, and relative renal function was evaluated using nuclear medicine tests. Maneuverability and accessibility were evaluated after every surgery. We analyzed the influence of anesthesia methods on surgical outcomes and renal function in retrograde intrarenal surgery in a prospective, randomized controlled study.
