About this trial
The impact of anesthesia type on Retrograde Intrarenal Surgery (RIRS) outcomes remains a subject of ongoing debate. Several studies have compared general anesthesia (GA) and spinal anesthesia (SA) in endourological procedures, with conflicting results regarding operative time, complication rates, and stone-free outcomes. Importantly, the interaction between anesthesia type and stone characteristics-particularly stone size-has not been fully elucidated. Therefore, this study aims to conduct a retrospective comparative analysis of general versus spinal anesthesia in patients undergoing RIRS at Qena University Hospital, with particular emphasis on the effect of stone size stratification on perioperative outcomes.

Trial outcomes
Primary outcomes
1
Stone Free Rate
Follow-up Ultrasound/Computed Tomography (US/CT) to assess stone-free status after the first postoperative month. Success was considered as residues of \<2mm or absence of any stone fragments.
Time frame
after the first postoperative month.2
Total opioid consumption
Total opioid consumption in the whole postoperative period is recorded
Time frame
PerioperativeSecondary outcomes
1
Pain assessement
pain is assessed uing Numerical Rating Scale where patients are asked to select a number from 0 to 10 to quantify their pain level where 0= no pain at all and 10= worst pain imaginable
Time frame
at 6 hours, 12 hours, 24 hours2
Patient Satisfaction
patients are asked to evaluate their satisfaction using a simple 4 point likert scale, where 4= Very Satisfied, 3= Satisfied, 2= Dissatisfied, 1= Very Dissatisfied
Time frame
Perioperative3
PACU stay
the duration of stay in PACU (postanesthetic care unit) is recorded
