Design outcomes

Primary

MeasureTime frame
Patient factors (demographic parameters such as age, sex, height, weight, body mass index, preoperative Hb, creatinine level, etc.);Renal stone factors (anatomical factors such as maximum size, volume, location, and intrarenal location of stones);Surgical factors (total surgery time, anesthesia time, intraoperative blood loss, blood transfusion, use of flexible endoscope, DJ catheter insertion, nephrostomy tube insertion), surgical results (existence of remnant stone before discharge, presence of remnant stone for 1, 3 months, length of hospitalization) Frequency and quantity of heavy analgesic use, start date of diet, date of drainage tube removal, length of stay, pain (visual analogue scale));Surgery-related prognostic factors (remnant stone incidence (stone removal rate), patient's Hb change before and after surgery, blood transfusion and complications, length of stay, and patient's pain level);Renal function-related factors: 99m-technetium-diethylene-triaminepentacetate (99mTc-DTPA) results (including information on relative renal function and separate GFR, excretion time, retention and obstruction)—

Secondary

MeasureTime frame
