Design outcomes

Primary

Measure	Time frame
The mean radiation time and dose were reduced significantly in group B compared to group A as it was (157.9 ± 68.54 seconds and 32.35 ± 13.79 mGy) in group A compared to (29.44 ± 17.01 seconds and 6.07 ± 3.57 mGy) in group B. (p < 0.01). ;the time to puncture was 136.6 ± 50.78 (sec), but in group B, it was 52.20 ± 33.20 (sec) (p < 0.05);Mean operative time in the group A was 58.80 ± 14.19 minutes, compared to 42.60 ± 12.76 minutes in group B (p < 0.01). ;Successful access to the target calyx and collecting system was achieved in all patients in both groups.	—

Secondary

Measure	Time frame
The universal stone-free rate was 95.3%;According to modi?ed Clavien Dindo’s classi?cation, Grade I complications; Fever defined as axillary temperature more than 38° C occurred in 4 patients (16.0%) in group A versus 3 patients (12.0%) in group B. All patients were treated conservatively. No patients in both groups had Grade II, III (need for additional surgery, ESWL) nor Grade IV complications (Urosepsis) (Table 2) (MCp= 0.653).;The hospital stay was 2.84 ± 1.82 days and 2.20 ± 0.50 days in the groups A and B respectively (p = 0.155).	—
