Eligibility

All

Inclusion criteria

Inclusion criteria: Patients with a solitary upper urinary tract stone (upper ureter or renal) =2 cm in maximal diameter, who were pre-stented, candidates for RIRS using FURS and laser lithotripsy.

Exclusion criteria

Exclusion criteria: (a) multiple stones or bilateral ureteric stones; (b) persistent urinary tract infection; (c) congenital urinary tract malformations (horseshoe kidney, mal position of kidneys); (d) children less than 15 years old; (e) patients without stent prior to the procedure; and (f) pregnancy.

Design outcomes

Primary

Measure	Time frame
stone-free rate (SFR), assessed by non-contrast CTU one month after RIRS. Clinically insignificant residual fragments were defined as stone =2 mm, the widely accepted threshold on CT imaging	—

Secondary

Measure	Time frame
1- operative time, measured from the start of visualizing cystoscopy to urethral catheter insertion. 2- complications occurring intraoperatively or within 30 days, classified according to the modified Clavien system. 3- Surgeon satisfaction was evaluated according to a 5-point Likert scale (5: excellent, 4: Good, 3: Satisfactory, 2: Poor, 1: Very poor). 4- Pain was evaluated on the first postoperative day using the visual analog scale (VAS). 5- Hospital stay in days. 6- If reintervention was scheduled within 30 days, a non contrast CT scan was performed 1–2 days prior to the procedure to reassess the residual fragment status, and the modality was also documented.	—
