For all index patients Standard; Bacteriuria should be treated. (IV) Blind basket catheter should not be performed. (IV)
For ureteral stones <10mm Option; Observation with periodic evaluation. (1A) Standard; Should be counseled on the risks of MET. (IV)
For ureteral stones >10mm Standard; Must be informed about active treatment modality. (IV) Recommendation; SWL and URS first-line treatment (1A-IV) Routine stenting is not recommended (III) Option; Stenting following uncomplicated URS is optional (1A) Percutaneous antegrade ureteroscopy is first-line treatment in selected patients (III) ; impact large stoen in upper ureter, combination with renal stone removal, ureteral stone after urinary diversion, failure of retrograde ureteral access.

UTI and urinary stone are closely related.
Urinary stone induces UTI.
UTI causes urinary stone.

Stone diseases are infectious diseases?
1. Urea splitting enzyme producing-microorganism; Struvite stone
2. Nanobacteria; Apatite stone
3. Oxalobacter formigenes; Prevent stone formation due to diminish the absorption and excretion of oxalate
