Risk factors for postoperative infectious complications after RIRS treatment of kidney and ureteral stones

Abstract
 Introduction and aim of the study: Urolithiasis is a disease involving formation deposits in lumen urinary tract. The continued development minimally invasive treatment methods allows for more effective with greater operator comfort less risk to patient. It has been concluded that retrograde intrarenal surgery (RIRS) superior other therapeutic many respects. this study review available studies publications identify potential complications following kidney ureteral stones by RIRS, particular focus on infectious their factors.
 
 Method materials: We reviewed literature PubMed Google Scholar, using words 'urolithiasis'; 'urolithiasis treatment'; 'retrograde surgery'; 'infectious surgery'.
 Results: Among factors associated after long duration surgery, recent positive urine culture, tract infections or antibiotic use, purulent urine, nitrites, obstructed access through ureter, struvite stones, co-morbidities play special role.
 Conclusions: surgical nephrolithiasis are concern. In view knowledge factors, preventive measures should include limiting possible therapy considering use larger diameter UAS. This especially true patients abnormal results, history infection predisposing comorbidities.
