The European Association of Urology strongly recommends taking a stone culture or urine culture directly from the renal pelvis at time of PCNL, if possible. Recent studies have cited incongruencies between negative pre-operative midstream urine cultures and intra-operative renal pelvis urine and stone culture results, ultimately correlating with post-operative infectious complications. As such, growing research has focused on determining novel biomarkers that may predict post-procedural infectious complications in stone surgery. METHODS: This is a prospective observational study. We had a total of 96 patients aged 18-60 with a pre-operative non-contrast CT scan and a complete blood count who underwent mPCNL . The Renal pelvis urine gram stain (RPUGS), Systemic Inflammation Index (SII), White blood cell ratios (NLR, PLR, and LMR) and Guy Stone Score (GSS) was determined and were interpreted if these factors could predict post-operative fever. RESULTS: RPUGS, SII, and GSS was used to predict post-operative fever and showed an overall accuracy of 71.9%, 75% and 58.3% respectively. Among the white blood cell indices, NLR and PLR had an overall accuracy of 66.7% and 62.5% respectively. All factors show significant discriminatory ability between patients with and without post-operative fever. CONCLUSIONS: RPUGS, SII, NLR, PLR and GSS are early, useful, independent, and cost-effective predictors of intraoperative bacterial status, systemic inflammation and post operative fever, which can enable the surgeon to avoid more serious adverse infectious complications of mPCNL thru early aggressive empiric anti-biotherapy.
