In this study inflammatory responses and infectious complications after utilizing antibiotic-loaded irrigation compared with intravenous (IV) prophylactic antibiotics. Eighty-eight participants with ureteral stones enrolled in this prospective randomized controlled trial. Participants were allocated into two groups, namely \"standard\" with 45 participants, and \"antibiotic-loaded\" with 43 participants. The \"standard\" group received standard normal saline irrigation with 1 gram of IV ceftriaxone 30 minutes before in transurethral ureterolithotripsy (TUL), while the \"antibiotic-loaded\" group received ceftriaxone-added irrigation fluid and did not receive any IV antibiotics. The laboratory tests, including Complete Blood Count (CBC), Erythrocyte Sedimentation Rate (ESR), C-reactive protein (CRP), venous blood gas (VBG), IL-6, creatinine, sodium, potassium, SIRS score, and urine culture were recorded. The continuous variables are described using either mean (standard deviation (SD)) or median (interquartile range (IQR)) and the t-test and Mann-Whitney test are used to infer them. The discrete variables are reported as numbers (percentages) and the Chi-squared test is applied to them. Statistical analyses were performed by the SPSS software (V.26, IBM) with a considering significance criterion of 0.05.
