OBJECTIVE: To investigate the incidence of infectious complications after routine office nephrostomy tube replacement (NTR) in patients that did not receive antimicrobial prophylaxis (AMP).METHODS: We prospectively enrolled all patients undergoing routine office NTR between July 2018 and September 2019. Each procedure was considered an independent event. Clinical, microbiological, demographic data were collected. AMP was exclusion criterion. All patients received a questionnaire via phone call within 3 weeks after NTR investigating fever, antibiotics use, hospital admissions. Infectious complications risk was assessed with univariate and multivariate binomial logistic regression analysis.RESULTS: One hundred forty-five routine NTRs were performed. Nineteen patients receiving AMP were excluded. Median age was 78 years (interquartile range 71-81). Charlson Comorbidity Index (CCI) score was ≥5 in 53.2% of patients, 34 had positive urine culture, none received AMP. Seventeen (13.49%) patients reported fever after procedure, 9 received antibiotic therapy while fever resolved spontaneously in 8. Three patients needed hospitalization, 2 for nephrostomy malfunction, 1 for infectious complications. At multivariate analysis only CCI score ≥3 was associated (P < .001) with increased infectious complications risk.CONCLUSION: In this study fever occurs after the 13.5% of the routine NTRs, in almost half cases resolves spontaneously rather than with oral antimicrobial therapy. Avoiding AMP before routine NTR does not expose patients to life-threatening infections.

Abstract

OBJECTIVE: To investigate the incidence of infectious complications after routine office nephrostomy tube replacement (NTR) in patients that did not receive antimicrobial prophylaxis (AMP).METHODS: We prospectively enrolled all patients undergoing routine office NTR between July 2018 and September 2019. Each procedure was considered an independent event. Clinical, microbiological, demographic data were collected. AMP was exclusion criterion. All patients received a questionnaire via phone call within 3 weeks after NTR investigating fever, antibiotics use, hospital admissions. Infectious complications risk was assessed with univariate and multivariate binomial logistic regression analysis.RESULTS: One hundred forty-five routine NTRs were performed. Nineteen patients receiving AMP were excluded. Median age was 78 years (interquartile range 71-81). Charlson Comorbidity Index (CCI) score was ≥5 in 53.2% of patients, 34 had positive urine culture, none received AMP. Seventeen (13.49%) patients reported fever after procedure, 9 received antibiotic therapy while fever resolved spontaneously in 8. Three patients needed hospitalization, 2 for nephrostomy malfunction, 1 for infectious complications. At multivariate analysis only CCI score ≥3 was associated (P < .001) with increased infectious complications risk.CONCLUSION: In this study fever occurs after the 13.5% of the routine NTRs, in almost half cases resolves spontaneously rather than with oral antimicrobial therapy. Avoiding AMP before routine NTR does not expose patients to life-threatening infections.
