Asymptomatic bacteriuria before arthroplasty / 中国组织工程研究

ABSTRACT

BACKGROUND: Hematogenous spread of urinary tract infection is one of the causes of infection after arthroplasty. The significance of a special portion of urinary tract infection, namely asymptomatic bacteriuria in arthroplasty is little reported. OBJECTIVE: To explore the correlation of preoperative asymptomatic bacteriuria and infection after arthroplasty and evaluate the benefits of screening and treating asymptomatic bacteriuria. METHODS: The researchers searched PubMed, Embase, the Cochrane Library and CNKI databases to collect the clinical studies on asymptomatic bacteriuria before arthroplasty. Then, data extraction, quality assessment of the literature, and result analysis were conducted. RESULTS AND CONCLUSION: Finally, seven eligible articles were included. (1) Preoperative asymptomatic bacteriuria is significantly associated with the occurrence of postoperative prosthetic infection, but it is not a causal relationship. (2) Patients with asymptomatic bacteriuria have a high rate of superficial wound infection but no evidence shows that urinary infection is the direct source of contamination. (3) Asymptomatic bacteriuria is an indicator of increased susceptibility to infection after arthroplasty. (4) Treating asymptomatic bacteriuria before arthroplasty cannot decrease the incidence of various postoperative infectious complications. (5) Current clinical evidence does not support the routine screening and treatment of asymptomatic bacteriuria before arthroplasty.
