Introduction
Subclinical bacteriuria (SBU) may be increased in patients with comorbidities, impaired mobility, and urinary retention. Information on the association of SBU with surgical site infection (SSI) is scarce in veterinary medicine. This retrospective study aimed to determine the prevalence, risk factors, and types of bacterial isolates associated with SBU in dogs with reduced mobility and sought to explore its influence on SSI in patients treated surgically for their condition.
Materials and Methods
Medical records of dogs with orthopaedic or neurological conditions that underwent urinalysis by cystocentesis, from 3 academic referral hospitals, between 2015 and 2021 were reviewed. Dogs receiving antimicrobials or showing lower urinary tract signs (hematuria, pollakiuria, stranguria) were excluded. Demographics, duration of clinical signs, physical examination findings, results of complete blood work, urinalysis and urine culture, diagnostics, information on general anesthesia and surgery, and long-term postoperative follow-up (> 1 year) were recorded and evaluated as possible risk factors for SBU and SSI using generalized linear models.
Results
One hundred and forty dogs were included. The prevalence of SBU and the rate of SSI were 8.5% (12/140) and 9.4% (9/96), respectively. Significant risk factors for developing SBU or SSI were not identified. Urine culture was performed in 6 of 12 dogs with SBU, and 3 were positive (Escherichia coli in 2 dogs, and Staphylococcus species in 1 dog). Of the 9 dogs that developed SSI, 3 had received postoperative antimicrobial therapy.
Discussion/conclusions
Screening and treating dogs for SBU prior to surgery remains controversial. Larger studies are warranted.
