Do you avoid performing urine microscopy in patients with AKI who have COVID-19 given concern for potential aerosolization?

No. The risk is very low to non-existent. At the beginning of the epidemic we were doing that but the evidence now is not supporting that practice.

Sensitive RNA detection assays have identified SARS-Co-V2 (COVID-19) (Nomoto et al., PMID 32502614) intermittently in urine. However, attempts to culture viable SARS-Co-V2 from urine samples that tested positive for the SARS-CoV-2 genome have been negative, suggesting viral transmission via urine is low (Kim et al., PMID 32149036). Even though horizontal transmission of these viruses perhaps remains theoretical, best practices consider all biological fluids to contain potentially infectious mate...
