What dose of gentamicin is used prophylactic urinary catheter insertion?

For prophylactic use during urinary catheter insertion, a single dose of gentamicin is typically recommended at 1 to 3 mg/kg, administered intravenously 30 to 60 minutes before the procedure. This dosage aims to reduce the risk of urinary tract infections associated with catheterization. However, specific dosing may vary based on institutional protocols and patient factors, so it is essential to consult local guidelines.
