Delay in detection of urethral catheter misplacement in the vagina of an older adult patient due to urinary outflow during catheterization: a case report.

Background: To our knowledge, no previous case report explicitly shows that urethral catheter misplacement in the vagina cannot be ruled out even if urinary outflow is observed during catheterization.

Case Presentation: A 70-year-old female underwent urethral catheterization during induction of general anesthesia for hemiarthroplasty using a bipolar hip prosthesis. Although the urethral meatus could not be visualized, urinary outflow was observed.
