For the treatment of a complicated UTI, in cases of delayed response, the treatment duration is:

  1. 5 days

  2. 7 days

  3. 10 to 14 days

  4. 20 days

The correct answer is: 10 to 14 days

For the treatment of a complicated UTI, a longer duration of antibiotic therapy is typically required compared to uncomplicated UTIs. Complicated UTIs involve factors such as structural or functional abnormalities in the urinary tract or the presence of underlying medical conditions that increase the risk of treatment failure or recurrence. Due to the complexity of these infections, a treatment duration of 10 to 14 days is commonly recommended to ensure complete eradication of the infection and reduce the risk of complications. Shorter durations such as 5 or 7 days may not be sufficient to fully eliminate the infection, while a longer duration of 20 days may not be necessary for uncomplicated cases.
