What should be evaluated after catheter removal in cases of UTI?

Presence of renal calculi
Patient's dietary habits
Obstruction
Liver function tests

The correct answer is: Obstruction

After catheter removal in cases of a urinary tract infection (UTI), evaluating for obstruction is essential because urinary catheters can alter the normal dynamics of urine flow. Following removal, it is important to assess whether there are any blockages that could impede the passage of urine, potentially leading to retention or recurrent infections. This evaluation is particularly relevant as obstructions can exacerbate the conditions that contribute to UTIs. While evaluating for renal calculi, dietary habits, and liver function tests can be important in the broader context of a patient's health, they do not directly relate to the immediate post-catheter removal assessment necessary to ensure proper urinary function and to prevent complications. Focusing specifically on obstruction provides a targeted approach to managing the patient’s urinary health following the resolution of the UTI.
