Final answer:
Catheter sizes for adult males typically range from 14Fr to 16Fr. The specific size chosen depends on individual patient needs, comfort and purpose of catheterization.
Step-by-step explanation:
In medicine, the size of a catheter is expressed in French units (Fr). For adult males, catheter sizes typically range from 14Fr to 16Fr. However, the selection of a specific size depends on the patient's individual needs and comfort, as well as the purpose of catheterization. For example, a larger catheter diameter (higher Fr) may be needed for patients who require rapid urine drainage or have blood in their urine, while a smaller size (lower Fr) might be more comfortable and sufficient for routine urine drainage.
