Suprapubic male indwelling catheters. what determines if it is a 14fr or a 16fr? i was given a curlytail cos the doc asked for a 14fr. now we know regular catheters are also available in 24fr?

There are a lot of factors that go into what size catheter is best. For example, a bigger tube is better if the urine has a lot of sediment in it or if it tends to be bloody. Smaller tubes tend to clog more if there is an infection. So, a urologist takes all these types of factors into consideration to determine what size tube is best so the tube will remain patent and free of infection.
