Was your last birth natural? From what you have discribed it sounds like an in-out catheter (or intermittent catheter) was used (if it was placed in to drain then removed straight away - done a number of times etc). these are considerably shorter and firmer (often silicone or a pvc) as they are often designed for self-catherisation and it makes it easier to be used by the lay person. It is a possibility they used this type of catheter during a normal labour (no spinal/epidural for c/s) as it eliminates having a longer term catheter in place which may get in the way down there and therefore causes a problem with sterility.
