I'm a teacher. I never had urinary incontinence post-op. Urgency, yes. I hope things improve over time for you and am confident they will.
I had to have salvage radiotherapy and since then have experienced bowel incontinence. I saw a specialist pelvic radiation disease consultant who has brought that under control.
That said, there have been many occasions when I've literally sprinted from the classroom to go to a toilet. Thankfully, in my place, the kids will generally behave. Last week was a very bad week.....I soiled myself twice. Most weeks I'm fine but I stay close to a toilet at all times.
My colleagues know my predicament so will help out if they see me on a sprint to the toilet by sitting with my class.
I think your situation will improve.
In the meantime, talk to one of the nurses on here about it. They're great.
