Passing blood through the catheter

Have you been doing any activity that might have upset it or been to the loo and strained.  I used to find sitting on the loo tugged the pipe and could give a bit of blood.  I had occasional blood almost up to the day they removed the pipe.  When they removed the catheter I didn't have blood again as far as I could tell.

I was told if the urine looks like Rosé wine it "should" be okay, if it is like red wine get it checked out. Blood in urine often looks worse than it is. Two weeks post RARP I still was getting blood in my bag. I now have a permanent Suprapubic catheter and some times get blood even though my last minor surgery was months ago. 

Do you have an out of hours urology contact number or you could possibly ring the ward you were discharged from or even your district nurse. I was given strict instructions not to let anyone change the catheter post op. If  in doubt get it checked by your medical team.

Thanks Chris

Thanks everyone for your rapid respons, I had been neither straining or doing an activity, it also looks more like a browny red ( which makes me think it might be a scab in the bladder dissolving). Tried for over an hour to get in touch with the ward no answer, so I am going to phone a specialist nurse with prostate cancer uk and see what they say.
