Evening Nick-
I too had sudden blood in urine, noticeable when initiating and ending urination and accompanied by a stinging sensation, at 4 weeks post op when previously the urine had gradually normalised. I think the bleeding was due to straining on the loo- on one occasion - which provoked shaky legs and an anal spasm ( I suspect this was what gave rise to the bleeding). At about the same time though, some might accuse me of overdoing things - as an example, rapidly ascending a steep sided mountain, using big 'step up' strides.
This bleeding was also accompanied by a deterioration in my continence which has partly persisted to this day ( but on Level 1 pads now). It took me three weeks of relative rest, stool softeners and scrupulous avoidance of straining on the loo before the blood cleared completely.
So in my case it was 4-7 weeks post op. Internal suturing will normally take 2-3 months to mature as long as it's not mechanically overstressed. I expect that it should have stopped bleeding by now, but maybe you had incomplete healing if you gave it a hard time. It is possible for there to be blood in the urine without it being visible to the naked eye. If you're then overdoing things it just may bleed to the point of becoming visible
I think all you can do is speak to your specialist nurse. In the meantime, if you are unable ( as opposed to noticing it's a bit of a weaker flow) to void urine- retaining the urine possibly because of clotting blood,-then you should attend A&E asap.
I have heard that clip migration can cause bleeding late post op but you're not to know that so all you can do (i Think) is to respond as I did and see how it goes. Give it a few weeks and then you won't have to repeat this when you seek specialist advice. All else being equal, they're likely to tell you to rest , avoid straining - giving the anastomosis time to heal. The longer you avoid taking this approach, the longer you're giving any of the other ( unspecified causes) things to develop into a chronic/ worsening problem.
Do what you can, as above, seek reassurance through the consultant or nurse, and monitor for changes.
Just added this edit to say that scabbing -when it matures and falls off -can lead to small brown wormy bits being urinated out and there can be fresh bleeding afterwards.
