Hi @RealLifeClanger I'm so sorry for the delay in answering. I wonder if it could be related to that, though I had vaginal births so I don't have any experience with c-sections.
How did you get on with the GP?
One thing, when you mention catheters, as far as I'm aware you don't need to have a catheter when it's an outpatient cystoscopy as it will probably be a flexible one. It's meant to take about 10 minutes and then you go home. It's only the "rigid" 🙀one where they might use a catheter, I think. So while I understand fully your concern about infection, I think this is less likely with no catheter required. The thought of IV antibiotics scares me too as I had a horrible infection once from antibiotics so try to avoid them at all costs.
Interesting what you say about the lab results. Having scrutinised a bunch of these late last year, I suspect what it means is that they didn't find white cells in the sample (sometimes called pyuria) and so there was no need to culture it. Don't worry about that, the lab would have done so if there was any sign of infection.
My first lab report showed a high level of pyuria (possibly contamination when I did the sample, can be caused by vaginal discharge etc) but the only bacteria they managed to culture was a weird one that rarely causes infection, and was resistant to almost every antibiotic, I was given cipro but it didn't agree with me so I stopped it after two doses. The following two or three samples showed no white cells so I think it was contamination.
The only reason I've been referred for cystoscopy is that they still showed red cells, ie non-visible blood, so that has to be investigated but I'm hoping it's caused by low estrogen making everything sore down there. I'm in late perimenopause so that's a factor.
I really hope you get some answers soon. I will be thinking of you. I've been referred on the two-week pathway as I'm over 45, though I think the GP got muddled up as the NICE guidelines say that's for visible haematuria. So I'm accidentally jumping the queue 😇 but it's still a bit scary.
