I read that the clips can only be seen on certain types of CT machines at a specific setting, if they have been in there for long enough they may get coated and the coating may show up. My first clip was found just floating in the bladder the second one was sticking the urethra and needed a bit of persuasion to come out. Mine were found with the camera while investigating the very slow flow, at times down to 0.5/sec.
It was Bri who turned it down on the slab. I was 99 percent dry soon after the RARP and I did regain my continence after each of earlier dilatations. The combination of RT and further problems means I always wear a pad and do suffer with urge inconvenience, but the bladder situation means a leak is quite small.
Bri's flow was around 5MLS/sec. Subject to advice from your team you could monitor the flow and get intervention if it gets worse. My flow declined quite rapidly, so had no choice but to have intervention. I did intermittent self dilatation after my dilations, I sometimes wonder if all the prodding into the bladder and the additional effects of the RT made the damage worse.
If the dilations are not successful there is the option of urethral reconstruction or Urethroplasty. Not a simple op.
Best wishes with you treatment. Have a look at the member "Flexi" I think he has also had stricture issues.
