I have had numerous dilatations to solve my stricture, it is not uncommon for it to take 3 attempts. My flow rate would start to slow after the procedure and get critical after a couple of months. I carried out self dilatation twice a day in an effort to keep the stricture open. Although my flow was sometimes as little as 0.5 ml/sec I only went into full retention on a couple of occasions following a dilatation when I was not fitted with a catheter. My problems have been quite unusual and in no way normal.
When doing the self catheterization remember so stay calm and do not panic. Forcing a catheter in can cause trauma to the urethra and make things worse.
If he does go into retention and cannot get relief with the catheter get help with out delay.
As Sandra has already said try to control the anxiety.
Thanks Chris
