Fred, I don't post here often. I have posted to David in the past. Approximately 6 weeks afte my robotic surgery I developed a stricture/blockage in the bladder neck area. Had surgery after not peeing for 12 hours to open up. After cath was removed went 2 weeks happened again. This time had hard dilation in the ER (Dave know how horrible) will never allow this again. Had 4 more times that blockage from scarring ocurred with follow up surgeries along with 2 different times suprapubic caths. David they tried to change the first one out and it closed off so fast they couldn't get the other one in. The second SP was right before I was operated on by a Urology Specialist who has written books on this and is using me in one of his studies. I digress, after a year and 5 surgeries for blockages from scarring I am now 15 months status post all that mess. Like David has said in earlier posts it was nothing my origina surgeon did. The Uro Specialist who finally fixed me said around 5% can have this complication post surgery. Why was it me, only God knows. On top of all this I was born without legs and dealing with the caths was a royal pain in the a**. Life is back to normal except for the ED, my next visit with the Uro Specialist is in March and I will be talking to him about the injections. Kelly
