I tried both the Collagen and Teflex bulking with two different urologist. My primary, who did the RP, tried it 2 different times, both times with collagen were unsuccesful.
The secondary urologist, unfortunately the primary had health problems and had to retire, used Teflex which is the teflon coated carbon particles. This also was not successful.
All three of the above could have been due to scar tissue problems and rotorrooter work done to clear the strictures.
The 3rd Urologist - original partner of the other two ( I go through them like crazy but the 2nd guy went to a larger practice so he had time off)had tried bulking in 1999 to 2004 and did not have results which procedure warranted.
With the last stricture removal (I had 4 in 10 years), Dr Stanley and I discussed:
Bulking - which he did not have good empirical results when he used the procedure 1999-2004
Sling - I was too far gone - leaking too much and wouldn't be satisfied with results
AMS 800 - which he had good success but referred me to Cleveland Clinic.
He could implant but felt Cleveland did more and were the best choice in the area.
I had Dr Montague, Director of Urological Surgery, great guy and great place. - don't look back great
I did lots of reading and my case may have been difficult due to scar tissue. Both Urologist who did the procedure thought it would work and had some success.
Personnally, I would get a second opinion and have some flow studies done.
Bio-Feedback( anal stimulator - hurts like hell but works Microgyn Plus) and Kegel Training really helped me until I had the strictures
Good Luck with your decision.
