Bulk Injection therapy vs AUS for Incontinence after HIFU

Seeking:
Recommendations for doctors who have performed bulking agent injection therapy on males to treat urinary incontinence.
Feedback from male diabetic patients who have undergone, penal implant with AUS operation.

You don’t have to read the following, it’s just provided for (long form) context!

My current urologist (surgeon) believes my ESD is caused by nerve damage and refuses to even consider performing bulk injections to fix my incontinence. He is all hot to install a AUS=Artificial Urinary Sphincter which I am hesitant to do . My symptoms don’t appear to be nerve related*; no tests were ordered to access the underlying cause of the ESD (I understand these tests are routinely skipped today) and the published studies on AUS show far less trouble free success in patient with diabetes. A point my doctor failed to mention!
*Nearly all the studies of bulk injections therapy on men were conducted on men with nerve damage from radial-prostetectomies, (prosthetic urethra removed). My urethra has never been cut and appeared healthy on photos after my HIFU procedure. I was not incontinent after the Hifu but because incontinent after repeated catheterizations, multiple antibiotic resistant UTIs and having large chunks of prostate being jammed deep into my bladder neck by a full bladder pressing down on it, stopping the flow of urine.
Even today my sphincter goes through the motions of working properly at low levels of urine and bladder pressure. I can step up to a urinal and release urine on command. This does not appear to be nerve damage. I believe my incontinence is more like that seen in women caused by crushing, distortion or stretching of the bladder neck during child birth. For this reason I feel my chances would be better than the published studies of men going through bulk injection therapy.
Besides, a non-invasive, nearly risk free and repeatable procedure should always be tried first even if the chances of success were approaching zero. I believe my chances are vastly better than zero and certainly better than the long term risks associated with a risky invasive, costly, surgery that will leave me with a ticking time boom (foreign device) in my body.
This is not to say I will not hesitate to take the AUS option if that was all that is left to me, but what’s the rush?

thank you PeterDisAbelard for your reply. I realize im looking for needles in a big hay stack. judging from my own doctors guidence . having had hifu rather than the usual treament means ive always been in uncharted waters. by the way, what is your opinion of the artificial urinary sphincter from a non-diabetic perspective. while my doctor raves about it I see preious few positive patient reviews but this may be the nature of the condiction and not a certique of the outcome.
thanks again, windboater.

Windboater,

In general the AUS seems to be a good option for guys who need it. If you add together the percent of guys who consider their problem fixed, and those who find their incontinence significantly improved but still an issue, you come up with impressive percentages of success. Those of us who fall in improved-but-not-perfect category will sometimes grumble that we had hoped to wind up in the other category, but if we are honest most of us find the operation worth doing.

It's not a particularly arduous surgery and one gets used to the feel and the operation of the pump fairly quickly.
