Welcome to HW.
Sorry to hear of all the complications you have had following
Prostate Surgery.
It is my understanding that an AUS (Artificial Urethral Sphincter) is quite effective in correcting severe incontinence.
I'm sure others will chime in.
I developed ED Post Prostatectomy in February 2004 and underwent the Coloplast Titan Penile Implant Procedure in December 2007.
Thankfully, this completely corrected my ED and restored both my sex life and the emotional intimacy with my wife of 45 years.
The Implant is for men like myself who were not satisfied with the other ED Treatment Modalities.
Best of luck.
Bob
